A Low-Cost Multi-Camera Star Tracker for Small Satellites

Researchers from the University of Illinois have developed an accurate, low-cost star tracker system for deployment in small satellites. The system combines multiple low-cost image sensors with proprietary software to achieve superior performance from a simple, lightweight star tracking solution. With its easy implementation and component costs at just hundreds of dollars, this device can dramatically increase the accessibility of quality attitude determination for CubeSat, NanoSat, and other missions. The star tracker may also be adapted as a positioning system for select terrestrial vehicles that would benefit from greater security and reliability than conventional GPS.


A cheaper, and more compact method to make star trackers for satellites.

Easier to make than current methods which makes the tracker more broadly applicable for different satellites. 

Market Application

Best used for CubeSats which have difficulties determining their orientation
