The INTELSAT-K spacecraft is a GE/Martin Marietta Series 5000 three-axis-stabilized platform equipped with four 22-cell, 50-Ah batteries and capable of providing 3.5 kW of solar array power after 10 years in orbit. The main spacecraft body contains the central cylinder, propulsion tanks, and thrusters. The thrusters include twin 490-N, dual-mode, liquid apogee engines and four improved electrothermal hydrazine thrusters for attitude control. The spacecraft mass at liftoff was 2,925 kg, with a dry weight of 1,250 kg. The general design characteristics of INTELSAT-K are described, with emphasis on spacecraft bus capabilities as they relate to the in-orbit operations of the satellite.
