Adcole Space Star Tracker

The Adcole Space Star Tracker is a low-cost Star Tracker intended for CubeSat and NanoSat missions. The unit is completely self-contained and features ‘Lost in Space’ star identification. Just apply power and begin receiving quaternions accurate to about 6 arcseconds at 4 Hz rate.

The system has been extensively rate tested and shown to have 96.4% availability of solutions at rates in excess of 2°/sec. The electronics have been radiation tested to 75krad while an optional baffle provides 45° Sun rejection. The Adcole Space Star Tracker is available in either vertical or horizontal mounting.
