Concurrent with the consummation of the agreement, which is presently scheduled for November 15, 1996, Rockwell will surrender its blanket mobile terminal license, FCC File No. 1051—DSE—MP/L—95. See attached letter from Rockwell. The Rockwell authorization permits Rockwell to offer service in the lower L—band to up to 18,000 mobile terminals. AMSC respectfully requests that the Commission modify the above—referenced authorization to permit AMSC to operate up to 18,000 additional mobile terminals in the lower L—band, essentially in place of Rockwell. With AMSC‘s present authorization for 15,100 mobile terminals in the lower L—band, this will permit AMSC to operate as many as 33,100 of the specified terminals. The technical and operational characteristics of the Rockwell—manufactured equipment complies with the requirements in the above—referenced authorization. The modification would be conditioned on Rockwell‘s surrender of its own authorization. Any challenges to Rockwell‘s authorization would become moot upon the surrender of its license. AMSC has consulted with the U.S. Coast Guard with respect to this modification application and it does not object. Attached hereto is a check made payable to the Federal Communications Commission for the sum of One Hundred Thirty Dollars ($130.00) to cover the fee associated with this filing. AMSC hereby certifies that no party to this application is subject to a denial of Federal benefits pursuant to Section 5301 of the Anti—Drug Abuse Act of 1988, 21 U.S.C. §853(a).

P;}f{:}au Re: MSS Dear Mr. Caton: On September 6, 1995, the Federal Communications Commission ("the Commission") issued an Order and Authorization (FCC File No 1051 DSE—MP/L—95, DA 95—1919) granting Rockwell International Corporation ("Rockwell") authority to construct and operate, subject to certain conditions, up to 30,000 Mobile Earth Terminals ("METs") (including those authorized in the lower L—band) throughout the United States using AMSC—1 space segment capacity in the upper L—band and to operate up to 18,000 MET‘s in the lower L—band in accordance with the operational and response parameters specified by Rockwell in its application. AMSC Subsidiary Corporation ("AMSC) was similarly authorized to operate 30,000 MET‘s in the upper L—band and up to 12,100 MET‘s in the lower L—band (FCC File No. 681— DSE—MP/L—95, DA 95—1701). Rockwell currently has approximately 9000 METs deployed and operating in the lower L—band in accordance with the above Order and Authorization. Rockwell and AMSC have entered into a Letter of Intent wherein AMSC has agreed to provide service to Rockwell‘s existing Mobile Satellite Service ("MSS") customers using the installed Rockwell— manufactured mobile terminals which Rockwell is currently authorized to provide under the above Order and Authorization. Upon the execution of a formal agreement, Rockwell will discontinue its MSS business activities. Accordingly, concurrent with the consummation of the Agreement between Rockwell and AMSC,, Rockwell will surrender to the Commission its Authorization for providing MSS services. Rockwell will formally notify the Commission upon closing and the cessation of its MSS business activities. Rockwell also asks that the Commission look favorably upon any request by AMSC to increase its authorization to include the Rockwell authorization; i.e., up to a total of 33,100 MET‘s in the lower—L—band Please direct any questions to the undersigned at 703—412—6696.

