UOSAT 12

NSSDCA/COSPAR ID: 1999-021A

Description

UoSAT 12 was launched from the Baikonur cosmodrome by ISC Kosmotras aboard the first orbital demonstration launch of the SS-18 Dnepr vehicle. Surrey Satellite Technology Ltd (SSTL) built the satellite to validate key minisatellite bus and payload technologies. The mission enabled SSTL to offer flight-proven minisatellite solutions for commercial, scientific, military and know-how transfer programs. UoSAT 12 carried payloads for multi-spectral and panchromatic Earth imaging; experimental S-band/L-band communications; and operational VHF / UHF store-and-forward messaging. In addition to these payloads, UoSAT 12 demonstrated Surrey's new minisatellite bus subsystems, including GPS orbit and attitude determination; cold-gas orbit and attitude control; nitrous oxide resistojet orbit control; star imagers; reaction wheels; Ethernet LAN; and 28-V power system.
