Status: Operational 1999. First Launch: 1999-03-28. Last Launch: 2015-10-02. Number: 38 . Gross mass: 5,200 kg (11,400 lb).

After the payload was tailored to customer specifications, the payload module mounted to the common bus module at only four locations and with only six electrical connectors. This design simplicity conferred major advantages. First, non-recurring program costs were reduced, because the bus did not need to be changed for every payload, and payloads could be freely tailored without affecting the bus. Second, the design permitted significantly faster parallel bus and payload processing. This led to the third advantage: a short production schedule.

Further efficiency derived from the HS 702's xenon ion propulsion system (XIPS), which Hughes pioneered. XIPS was 10 times more efficient than the conventional liquid fuel systems. Four 25-cm thrusters provided economical station-keeping, needing only 5 kg of fuel per year. Using XIPS for final orbit insertion conserved even more mass. Customers could apply the weight savings to substantially increase the revenue-generating payload at small marginal cost, to prolong service life, or to change to a less expensive launch vehicle (where cost was based on satellite weight).

The HS 702 also incorporated a bipropellant propulsion system, which could lift the satellite into final orbit after separation from the launch vehicle. The bipropellant system had a fuel capacity of 1750 kg. Multiple major payloads or missions could fly on the same spacecraft. Also, customers could share the 1200-kg payload capacity with other customers, reducing launch and ground station operating costs for each participant.

The spacecraft was adaptable to medium earth and geostationary orbits. Innovative modularity extended to the HS 702 power system as well. A catalogue of standard configurations offered six different solar array arrangements, with up to five panels of solar cells per wing. As a new feature on the HS 702, angled solar reflector panels along both sides of the wings formed a shallow trough and concentrated the sun's rays on the solar cells. At the end of life, the arrays generate up to 15 kW, depending on customer payload selections. The Hughes-proprietary dual-junction gallium arsenide solar cells supplied twice the power of silicon cells at end of life. The cells were developed by Spectrolab, a Hughes Electronics Corporation subsidiary. The integrated power controller, which controlled and distributed electrical power from the solar arrays to the spacecraft, was also modular so it could be matched to the required power level. Finally, for sustained power during eclipses, the nickel-hydrogen battery comprised two kinds of cells at two power ranges, available in multiple configurations of up to 60 cells distributed in four packs.

Separating the bus and payload thermal environments and substantially enlarging the heat radiators achieved a cooler, more stable thermal environment for both bus and payload. This increased unit reliability over service life. The deployable radiators used flexible heat pipes, which increased the packageable radiator area. Further thermal control occurred through passive primary rejection via heat pipes. The HS 702 could accommodate east-west mounted antennas up to 9 feet, 4 inches in diameter, as well as a generous earth-facing array. Viewed from above, the HS 702 was rectangular. This shape left more room in a circular fairing for stowing antennas than a square spacecraft would. The additional space on the east and west sides could be used for large-aperture (and hence high-gain) antennas in various configurations. This space also enabled the antennas to retain simple, reliable, single-axis deployments.

The baseline HS 702 was compatible with all available launch vehicles. These included the Atlas II family, Delta III, Ariane 4 and 5, Long March 3B, Proton, Sea Launch, and H-II. Some customer choices affect launch vehicle options. For example, selecting a maximum-power HS 702 configuration could increase spacecraft mass and height (the extra heat dissipation equipment needed makes the satellite slightly taller), dictating use of a larger launch vehicle.

Deployed length 40.9 m maximum Payload mass up to 1200 kg. Launch mass up to 5200 kg. Stowed width, including solar panels 2.0 x 3.2 m. Stowed height (bus and payload, excluding nadir antennas) 3.6 m.

The first customer for the HS 702 was Hughes Communications, Inc., which merged with PanAmSat Corporation in May 1997 to create the world's largest privately owned communications satellite company. The HS 702 was chosen for the Galaxy and PAS fleet, to expand video distribution, telephony, and data services in North and Latin America. As of March 1999, Hughes had received orders for nine of these spacecraft: three from PanAmSat Corporation, two from XM Satellite Radio, Inc., one from Telesat Canada, and three for Spaceway..

Major problems in orbit with the solar-concentrator power generation option led to abandonment of this feature in later versions of the bus.

  The XM Radio satellites (using Boeing 702 buses) provided digital radio entertainment broadcast to the US. The XM-2 Rock satellite was accompanied by the XM-1 Roll spacecraft launched later in 2001. A Boeing Sea Launch Zenit-3SL took off from the Odyssey floating launch platform at 154W 0 N in the Pacific. The two-stage Zenit put the Blok DM in a suborbital trajectory with a 190 km apogee; the DM first burn went to a 180 x 990 km x 1.3 deg orbit, with the second burn delivering Rock to geostationary transfer orbit.

It carried an R-4D liquid apogee engine and a XIPS ion station-keeping engine. The satellite's Alcatel communications payload featured an X-band receive antenna which passed digital radio broadcasts on to the two 5-meter S-band transmit antennas. It was to provide one hundred channels of digital music and entertainment to motorists in North America after parking over 85 deg-W. The XM satellites, like the three rival Sirius Radio satellites in inclined elliptical synchronous orbits, were to provide radio broadcasting to North America. The first two stages of the Zenit launch vehicle placed the Block DM-SL upper stage and payload in a 191 km apogee suborbital trajectory at 2219 GMT; the Block-DM-SL then ignited for its first burn, entering a 180 x 990 km x 1.3 deg parking orbit at 2223 GMT. The second burn at 2258 GMT accelerated the stack to a 935 x 35797 km x 1.3 deg geostationary transfer orbit. The XM-1 Roll satellite separated at 2315 GMT. As of 5 September 2001 located at 85.12 deg W drifting at 0.009 deg W per day. As of 2007 Mar 10 located at 115.09W drifting at 0.002W degrees per day.

The Zenit second stage and the DM third stage with payload entered a -2160 x 195 km suborbital trajectory at 2248:10. At about 2252 UTC the DM stage entered a 180 x 393 km x 0 deg parking orbit. A second burn of the DM at 2324 to 2330 UTC put Galaxy 3C in a 358 x 41440 km x 0.02 deg transfer orbit This was a record low inclination for a geostationary transfer orbit. The satellite's R-4D apogee engine was to put the Boeing BSS-702 satellite in geostationary orbit. The satellite was the first 702 model to use extra solar panels instead of the solar concentrators which ran into fogging problems on the earlier 702 flights.

  The platform was designed to survive such an explosion, but the flame deflector was blown off and the blast doors unhinged. The launch platform was towed back to Long Beach for repairs. The time required to repair the platform and the investigation to determine and fix the cause would certainly impact the 2007 Zenit-3SL and Zenit-2 launch schedules, probably forcing customers to be diverted to other boosters. NSS-8 was to have been placed at a 57º East orbital position to satisfy demand in the Indian Ocean region with 56 C-band and 36 Ku-band transponders. NSS-703, with an expected end-of-life in 2009, would have to continue in service until a replacement was built and launched.
