Part 25), per In the Matter of The Establishment ofPolicies and Service Rulesfor the Non—Geostationary Satellite Orbit, Fixed Satellite Service in the Ku—Band, TB Docket No. 01—96, Adopted April 18, 2002, Released April 26, 2002; ECC 02—123.

to construct and operate the Pentriad satellite system.2 The Pentriad satellite system proposed by Denali will operate in quasi—geostationary highly elliptical orbits ("HEO"), and utilize the Ku—band for space—to—Earth transmission." The Commission has proposed to amend Section 25.146 Licensing and operating authorization provisions for the non—geostationary satellite orbit fixed—satellite service (NGSO FSS) in the bands 10.7 GHz to 14.5 GHz, and has requested the applicants to this licensing proceeding to submit conforming amendments to their respective applications. Denali, as an applicant affected by the proposed rule changes, provides the following additional information to satisfy the proposed amended regulation: \ (1) A demonstration that the proposed system is capable ofprovidingfixed—satellite services on a continuous basis throughout thefifty states, Puerto Rico, and the U.S. Virgin Islands, U.S.; and (2) A demonstration that the proposed system be capable ofprovidingfixed—satellite services to all locations asfar north as 70 deg. latitude and asfar south as 55 deg. latitudefor at least 75 percent ofevery 24—hour period. In order to comply with the Commission‘s requirement to provide for global coverage of services in the Ku—band, Denali amends its current application with the addition ofthe Southern * See, In re Application ofDenali Telecom LLC, Consolidated System Proposalfor Authority to Launch and Operate Thirteen Satellites in the Pentriad System, an International Joint Venture Constellation of Thirteen Satellites Operating in Linked Molniya Highly—Elliptical Orbits in the International Fixed—Satellite Service and the Mobile Satellite Service (filed September 26, 1997), FCC File No. 160—SAT—P/LA—97(13). * Denali‘s application requests authority to construct and operate satellites in the international Pentriad system. The satellites will operate in linked Molniya highly elliptical orbits, and will provide international Fixed—Satellite services in the Ku—band (11.7—12.7 GHz) to users in the Northern and Southern Hemispheres. The Pentriad system will be the first commercial Western use oflinked Molniya highly elliptical orbits.

Operation Configuration ("SOC") —— covering the Earth‘s Southern Hemisphere. The SOC will service areas at 30 deg. west longitude (over the southern Atlantic Ocean) and 150 deg. east longitude (over Australia), and thus will be able to provide greater service capacity —— greater than what would have been available from its initial constellation design contained in the Denali application —— available to all Southern Hemisphere continents, including Antarctica. (See Exhibits 1 and 2 to the FCC Form 312 for Southern Hemisphere Service Area coverage). This Pentriad system design continues to allow for the implementation of multiple systems in other Molniya orbits by maintaining spatial diversity between the operational ares of the satellites (geosynchronous satellites at zero degrees Latitude plus or minus five degrees North and South and the Pentriad HEO satellites operating between 55 degrees South Latitude and 70 degrees North Latitude). Thus there is maintained an effective separation between GEO satellites and tie operational are ofthe Denali HEO satellites. Services will be initiated in three phases: (1) an Initial Operation Configuration ("IOC:") in the Northern Hemisphere; (2) a Full Operation Configuration ("FOC") in the Northern Hemisphere; and (3) a Southern Operation Configuration ("SOC") in the Southern Hemisphere. Denali is ready to proceed with the construction of the Pentriad system, so that the first three Pentriad spacecraft can be launched into an IOC to meet milestone dates (as to be specified by the Commission‘s authorization) to provide broadband services to North America and North Asia, and for subsequent deployment of the remainder ofthe constellation to follow for services to the Southern Hemisphere. In the Southern Hemisphere, three satellites (Flight Models 13 to 15) will be launched into three distinct Molniya orbits (63 degree inclination) with 12.0 hour orbital periods. These satellites will be used to provide service to South America, Africa and Australia. The Southern Hemisphere coverage will be deployed after the IOC ofthe Northern Hemisphere. The FOC of the Northern Hemisphere will follow the Southern Hemisphere deployment. In the FOC, all operational Pentriad satellites (Flight Models 1 through 15) will operate in six orbital planes. The three Northern and Southern orbital planes will be separated by one hundred twenty degrees (120°) around the equator ofthe Earth. The three operational satellites in each orbital plane will be spaced evenly in their respective plane. Operating together, the nine

