LIDAR-GNC

PANGU simulated Martian surface

PANGU simulated Martian surface

The LIDAR-GNC research was done as a sub-contractor to EADS Astrium SAS. The aim of this work was to extend PANGU to cover realistic Martian surface generation including boulders and sand dunes and to simulate a scanning LIDAR sensing the Martian terrain. The LIDAR sensor simulation is capable of simulating a range of scanning LIDAR instruments and takes into account spacecraft motion during the scanning interval. PANGU models and the LIDAR simulation have been integrated in a guidance and navigation control system prototype by Astrium.

Examples of false-colour LIDAR range and slope images generated for a PANGU-generated model of Martian terrain are given below.