INTRODUCTION 1. Rockwel!] International Corporation seeks to serve its customers using capacity on AMSC Subsidiary Corporation‘s recently launched satellite, replacing the satellite capacity it is currently leasing from Inmarsat. Toward that end, Rockwell has filed an application to modify its current interim authorization, which permaits it to operate up to 15,000 data mobile earth terminals (METs) to provide land mobile—satellite service (LMSS).‘ Its interim authorization permits the use of facilities leased from Comsat and Inmarsat in the lower L—band (1530—1544/1626.5—1645.5 MHz)* This modification application requests authorization to shift the LMSS service to AMSC‘s satellite, AMSC—1, and to increase the number of METs to 30,000. 2. We grant Rockwell‘s application in part, subject to certain technical and operational conditions in keeping with prior Commission decisions. This authorization permits Rockwell to expand its range of services using AMSC—1 space segment, and completes a major step in the creation of competition in the provision of messaging service on a worldwide basis. ‘ See In the Matter of the Application of Rockwell International Corporation for Blanket License for 15,000 Mobile Earth Stations, 7 F.C.C. Red. 942 (1992) (Blanket Aurhorization). 1 Comsat has been authorized to lease Inmarsat space segment capacity on the Marisat F—1 AOR (Atlantic Ocean Region) satellite located at 106"° W.L. and to lease an earth station at Southbury, Connecticut to AMSC for this service. Sge Blanket Authorization, supra, at para. 3. ‘ Public Notice of the application sppeared on June 7, 1995 (Report No. DS—1539). No petitions or comments were filed. On July 21, 1995, Rockwell filed a request for Special Temporary Authority (STA) to commence using the AMSC—1 space segment for its METs. That STA request is now moot. 2028876125 PAGE .GC:! DJ Un U = td (n ~ & (.)

IL BACKGROUND 3. In the Authorization, Rockwell was authorized to operate 15,000 low data rate METs anywhere in the United States for domestic LMSS coramunications using the Marisat F—] AOR satellite (through Comsat and Inmarsat) pending dedication of AMSC‘s satellite system. This order also requires Rockwel] and other domestic LMSS providers* to file a transition plan with the Cormmission within 90 days after launch of AMSC‘s satellite to assure a smooth and expeditious migration of domestic LMSS traffic to the upper L—band (1545—1559/1646.5—1660.5 MHz)! The Commission imposed no other technical requirements on LMSS terminals.‘ 4. Rockwell now seeks authority to operate a total of 30,000 METs on a permanent basis through the AMSC—1 space scgment It currently operates some 6000 METs in the lower L—band using leased Inmarsat facilities.‘ All of Rockwell‘s METs are capable of operating in both the upper L—band and the lower L—band.! Rockwell also states that it will continue to provide service to its existing customers, and its says it will use the remainder of its requested 30,000 METs in the upper L— band for future growth 5. Rockwell states that the technical specifications for its data MET‘s, which are essentially Inmarsat "Standard—C" units, are the same as those discussed in the Authorization. AMSC says the change is only that the terminals will use the AMSC—1 space segment (instead of Inmarsat) and operate over a different range of frequencies. The 30,000 MET‘s for which Rockwel! seeks permanent authority will be capable of operating in both the lower L—band and in the upper L— band, where AMSC is now authorized to operate its satellite" * AMSC was similarly authorized to operate 30,000 METs. BlanketAuthorization, supra. Other interim LMSS providers were also authorized, subject to obtaining a lease from Comsat to access Inmarsat space station capacity. Id. + This application is filed pursuant to this requirement. 86 See Authorization, supra. See also In the Matter of the Application of American Mobile Satellite Corporation for Blanket License for 30,000 Mobile Earth Stations, 8 F.C.C. Red. 6310 (1993) (30.000 Reconsideration). ?

Application of AMSC in File No. 681—DSE—MP/L—95, DA 95—1701 (August 1, 1995) (authorization of AMSC to provide 30,000 METs in the upper L—band using fufl-duple( equipment, and under Special Temporary Authority and wa.rvcr ofUS315 to use METs cum:ntlyin use in the lower L—band for two years) ; see also sua sponte Recon. in File No. 68 1—DSE—MP/L—95, DA 95-1723 (August 4, 1995) (expanded waiver to include 12,000 additional existing METs). ° See Licensing 4 F.C.C.

