Daytime Star Trackers
Capable of supporting navigation systems independently of GPS, daytime star trackers offer an alternative to satellite positioning systems, which can be vulnerable to jamming or spoofing.
When combined with an inertial navigation unit, the daytime star tracker delivers accurate, reliable, and discreet attitude measurements, both during the day and at night, without emitting detectable signals.
