            COMMENTS OF STARSYS GLOBAL POSITIONING, INC. ON
              AMENDED APPLICATION OF FINAL ANALYSIS, NC.


                       STARSYS Global Positioning, Inc. ("STARSYS"), by its attorneys,

hereby comments on the May 25, 1995 amendment that Final Analysis, Inc. ("Final

Analysis") has filed in connection with its above—captioned Experimental Radio

Services applications. As shown below, Final Analysis has made adjustments in its

technical and reported operational plan that ameliorate some of the concerns identified

by STARSYS in its initial comments and on reply. However, there are other aspects

of the Final Analysis program —— matters which were addressed earlier by STARSYS

and which are not affected by the recent amendment —— that require STARSYS to

continue to object to the approval of the program proposed by Final Analysis.

                       At the outset, STARSYS wishes to reiterate that the stated desire of Final

Analysis to examine the suitability of frequency bands between 100 and 500 MHz for

prospective compatible use by systems in the Non—Voice, Non—Geostationary Mobile

Satellite Service ("NVNG MSS") is legitimate, and should be encouraged. See

STARSYS Comments, File Nos. 4682—EX—PL—95, at 2 (filed April 5, 1995). To a

                                                   —2_


greater extent now, Final Analysis‘s proposed experimental program seems to advance

this objective. For example, the proposal to test bands at 455—456 MHz and 459—460

MHz is consistent with proposals being made in advance of the 1995 World

Radiocommuication Conference. Nevertheless, the fact remains that Final Analysis‘s

experimental program goes much farther than is necessary in at least one key respect,

and it leaves unanswered the serious questions about its program that STARSYS and

others levelled during the pleading cycle on Final Analysis‘s original submission.

                       First of all, while Final Analysis has reduced its required number of

remote transmitters from 9,240 to 1,848, this number is still too high. STARSYS

questioned Final Analysis‘s original request on several counts. It observed that Final

Analysis provided no information as to how the terminals would be used, and that it

failed to state the character of the terminals‘ use —— shortcomings which were neither

addressed in Final Analysis‘s opposition pleading or in the recent amendment. See

STARSYS Comments at 7—8; STARSYS Reply and Motion to Strike at 2—3 & n.2.

Indeed, Final Analysis still has yet to state whether test messages only will be utilized,

and if not, what entity or entities will be making use of the terminals, and it has not

identified the terminals‘ manufacturer. STARSYS also observed that in order to

conduct and record frequency band characterizations in the frequency bands to be

studied, it is unnecessary for Final Analysis to have even one user terminal.

                                                   —3_


                       Although the evidence pointed (and still points) to a scenario whereby

Final Analysis has impermissible commercial objectives for its supposed

"experimental" system, STARSYS suggested that the Commission allow the applicant

to employ a maximum of 100 user terminals with its system. STARSYS Comments at

8. Because the current request, though reduced from the original, is still both

excessive and completely unexplained, STARSYS continues its objection to this aspect

of the experimental program, and urges the Commission to cap at 100 the number of

remote user terminals it may authorized Final Analysis to use. At the very least, the

Commission should require Final Analysis to come clean on its intentions and

justifications for the number of remote user terminals it proposes.

                       Next, STARSYS continues to object to Final Analysis‘s specification of

downlink channels that overlap with STARSYS‘s proposed NVNG MSS downlink

channels at 400.595—400.645 MHz, and in the 137—138 MHz band (where Final

Analysis now proposes a 30 kHz channel proximate to the most sensitive portion of

STARSYS‘s signal). The Commiussion stated last week that it intends to act on

STARSYS‘s application shortly. See Orbital Communications Corp., FCC 95—135,

slip op. at 1—2 & n.3 (released June 2, 1995). Nothing Final Analysis has filed to date

in this proceeding addresses STARSYS‘s argument that the proposal of Final Analysis

to operate directly on top of frequencies applied for by STARSYS violates the

guideline from the Commission‘s Policy Statement on Experimental Applications, 7

FCC Red 4586 (1992) ("Policy Statement"), which specifies that the grant of an


42171.1/060795/15:54


                                                  —4—


experimental application "should be consistent with [the Commission‘s] general policy

to protect against harmful interference to licensed stations." Id. As STARSYS noted,

Final Analysis has essentially admitted that the co—channel downlink at 400.62 MHz

would cause harmful interference to STARSYS. See STARSYS Reply Comments and

Motion to Strike at 4 (citing Final Analysis Opposition at 8). Final Analysis must be

precluded from using these interfering channels, or required to demonstrate that its

proposed use will not interfere with the NVNG MSS use to be effected by STARSYS.

If the Commission sees fit to authorize Final Analysis, STARSYS would be satisfied

with a condition that requires Final Analysis to cease use of the overlapping

frequencies upon the launch of the first STARSYS satellite. See, e.g., Mobile

DataComm Corporation, DA 95—664 (Int‘l. Bur., released April 3, 1995).

