Summary
ABS-4 (MOBISAT-1), also known as MBSAT, is a communication satellite built by LOR and operated by MBCO/TUMED for the purpose of providing communication services. It was launched on March 13, 2004, from Cape Canaveral Air Force Station's SLC36B launch pad using an Atlas 3A launch vehicle. The spacecraft is based on the SSL-1300 bus and has a configuration identical to its bus type. Its dimensions are 5.6 meters in length, 2.8 meters in diameter, and it spans 31 meters when fully deployed. It carries equipment including 16 S-band transponders, one Ku-band transponder, and a TRW Astromesh 12-meter reflector. The dry mass of the satellite is 2000 kg with an initial launch mass of 4143 kg. Its power system consists of two deployable solar arrays and batteries. ABS-4 was designed to have a lifetime of 12 years.
