Celestial NAV

Celestial-NAV is a pure rust library that aims at providing celestial navigation by means of stars image analysis. It is intended for work in close relationship with a navigation framework, an IMU sensor and a camera sensor.

no-std

The library works without std. The idea is to augment a navigation framework on an embedded platform.

Input

Celestial-NAV works from two inputs:

• a frame picture of (X, Y) dimensions
• the rover attitude (or state vector)
• both need to be regularly updated

Core algorithm

Celestial-NAV extracts the star (x, y) coordinates in the camera frame and project them into 3D.

Dependencies

Celestial-nav depends on the following key elements:

• geo for 2D coordinates
• nalgebra: solver
• hifitime: timing