We stated, at para. 13 of the MEIs that "This MET operating authorization . . . encompasses operation only in the frequencies 1545—1559/1646.5—1660.5 Mli4z [the upper L—band]." The issue ofAMSC‘s 2 2228875125 PAGE .CRZ

6. In both the upper L—band and the lower L—band, Mobile Satellite Service (MSS) operators such as Rockwell must be able to provide "real—time preemptive capability" for certain safety and distress services." In the upper L—band, the relevant safety—related service is the Aeronautical Mobile Satellite (Route) Service (AMS(R)S), while in the lower L—band the relevant safety—related service is the Global Maritime Distress and Safety System (GMDSS). Rockwell‘s proposal to transition its MEIs from the lower L—band to the upper L—band thus requires us to determinz whether Rockwell‘s new METs are consistent with the safety requirements of a different range of frequencies, in which somewhat different safety considerations may apply. IIIL DISCUSSION 7. We will modify Rockwell‘s authorization to permit operation of up to 30,000 METs in the upper L—band, on the condition that those MET‘s provide real—time preemptive capability as described in this Order. However, as we discuss below, we will not authorize Rockwel!‘s operation of its existing 6000 METs"‘ in the upper L—band because of concerns expressed by the Federal Aviation Administration (FAA) and the National Telecommunications and Information Administration (NTIA) over the real—time preemptive capabilities of these terminals. Instead, we will allow Rockwell to continue operating its existing MET‘s in the lower L—band temporanily, until it can introduce METs that permanent use of the lower L—band for its services, as well Rockwell‘s use of the lower L—band, is pending in File No. 59—DSS—MP—MP/ML—93. Rockwel! states that it is willing and capable of operating in the lower L—band over AMSC—1. In and the Chief, International Bureau stated that, in view of the complex policy and legal issues associated with File No. 59—DSS—MP—MP/ML—93, he would deny AMSC‘s request for Special Temporary Authority to operate its 30,000 METs in the lower L—band. Rockwell has not sought such authority in its subject application. Nevertheless, we find that the public interest will be served by granting Rockwel] authority to operate 6,000 existing and 12,000 additional METs in the lower L—band using AMSC—1 space segment. See paras. 15—18, infre. In all other respects, Rockwell will be expected to comply with its commitments to transition to the upper L—band. ° Section 2.106 ofthe Commission‘s Rules contains the Table of Frequency Allocations. The Table includes footnotes which denote stipulations applicable to both U.S. Government and non—Government stations. Each such footmnote contains the "US" prefix. Other foomotes in the Table apply to international spectrum use; these do not contain a prefix. Footnote US308 states that in the 1549.5—1558.5/1651—1660 MHz bands the AMS(R)S requirements that cannot be accommodated in the 1545—1549.5 MHz, 1558.5—1559 MHz, 1646.5— 1651 MHz and 1660—1660.5 MHz bands shall have priority access with real—time preemptive capability with respect to communications in the MSS. Systems not interoperable with AMS(R)S shall operate on a secondary basis. Account shall be taken ofthe priority ofsafety—related communications in the MSS. Note 729A states generally that, notwithstanding any other provision of the Radio Regulations relating to restrictions in the use ofthe bands allocated to AMS(R)S for public correspondence, the bands 1545—1555 MHz and 1646.5—1656.5 MHz may be authorized by administrations for public correspondence with aircraft earth stations. Note 730C, which applies to United States domestic service, states that the band 1555— 1559/1656.5—1660 MHz is allocated to MSS on a primary basis subject to the conditions that AMS(R)S shall have prionity access and immediate availability over all other mobile—satellite communications within a network operating under this provision; mobile—satellite systems shall be interoperable with the AMS(R)S; and account shall be taken of the priocrity of safety—related communications in the other MSS services. !‘ Rockwell‘s original application stated that there are 4,500 extant METs, but its STA Request indicates there are 6,000. We will rely on the later figure of 6,000 in our analysis herein. 3 22z70e97581 €0 CJ () ND ) 11 n U n D

satisfy the concerns of the acronautical community. In OrderAuthorization, AMSC we granted AMSC Specxal Temporary Authority to operate AMSC—1 in the lower L—band so that the existing METs can migrate to AMSCs satellite as required by our prior orders. 8. — The upper L—band is allocated to both MSS and AMS(R)S, which governs safcry-reated communications and regularity of aircraft flight. In its AMS_QL;;_gnsmgQrd;: the Commission required AMSC to mcorporate tnto its overall system design whatever minimum requirements for aeronautical satellite communications systems are endorsed internationally through the International Civil Aviation Organization." 