The compact High Speed Scanning Lidar (HSSL) was designed to meet the requirements for a rover GN&C sensor. The
eye-safe HSSL's fast scanning speed, low volume and low power, make it the ideal choice for a variety of real-time and
non-real-time applications including:
Vehicle guidance and Navigation;
Spacecraft Landing / Hazard Avoidance.
The HSSL comprises two main hardware units: Sensor Head and Control Unit. In a rover application, the Sensor Head
mounts on the top of the rover while the Control Unit can be mounted on the rover deck or within its avionics bay. An
Operator Computer is used to command the lidar and immediately display the acquired scan data.
The innovative lidar design concept was a result of an extensive trade study conducted during the initial phase of an
exploration rover program. The lidar utilizes an innovative scanner coupled with a compact fiber laser and high-speed
timing electronics. Compared to existing compact lidar systems, distinguishing features of the HSSL include its high
accuracy, high resolution, high refresh rate and large field of view. Other benefits of this design include the capability to
quickly configure scan settings to fit various operational modes.
