![]() ![]() ![]() ![]() ![]() SpectraTRAC’s processing unit, including an advanced star-tracking algorithm, records the accurate measurement of the host spacecraft mission’s position during orbit for optimum real-time attitude determination, and accounts for interference effects of light reflecting from the satellite’s surfaces and exhaust plumes during propulsion sequences. Redwire’s compact and autonomous SpectraTRAC star tracker is ruggedized, radiation tested, optimized for low weight (475 grams, including baffle, and star tracker), small size (120 x 61 x 61 mm), and low power consumption ( 5 years in Low Earth Orbit (LEO). Leveraging its heritage in producing advanced star trackers and compliant with the Buy America Act, Redwire’s low-cost, high-performance SpectraTRAC is a COTS component supporting commercial, civil, and defense missions. When power is applied, the spacecraft begins receiving quarternions accurate to 10 arcsec at 4 Hz rate, and a maximum tracking rate >2° degrees per second. The unit is self-contained and features Lost in Space star identification. The Redwire SpectraTRAC Star Tracker is intended for spaceflight, CubeSat, and NanoSat missions. ![]()
