Physical Sciences Inc. (PSI) has been awarded a contract from NASA to develop a low size, weight, power, and cost (SWaP-C) terrain mapping sensor solution that is applicable to onboard hazard detection and avoidance for safe and precise landing.
PSI is proposing an Adaptive Sampling (AdS) LiDAR for high-speed, high-resolution hazard detection capable of generating digital elevation maps (DEMs) for entry/deorbit, descent, and landing. This system will function as a standalone 3D terrain mapping sensor, mapping from altitudes over 250 m, that can be generalized to various missions and platforms regardless of illumination condition. The AdS-LiDAR uses a highly flexible receiver architecture that allows it to generate DEMs at high speeds (< 4 seconds) with high resolution (1000 x 1000 pixels) without scanning. In the Phase I program, we will build and functionally test an AdS-LiDAR breadboard, demonstrating ranging and mapping capabilities.
