ATLAS instrument assembly at NASA GSFC. The sole instrument on ICESat-2 is the Advanced Topographic Laser Altimeter System (ATLAS), a space-based lidar.It was designed and built at Goddard Space Flight Center, with the laser generation and detection systems provided by Fibertek.
The Advanced Topographic Laser Altimeter System (ATLAS) on NASA's Ice, Cloud, and land Elevation Satellite 2 (ICESat-2) is a photon-counting lidar that uses the return time of laser light pulses from the Earth's surface to calculate altitude of the surface. ICESat-2 measurements can be combined with ship-based sonar data to fill in gaps and ...
All [citation needed] laser rangefinders, laser altimeters and lidar units are derived from the early colidar systems. The first practical terrestrial application of a colidar system was the "Colidar Mark II", a large rifle-like laser rangefinder produced in 1963, which had a range of 11 km and an accuracy of 4.5 m, to be used for military ...

Satellite laser ranging is a proven geodetic technique with significant potential for important contributions to scientific studies of the earth/atmosphere/ocean system. It is the most accurate technique currently available to determine the geocentric position of an Earth satellite, allowing for the precise calibration of radar altimeters and ...
The OSIRIS-REx Laser Altimeter (OLA) is a scanning and lidar instrument that will provide high resolution topographical information throughout the mission. [101] The information received by OLA creates global topographic maps of Bennu, local maps of candidate sample sites, ranging in support of other instruments, and support navigation and ...
The Laser Altimeter could measure the height of the CSM above the lunar surface to within one meter. It used a pulsed ruby laser operating at 694.3 nanometers and 200 millijoule pulses of 10 nanoseconds duration. The Stellar Camera was used during the runs of the Laser Altimeter on the night side of the Moon.