                       There are three additional areas where Final Analysis‘s amendment

leaves unanswered serious questions raised by STARSYS and others as to the

experimental program: Specifically, Final Analysis has not amended its application to

delay the originally—proposed August 1995 launch date. Even for a company that

professes to have the extraordinary abilities Final Analysis claims for itself (see Final

Analysis Opposition at 9—10), 60 days is too short a time to construct a satellite.

STARSYS renews its request for a Commiussion investigation into whether Final

Analysis or its NVNG MSS applicant subsidiary have unlawfully commenced

construction of the proposed experimental satellite, and if so, to determine the impact

this unlawful activity has on the companies‘ character qualifications.

                                                   —5.


                       It also appears that Final Analysis‘s proposed satellite and mobile

terminals are fully programmable, and capable of a broad range of commercial

operations. Such a program is, as STARSYS has noted before, inconsistent with the

Policy Statement. A more limited version could still accomplish the program

objectives officially stated by Final Analysis, without being perceived as an effort to

circumvent the Commission‘s rules and processes.

                       Lastly, Final Analysis has failed to respond to STARSYS‘s

demonstration that the uses Final Analysis proposes for its requested master ground

station in Logan, Utah, would violate the explicit condition that has been placed on

that authorization. See STARSYS Reply Comments and Motion to Strike at 7 (citing

Final Analysis License, Call Sign KE2XGU, at 2).

                       In sum, Final Analysis‘s amendment represents a nod in the right

direction, but still leaves unanswered many serious questions. On balance, STARSYS

believes that the gravity and number of the unanswered questions preclude the grant of

the application, as currently amended. Accordingly, STARSYS continues to urge the

Commission to deny Final Analysis‘s above—captioned experimental applications.

               Proposals for Agenda Items 2.1la)    and 3.0)

                 Mobile—Satellite Services Below 1 GHz

Introduction:

        The attached U.S.   proposals address issues related to
mobile—satellite services (MSS) operating below 1 GHz.  WARC—92
allocated 3.45 MHz of primary spectrum to this service.  Since
that time, the United States has licensed one non—geostationary
MSS system to operate in the U.S. in these new primary
frequencies and has six pending system applications.   Satellites
from the first system have already been launched.

     Experience with the use of the MSS bands below 1 GHz, as
well as recent studies of the ITU—R that are reflected in the
Report of the Conference Preparatory Meeting  (CPM), indicate
that several modifications could be made to existing MSS
frequency allocations to facilitate their use.         Proposals to
facilitate the use of existing allocations for mobile—satellite
services may be made pursuant to agenda item 2.1(a) .
Accordingly, the U.S. proposes to modify a number of footnotes to
the 148—150.05 MHz band to improve coordination efforts in this
band.     In accordance with a suggestion from the Voluntary Group
of Experts that allocations be made, where possible, to the
broadest category of service, the U.S. further proposes to change
the Land Mobile—Satellite allocation in the 149.9—150.05 MHz band
to a more general Mobile—Satellite Service.

     In addition to discussing the improvement of existing MSS
allocations, the CPM Report states that additional spectrum will
be necessary to meet the near—term requirements for MSS below 1
GHz.  Because WRC—95 is empowered to make limited allocations to
MSS pursuant to agenda item 3 (d), if such allocations are
necessary, the United States proposes to modify the international
Table of Allocations to include 6.105 MHz of spectrum to be used
by MSS, or associated feeder links.          The bands suggested for
allocation to MSS include 216—216.5 MHz (space—to—Earth) and
217.5—218 MHz (space—to—Earth), 399.9—400.05 MHz (Earth—to—
space), 401—404 MHz ((space—to—Earth with the 401.2—401.7 MHz
seqgment allocated to MSS on a secondary basis), 455—456 MHz
(Earth—to—space) and 459—460 MHz (Earth—to—space).

coordination distance threshold is a more useful approach to
facilitate coordination across national boundaries; this approach
is supported in the report of the CPM.

Reason :

       The Report of the CPM states that additional spectrum will
be necessary to meet the near—term requirements for MSS below 1
GHz.   As a consequential change of adding allocations for the
mobile—satellite service in the 401—404 MHz bands, it is
necessary to upgrade the allocations for the meteorological—
satellite and Earth exploration—satellite services to primary
(see also Resolution 710 (WARC—92)) .

                    procedures set forth in MOD Resolution 46.   Until
                    sharing criteria are developed, in the band 401—
                    404 MHz, stations in the mobile—satellite service
                    shall not cause harmful interference to the
                    meteorological aids, meteorological— satellite,
                    Earth exploration—satellite, and Space Operations

                    urgency by the ITU—R and reviewed by a future
                    competent world radiocommunication conference.    In
                    making assignments to the space stations of the
                    mobile—satellite service in the 401—404 MHz band,
                    administrations shall take all practicable steps
                    to protect the radio astronomy service in the
                    406.1—410 MHz band from harmful interference from
                    unwanted emissions.  _Unwanted emissions from
                    mobile—satellite service space stations operating
                    in the 401—404 MHz band shall not cause harmful
                    interference to the mobile—satellite service in
                    the 406—406.1 MHz band (649A (SS5.267) applies) .

Reason :


       RR 648A is necessary to ensure proper sharing criteria are
developed by the ITU—R as outlined in Resolution YYY.