9. This issue was also raised in the 200,000METs proceeding, following concerns expressed by the FAA and NTIA on the matter of protection of safety—related communications and distress cornmunications in the upper L—band." In the 200,000 Order, the Chief, International Bureau conditioned AMSC‘s use of the upper L—band on several operational/technical conditions, including: (1) All METs that do not continuously monitor a separate signalling channel shall have provision for signalling within the communications channel; and (2) Fach MET shall automatically inhibit its transmissions on any or all channels receiving a channel—shut—off command on a signalling or communications channel it is receiving from its associated Land Earth Station The voice METs at issue in 200.000 complied with these conditions. Both the voice METs and AMSC‘s operating system fiunction in a "full—duplex" mode (1.e., simultaneous transmission and reception of signals) permitting preemption of MSS for AMS(R)S traffic on a virtually instantaneous basis." This comports with ITU Regulations Footnote 730C, which requires immediate availability of frequencies for AMS(R)S, and Foomote US308, which requires real—time preemprive access for AMS(R)S." We believe that these requirements are equally applicable to Rockwell‘s METs. 10. Rockwell states that its data terminals will operate in a "half—duplex" mode —— that is, they cannot receive signals while they are transmitting. The instruction to the data MET to cease transmitting comes from a land earth station on a TDM (time division multiplexed) carrier, but the MET cannot act on that instruction while it is transmitting. In a worst—case situation under normal operating conditions, a Rockwel] data MET could transmit for as long as 24 seconds, though the length of time the MET may actually transmit can be limited by the protocol used in the system and " Ses AMSC Licensing Order, supra. 2 200000Blanket supre " Id., para. 18. 5 See Supplemental Letter to Secretary, FCC from Chicf Scientist, AMSC, dated March 23, 1995, at 3.

further limited by the Rockwell mobile terminal‘s software. The typical transmission length, Rockwell states, is less than four seconds with an average length of 0.502 seconds. Rockwell further states that 99.98 percent of all transmissions during a recent test of their system were less than 4 seconds in duration and 100 percent of the transmissions were less than nine seconds in length. 11. NTLA and FAA did not file comments in this proceeding, but we incorporate their positions herein because the issues are identical. NTIA and FAA object to any MET that is half— duplex rather than full—duplex in design, fLe., cannot receive a command for real—time preemption during MET transmissions. According to the FAA, Rockwell cannot comply with Footnote US308 to the U.S. Table of Allocations, or with Footnote 730C of the TTU‘s table of frequency allocations, which require immediate preemption of non—AMS(R)S transmissions for AMS(R)S transmissions. FAA recommends that the FCC: (1) require that half—duplex METs be modified for full—duplex operation, with real—time preemptive capability, or (2) grant authonity to allow continued use of extant terminals with the AMSC—1 satellite in the lower L—band only. 12. Rockwell suggests that the vast majority of data transmissions, even on half—duplex terminals, could be preempted in seconds. More fundamentally, Rockwell argues that a number of features of its overall system, working together with AMSC‘s system, enable it to provide real—time preemption even though not every AMSC ferminal can do so. Rockwell states that AMSC‘s Network Operations Center will continuously monitor not only the data traffic, but also voice traffic and all other types of traffic on the system. As noted in the and the AMSC Network Operations Center will allocate frequencies to these various networks, taking frequencies away from lower—priority users and giving them to higher—priority users, such as AMS(R)S users. In addition, the Network Operations Center will always maintain a "reserve pool" of unoccupied frequencies, which can be allocated to AMS(R)S without preempting any other user. 13. Rockwell states that the maximum time needed to shut down the message channel associated with its METs is about 61 seconds. For 99.98 percent of the messages sent by its METs the required time to cease transmission is approximetely 41 seconds." Rockwell further states that message length and half—duplex operation add minimally to the overall preemption time, particulatly because the maximum message length can be limited to a few seconds." It clairms that conversion to full—duplex would not significantly improve preemption time." 14. The primary question before us with regard to preemption, as it was in AMSC andAuthorization, is whether Rockwell‘s statistical, systematic approach to achieving real—time preemption satisfies Footnotes US308 and 730C. For the same reasons we found that it did not in and we find that it does not here either. Notwithstanding Rockwell!‘s arguments that it has satisfied the real—time preemptive access requirement, we remain reluctant to overrule NIIA. Therefore, we conclude that Rockwell may not use its half—duplex METs in the upper L—band at this time. We now proceed to discuss whether Rockwell may continue to operate its data MEIs in the lower L—band, as suggested by FAA and NTIA by its comments in the AMSC . ?

