EchoStar 3 was originaly ordered as DBSC 1 by DBSC (Direct Broadcast Satellite Corporation) which merged with a subsidiary of EchoStar in late 1995. The merger was approved by the FCC in August 1996. EchoStar is only authorized to operate 11 transponders from 61.5°W but was granted in Mar 1998 a special authorization to use the full frequency space at that location.
Geostationary OrbitIRS 1C and 1D (Indian Remote Sensing Satellite) were the second version of the series of indigenous state-of-art remote sensing satellites. Skipper was an international project initiated by BMDO to measure the bow-shock UV emissions from reentering bodies at different speeds and heights.
Low Earth OrbitIridium provides global mobile telecommunications services using a constellation of 66 low earth orbit satellites in a 86.4° inclined orbit. Although 77 satellites were originally envisioned for the system and spawned the name based on the 77th element in the periodic table, the system has been scaled back. Motorola's Satellite Communications Group designed and manufactured the Iridium satellites with Lockheed Martin providing the LM-700A spacecraft buses.
Low Earth OrbitThe Intelsat VIII-VIII/A series has been designed to meet the needs of Intelsat users throughout the system for improved C-band coverage and service. These spacecraft will incorporate six-fold C-band frequency reuse, two-fold frequency reuse of expanded C-band capacity, and the highest C-band power level ever for an Intelsat satellite. Consequently, Intelsat VIII will provide significantly more C-band capacity for public switched telephony and Intelsat Business Service, better quality for video services, and encourage new international VSAT applications.
