  • ALSAT-1 - . Mass: 80 kg (176 lb). Nation: Algeria. Agency: NCST. Manufacturer: Surrey. Program: Alsat. Class: Surveillance. Type: Civilian surveillance satellite. Spacecraft: MicroSat-100. USAF Sat Cat: 27559 . COSPAR: 2002-054A. Apogee: 745 km (462 mi). Perigee: 681 km (423 mi). Inclination: 98.2000 deg. Period: 99.00 min. Delayed from September 12, October 29. ALSAT 1 was an Algerian imaging minisatellite. The 90-kg satellite was the first part of an international Disaster Monitoring System (DMS) for alerting natural/man-made disasters. ALSAT was built by Surrey Satellite for the CNTS (Centre National des Techniques Spatiales) in Algiers. It carriee a 32-m resolution 3-band imager, a 100 mN resistojet thruster for small orbit corrections, and a GPS receiver. The SSTL Microsat-100 class satellite was a 0.60m cube with a 6m gravity gradient boom. As well as gravity gradient stabilization, it used a momentum wheel to improve stability for imaging.
