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 sole instrument on ICESat was the Geoscience Laser Altimeter System (GLAS), a space-based lidar. GLAS combined a precision surface lidar with a sensitive dual-wavelength cloud and aerosol lidar. The GLAS lasers emit infrared and visible laser pulses at 1064- and 532-nm wavelengths.
The laser pulse can also be reflected by the surface of a satellite without a retroreflector, which is used for tracking space debris. [1] 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 ...
The Lunar Orbiter Laser Altimeter investigation provides a precise global lunar topographic model and geodetic grid. Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) The Lunar Reconnaissance Orbiter Camera addresses the measurement requirements of landing site certification and polar illumination.

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 .
The Cassini radar was a multimode system and could operate as Synthetic Aperture Radar, radar altimeter, scatterometer and radiometer. Sounding radars: these are low-frequency (normally, HF - 3 to 30 MHz - or lower) ground-penetrating Radars, used to acquire data about the planet sub-surface structure. Their low operating frequency allow them ...
As defined by NASA Technical Standard NASA-STD-7002A, [1] it refers to a strategy where no test-dedicated qualification article exists and all production (flight) hardware is intended for flight. An example of a program using protoflight methods is the Mars Orbiter Laser Altimeter project.
The Laser Communications Relay Demonstration (LCRD) is a NASA mission that will test laser communication in space for extremely long distances, [1] between Earth and geosynchronous orbit. After being integrated into STPSat-6 , a part of STP-3 , LCRD launched on 7 December 2021 on an Atlas V 551.
