Need Help Choosing?
A daytime star tracker for GNSS-denied navigation
When combined with an Inertial Measurement Unit (IMU), Astradia delivers day- and night-time attitude measurements, thanks to the stars.
Accurate and robust navigation
Specially designed for aircraft, Astradia coupled with an IMU is autonomous. It aims to counter the natural drift in inertial navigation systems.
A compact design
Astradia’s design, compact and single-box, makes it easily integrable on a wide range of carriers.
Dual-use equipment
Astradia is a dual-use equipment that can address military and civil applications.
