O.C.E. Technology's (OCE) autonomous star trackers are used for accurate attitude determination. More than 100 star trackers are in commission on satellites such as NS-1/2 and the JILIN-1 group. The majority of these satellites are earth observation providing video and high resolution remote sensing data.

Features include:

• Integrated mechanical design with small size
• SOC (system on a chip) based electrical design
• Radiation-hardened
• Flexible-rigid PCB for reliability and isolation of outside connection from the sensitive board for accuracy
• Small baffle design with ultra-black material
