The Redwire SpectraTRAC Star Tracker is intended for spaceflight, CubeSat, and NanoSat missions. The unit is self-contained and features Lost in Space star identification. 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. 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.

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 (< 2.5W) with a design life > 5 years in Low Earth Orbit (LEO).

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.

While 50-60 main navigational stars are primarily used to determine a satellite's position, the minimum number of catalog stars visible in any stationary image of arbitrary attitude (free of Earth, Sun, or Moon blockage) will be at least 7 and more typically 10 or 11 stars.

High Resolution Star Trackers are export controlled through an ECCN (Export Control Classification Number) issued by the United States Department of Commerce. Export shipment requires successful application for an export license (under ECCN7A004 for Redwire SpectraCAM Flight Cameras). Redwire is AS9100D/ISO 9001 certified.
