Introduction : Some History.
Nowadays, the designers of ground based application navigation systems (aircraft, drones, boats, land vehicles, submarines …) need more independence, reliability, redundancy and security. Ground based applications stellar navigation is regaining its interest, and opens up the astral navigation, using the stars, but also the sun, the moon, the planets to provide autonomous, robust and accurate navigation information .
STARNAV is part of this movement by developing optical systems and algorithms that constitute autonomous systems (eg G-Stell electronic sextant) or modules to be integrated into other devices.

The future will find new applications to these techniques that will further push the limits of knowledge: extraterrestrial navigation, measurement of speed in space, …
