Our upgraded fast 3D Mapping Lidar in mission to Antarctica

Sigma Space shipped a second-generation 3D Mapping LiDAR for the University of Texas ice-mapping mission in Antarctica.

Our fast 3D Mapping LiDAR has been upgraded with new high-resolution timing electronics and is being used by University of Texas at Austin to map the ice caps in Antarctica.  The new system is based on Sigma’s highly successful prototype 3D mapping photon-counting LiDAR, previously developed for the US Air Force.  The new timing electronicsimproved the spatial resolution of the LiDAR system while increasing the system’s ability to adjust to varied terrains.  Users were given greater control over system parameters and a near real-time quick look at the data being collected.

Sigma worked with Dynamic Aviation (based in Bridgewater, VA) to fly the new and improved LiDAR system over forested land in Virginia and North Carolina prior to its three-month excursion to Antarctica. The University of Texas researchers will install the LiDAR on a modified DC-3 and they will collect ranging data to build detailed maps of the Antarctic icecap elevation.