operational satellites will provide continuous twenty—four (24) hour broadband coverage to five overlapping service areas in the Northern Hemisphere, while the three Southern Hemisphere satellites will provide services to the southern areas for at least 75 percent of every 24—hour period. In—orbit spares (Flight Models 16—20) also will be launched into Molniya orbits with periods ofapproximately 9.6 hours. One satellite will orbit in each ofthe five orbital planes utilized by the operational satellites. Ifthere is a failure of an operational satellite, the spare orbiting in the same plane will perform an orbital maneuver to change the orbital period to 14.4 hours and to maneuver into the same orbital phase as the failed satellite, to reconstitute full service by the system. In the worst case scenario, the replacement satellite will require 28.8 hours to regjace a failed satellite and an additional 14.4 hour orbital period will be required to stabilize the orbit of the newly—operational spare. The total satellite outage during a worst case will be 43.2 hours, with single service outages of only eight hours in three separate service areas. (3) Sufficient information on the NGSO FSS system characteristics to properly model the system in computer sharing simulations, including, at a minimum, NGSO hand—over and satellite switchingfitrategies, NGSO satellite beam patterns, NGSO satellite antenna patterns and NGSO earth station antenna patterns. In particular, each NGSO FSS applicant must explain the switchingprotocols it used to avoid transmitting while passing through the geostationary satellite orbit arc, or provide an explanation as to how the power—flux density limits in Section 25.208 are met without using geostationary satellite orbit are avoidance. In addition, each NGSO FSS applicant mustprovide the orbitalparameters contained in Section A.3 ofAnnex 1 to Resolution 46. Further, each NGSO FSS applicant mustprovide a sufficient technical showing to demonstrate that the proposed non—geostationary satellite orbit system meets the power—flux density limits contained in Section 25.208, as applicable. Denali‘s original application contained the information requested of this proposed addition to the Commission‘s rules.* The Pentriad system does not require, and Denali does not request, * See sections 3.3 and 4.2 of Denali‘s application, supra note 2. 4

an exclusive allocation of frequency spectrum in the Ku—band. The Pentriad system employs a novel system design that allows for multiple uses of the frequency spectrum. Because of the operational service arc of the satellites, Pentriad can operate, without interference, with satellites in the geostationary/ geosynchronous orbit using the same frequencies in both the Northern and Southern hemispheres coverage areas. The Northern and Southern Hemisphere Orbital Parameters (Exhibit 3) and the Link Budget (Exhibit 4) are appended to the FCC Form 312. Antenna Patterns for the Pentriad System data service are depicted for IOC (Exhibit 5) and FOC & SOC (Exhibit 6), with center position of Washington, D.C., and also appended to the FCC Form 312. (4) A description ofthe design and operational strategies that it will use, ifany, to mitigate orbital debris. Each applicant must submit a casualty risk assessmentifplannedpost— mission disposal involves atmospheric re—entry ofthe spacecraft. The Pentriad System is designed to meet the requirements outlined in the USG Space Debris Mitigation Requirements. The communications payloads ofthe Pentriad design do not involve thé planned release ofany operational debris following the launch phase of operations. Denali also confirms that spacecraft shielding, placement of components, and use of redundant systems has been assessed to limit the probability that an operating spacecraft in the Pentriad system will become a source ofdebris through collisions with man—made objects or meteors. Denali further has assessed and will limit the probability ofaccidental explosion during and after completion of mission operations. The assessment was based on possible failure modes that could result in explosions, and operational procedures will be adopted to limit the probability they will occur. In addition, all sources of stored energy onboard the Pentriad spacecraft will have been depleted or contained in a "safed" mode when no longer required for mission operations or post— mission disposal. Denali has estimated that its Pentriad system design and spacecraft mission profiles will limit the probability of collision with known large objects during the constellation‘s orbital

lifetime. Denali‘s disclosure ofthe parameters (including the number of space stations, the number and inclination of orbital planes, orbital period, apogee, perigee the argument ofperigee, and right ascension ofthe ascending nodes) used by the Pentriad system may assist third parties in identifying potential problems that may be the result of proposed operations, and lends itselfto coordination between Denali and other operators located in similar orbits. Denali will be prepared to disclose the accuracy with which these orbital parameters will be maintained. As a result ofthe perigee ofthe Northern hemisphere Pentriad satellites being over the vast Southern hemisphere oceans, atmospheric reentry is favored for spacecraft disposal at the end of mission life. For the Southern hemisphere satellites, the perigee will be over the northern hemisphere. For these Southern hemisphere satellites, Denali will perform a maneuver out ofthe Mo]n\iya plane that will cause the perigee to precess into the Southern hemisphere, at which time the s;acecrafi will deorbit and enter the atmosphere into the southern oceans. The spacecraft will be designed to eliminate and minimize debris released during normal operations by including sufficient fuel onboard each spacecraft to perform a deorbit burn, thereby hastening reentry and being presented with a risk ofhuman casualty less than 1 in 10,000. Such calculation is predicated on results from the NASA Safety Standard guidance for computing casualty risk." Respectfully submitted, co C A © — By T y Dennis J. Burnett, President David L.
