Payload
Low data rate (LDR) EHF payload is built by TRW and has 192 channels with rates between 75 and 2400 bps. Block 2 spacecraft will carry the LDR in addition to a Medium Data Rate (MDR) payload built by Hughes. The MDR will provide rates of 4800 bps to 1.544 Mbps per channel.
3-axis stabilized. Two large solar arrays.as many as 10,000 users will be able to access the system at any given time.
Other segments of the Milstar antenna suite include two crosslink antennas at the ends of the satellite wings. On the left wing are the helical Ultra High Frequency antennas, two of the three directional spot beam antennas (the third is hidden by the wing structure), and the box-shaped agile beam antennas. The large solar arrays generate power to operate the satellite.Lockheed Martin Space Systems is the prime contractor for theUS$750 million 4537 kg (10,000 lbm) military satellite communications system.The MILSTAR uplink/downlink frequency is 44/20 GHz.
Power (EOL) 5.000 kW
