Abstract :
The communication antennas of the ARABSAT spacecraft are described, and problems associated with antenna spacecraft integration are discussed. The payload consists of 25 C/C band transponders providing 8000 simultaneous telephone circuits plus seven TV programs or an equivalent traffic in other kinds of fixed services, and one C/S transponder for semidirect television. EIRP (equivalent isotropically radiated power) performances are 31 dBW in C-band and 41 dBW in S-band, while G/T corresponds to -7.5 dBK over the specified coverage.<>
