Description
The Advanced Research and Global Observation Satellite (ARGOS) is the largest (6000 lb.) Air Force Research and Development (R&D) satellite ever to fly. The mission responds to the periodic need to fly large, heavy, or high power R&D payloads. The Space Vehicle pioneers a number of innovations in advanced space systems, providing operational support for eight DoD experiments, which themselves are demonstrating a number of advancements in space hardware. ARGOS innovations include integration of low risk advanced features such as a radiation hardened flight computer, the first complete GPS receiver embedded within the flight computer for position determination and time reference, and an extremely accurate attitude determination and control system. In addition, ARGOS uses scaled up solid-state recorder, mass storage to provide 2.6 Gigabits of onboard data storage. This is the first space vehicle which combines such accurate positioning and pointing with abundant storage/retrieval capabilities for a suite of imaging sensors. Other ARGOS innovations include: four 15.5” high-angular-momentum reaction wheels - the largest to be flown to date; a next generation nickel hydrogen (NiH2) battery rated at 45 A-hr; advanced technology Ring Laser Gyros, 40°/0 the size of standard RLGs, and High Output Paraffin (HOP) thermal actuators for payload deployment- significantly reducing unique circuitry while satisfying stringent range safety requirements.