proceeding." 15. andpremption. Just as Footnote US3O8 protects AMS(R)S in the upper L—band, US315 is intended to protect maritime mobile—satellite distress and safety communications domestically by providing priority access and real—time preemptive capability for distress and safety communications."" The language of US315 is sufficiently similar to US308 that we cannot conclude that US308 requires full—duplex METs but US315 does not. We are therefore inclined to believe that Rockwel!l ({like Inmarsat, Mexico, and others, including AMSC) currently provides mobile satellite service in the lower L—band frequencies using MET‘s that do not comply fully with the requirements of Footnote US315 to Section 2.106 of the Commission‘s Rules. The low data rate "Standard C" terminal and similar models used by Rockwell and others do not operate in a full— duplex mode and therefore are not capable of real—time termination of METs transmission (Le., they cannot interrupt a transmission once it has commenced). 16. However, as we discussed in and the maritime distress and safety services have been operational for years and are sufficiently robust and dynamic to permit us to consider less rigorous enforcement of US315 than we must require for the aeronautical services under US308. The aeronautical distress and safety—related services are untested and are potentially more time—sensitive than their maritime counterparts due to higher aeronautical vehicle velocities. We also note that the half—duplex manitime mobile satellite service (MMSS) MET‘s curtently in use have not adversely affected the effectiveness of the Global Manitime Distress and Safety System (GMDSS), although operation of the GMDSS began only three years ago and is not fully implemented. As we observed in AMSCand Authorization, however, in the next two years there may be a substantial increase in the number of MMSS METs in use worldwide. 17. Based on Rockwell‘s statistical analysis of average message length and related information, we believe that, under current conditions, existing data MET‘s in the lower L—band will provide sufficient distress and safety communication priority to comply with the intent of US315. It is also our understanding from the United States Coast Guard and NIIA that an additional 12,000 METs can be safely accommodated in the lower L—band for a two—year period. For these reasons we believe it appropriate to issue a temporary waiver of Footnote US315 to Section 2.106 of our Rules. This waiver will continue to require Rockwell to operate on a secondary basis to, and avoid harmful interference to, GMDSS. 18. Further, the waiver applies only to METs currently used by Rockwell and an additional 12,000 such METs, and only insofar as they are used to access AMSC‘s space segment. The waiver will terminate on July 31, 1997. In this way, we can be reasonably assured that when MMSS METs are more prevalent and GMDSS preemption therefore potentially more urgent, the ® See OrderAutborization at para. 17. * US315 states as follows: In the frequency bands 1530—1544 MHz and 1626.5—1645.5 MHz maritime mobile— satellite distress and safety communications, e.g., GMDSS, shall have priority access with real—time preemptive capability in the mobile—satellite service. Communications of mobile—satellite system stations not participating in the GMDSS shall operate on a secondary basis to distress and safety communications of stations operating in the GMDSS. Account shall be taken of the priority of safety—related communications in the mobile—satellite service. 6 t D U J m ~ ) D G C & t DJ D Ru D

