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.

Main features

Total precision XY 3 arcsec (1σ)
Residual low frequency error XY1 arcsec (1σ)
Output rate (attitute and covariance)Up to 1Hz
