The objective is to perform a pre-development of a star tracker on a chip and get a proof-of-concept.

The Sensor on a chip activity has shown the feasibility of a 75g, 0.2 watt, 30 arcsecond accuracy fully autonomous star tracker with all functionality implemented on a single chip. Several key unknowns however still exist and can only be verified by test.These include: Optical quality achievable, on chip NVM behavious, radiation behaviour of key functions, noise cross talk and power management. Phase 0 of this predevelopment shall concentrate on demonstrating the optical elements including bonding to the silicon substrate and environmental testing.