requirements of US315 will be followed strictly."2 We have already conditioned AMSC‘s METs authorization on AMSC maintaining its continued use of its AMSC Network Operations Center management and operational standards as set forth in its application and pleadings. Such a requirement need not be imposed on Rockwell because Rockwell will subscribe to AMSC‘s space segment and will be subject to AMSC‘s Network Operations Center. However, we will require Rockwel] to maintain the current message—length statistics as indicated in its application and pleadings. 21. MLMW Section 25.202(f) of the Commission‘s Rules contains the out—of—band emissions limits that apply to the instant case. Our review of Rockwell‘s application‘" reveals no apparent out—of—band emission violation of Section 25.202(f). While the issue was not raised in this proceeding, we believe it useful to state, asmdxdmAMSQ_Q_mgx_md Authorization, supra, that any questions concerning out—of—band emissions should in the first instance be addressed by the parties themselves." Further, any perceived potential for interference with other countries‘ systems should be resolved in a cooperative way, based on technical analysis and discussion among the users of the spectrum." 22. band ion The long—term use ofthe lower L—band is currently being considered by the Commission in File No. 59—DSS—MP—MP/AML—93. We cannot and do not predict whether the Commission will ultimately assign that spectrum to AMSC or to other applicants. We have concluded, however, that the public interest will be served by granting Rockwell authority to operate its existing METs plus 12,000 additional MET‘s in the lower L—band, using AMSC—1 space segment. Doing so will permit Rockwell to compete in the provision of domestic MSS services — a policy the Commission has long pursued. Further, Inmarsat will not be prejudiced because the Cornmission‘s prior orders contemplated that Rockwell, AMSC, and others would be operating data METs via AMSC—1 by this time. Finally, we reject any suggestion that this authorization in any way predetermines the outcome of File No. 59—DSS—MP—MP/ML—93. 23. (GPS. We are concerned that Rockwell‘s METs include sufficient out—of—band emission suppression to protect the Global Positioning System (GPS) and the Russian Global Navigation Satellite System (GLONASS) which operate on frequencies near L—band. In its application, Rockwell states that it complies with the criteria for meeting the spurious emission level standards to protect GPS contained in a Memorandum of Understanding (MOU) armong the FCC, NTIA, and FAA.*" The purpose of the MOU is to assure coexistence between GPS and GLONASS receivers and MSS METs operating in bands near the frequency bands used by GPS and GLONASS receivers, including METs to be used with AMSC‘s satellites. The provisions of the MOU establish specific out—of—band emissions * At the end of the waiver, period no Rockwell data METs will be in the lower L—band, unless the Commission so authorizes them in the lower L—band proceeding. This will complete implementation of the transition plan required by our Authorization.

