Global Positioning System (GPS) is commonly used in terrestrial navigation for vehicle position and velocity knowledge. In the absence of a GPS signal, past landing missions to planetary bodies primarily relied on radar to provide the necessary data to execute descent and landing maneuvers. We have developed a coherent Doppler lidar, called Navigation Doppler Lidar (NDL), that offers several critical advantages com-pared to radar, including significantly higher precision with reduced size, mass, and power.
