The
4027 kg (8876 lbm) direct broadcast satellite was built by
Lockheed Martin using the A2100AX spacecraft bus. Echostar 7
carries 32 Ku-band transponders capable of operating at 120 watts
per channel, which are switchable to 16 transponders capable of
operating at 240 watts per channel. Five transponder frequencies
may also be used in a spot beam mode for a potential total of 15
spot beams.
EchoStar 7 will replace
EchoStar 4, which has experienced a series of anomalies impacting its
performance.
