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 ...
The Doppler lidar measures the vehicle's altitude and velocity to precisely land on the surface, and the high-altitude laser altimeter provides data enabling the vehicle to land in the chosen area. [10] The lidar laser technology scans an area for hazards like craters or rocks before the lander touches down.

Automated airport weather stations use an upward-pointing laser beam ceilometer to detect the amount and height of clouds. The laser is pointed upward, and the time required for reflected light to return to the station allows for the calculation of the height of the cloud base.
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
A laser altimeter uses the round-trip flight-time of a beam of light at optical or infrared wavelengths to determine the spacecraft's altitude or, conversely, the ground topography. Examples: ICESat , MOLA .