limitations and notification requirements in the event of detected harmful interference."" We believe that these provisions resolve any concern with regard to Rockwell‘s data METs causing harmful interference to GPS receivers from Rockwell‘s s METs operating in bands near the frequency bands used by GPS and GLONASS receivers. 24. Hazard Radiation Analysis. In a supplemental filing dated August 17, 1995, Rockwel] provides a radiation hazard analysis for its data METs. Rockwell states that its data METs will not exceed the revised maximurm permissible exposure (MPE) limits established in [EEE/ANSI C95.1—1991. Rockwell indicates that the antennas used with its METs are quadrafilar helix in design, 10.1 em tall and 3.5 em in diameter. Applying the MPE limit of 1.1 mW/em?" under ANSI C95.1— 1991, the separation distance required for Rockwell‘s MET antennas is 5.4 cm (2.1 mchcs)28 Rockwell further states that its MET antennas will be mounted within a radome enclosure having a radius of 11 cni and therefore will pose no radiation hazard to unsuspecting persons nearby. Based on this analysis, we find that Rockwell‘s METs meet the ANSI C—95—1991 MPE limit and are in compliance with Commission Rules regarding radiation hazards. We note, however, that subsequent Commission action in ET Docket No. 93—62 may affect future Rockwell METs." IV. CONCLUSION 25. Our authorization to Rockwell to operate up to 30,000 data METs using AMSC—1 space segment represents a further step in the creation of competition in the provision of messaging service on a worldwide basis. Accordingly, we find, pursuant to sections 309 and 319 of the Communications Act of 1934, that the public interest will be served by granting Rockwell authority to operate approximately 6,000 existing data METs, which are using Inmarsat facilities in the lower L— band, using AMSC—1 space segment. In addition, we find that the public interest will be served by granting Rockwel] authority to operate an additional 12,000 such MET‘s in the lower L—band, also using AMSC—1 space segment. Authority for these data MET‘s is issued pursuant to a temporary waiver of note US31S of Section 2.106 of the Rules. Rockwell may construct and operate a total o" up to 30,000 METs in the upper—L band (less the number of METs it uses at the same tume in the lower L—band), if the METs comply with the full—duplex requirement and the other, related * RTCA (formerly The Radio Technical Commission for Aeronautics) Special Cormmittes 165 (SC—165) is currently developing equipment performance standards in the L—band, as well as the standards for METs adopted in the Commission‘s proceedings. See American Mobile Satellite Corp., 7 F.C.C. Red. 942, 945—47 (1992). See also RTCA, Guidance on AMSS End—to—End System Performance (DO—215, may 13, 1993); RTCA, Minimurm Operational Standards for AMSS, Part A (DO—210 Part A, June 19, 1992), and Part B (DO—210 Part B, May 13, 1993). RTCA SC—159, WG—6, is currently addressing matters of interference to Global Navigation Satellite Systems by MSS operations. * Rockwell assumes a duty cycle of 1/30, Le., a typical maximum message transmission time from an MMS terminal of 1 minute over any 30 minute period. The maximum 1600 byte message length for its MET is 23.78 seconds (0.396 minutes). The far field of Rockwell‘s METs begins at a distance of 11.2 enfrom the antenna. The power density at the beginning of the far field is 0.10 mW/em‘. * ET Docket No. 93—62 addresses revised standards for radiofrequency radiation emissions, including exposure guidelines for people using various kinds of radio transmitting devices. The currently applicable standard for these frequency bands under Commission Rules is in ANSI C95—.1—1982, and is 5 mW/cem‘. See 47 CFR § 1.1307(). 2028875126 PAGE .BBEf

Accordingly, IT IS ORDERED that, pursuant to Section 0.261 of the Commission‘s rules on delegation of authority, 47 C.F.R. § 0.261, application File No. 1051—DSE—MP/AL—95, IS GRANTED and Rockwell IS AUTHORIZED to operate its existing data METs and an additional 12,000 data METs using AMSC—1 space segment an specified frequencies in the lower L—band (1530— 1544/1631.5—1645.5 MHz) throughout the United States, subject to the conditions set forth herein. Further, Rockwell IS AUTHORIZED to construct and operate a total of 30,000 MET‘s (including in this number those METs authorized for use in the lower L—band) throughout the United States, using AMSC—1 space segment in authorized frequencies in the upper L—band (1545—1559/1646.5—1660.5 MHz), provided such METs operate in a full—duplex mode and fully comply with the requirements of Footnotes 730C and US308 to Section 2.106 of the Rules, and as set forth herein. 27. IT IS FURTHER ORDERED that Footnote US315 to Section 2.106 of the Commission‘s Rules IS WAIVED to permit Rockwell to operate all its METs in use on the date of release of this order, and an additional 12,000 such MET‘s, in the lower L—band in accordance with the operatioral and response parameters set forth in Rockwell‘s application. Under this waiver, Rockwell shall opetate on a secondary basis to safety and distress commmumications of those stations operating in the GMDSS. Further, the waiver shall terminate on July 31, 1997.
