About
Upgraded from the NST4S-A2, the NST5S-A1 is an autonomous, high-precision and compact-sized star tracker with a Sun Exclusive Angle of 35 degrees, allowing it to operate closer to the Sun in the field of view than its predecessor. It targets small satellite platforms needing high-accuracy attitude determination in a compact envelope, with low power consumption and standard RS422/CAN data interfaces.
