The LIDAR-LAPS research is being undertaken as a sub-contractor to EADS Astrium SAS. The aim of this work is to extend PANGU scanning LIDAR sensor to support a different type of scanning pattern from the LIDAR-GNC and LIDAR-ILT projects. The LAPS system consists of a laser which emits pulses every 100 μs asynchronously to two oscillating mirrors controlling the beam direction in azimuth and elevation. The two mirrors scan the field of view driven by independent triangle waves. As with the LIDAR-GNC and LIDAR-ILT projects, the sensor simulation takes into account spacecraft motion during the scanning interval.
