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 ...
This has allowed areas where it is too shallow for most vessels to safely access to be bathymetrically mapped. The potential depth that ICESat-2’s Advanced Topographic Laser Altimeter System (ATLASA) can reach is 38 m in optimum conditions. [13] A magnetometer is an instrument that measures magnetic field or magnetic dipole moment. They are ...
Terrain contour matching, or TERCOM, is a navigation system used primarily by cruise missiles. It uses a contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter. A TERCOM system considerably increases the accuracy of a missile compared with inertial navigation systems (INS). The increased ...

Like its predecessors, the primary instrument aboard Jason-3 is a radar altimeter. Additional instruments include: [16] A microwave radiometer; DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite) A Laser Retroreflector Array (LRA) A Global Positioning System (GPS) receiver
In May 2015, LRO's orbit was altered to fly 20 km (12 mi) above the Moon's south pole, allowing higher resolution data to be obtained from the Lunar Orbiter Laser Altimeter (LOLA) and Diviner instruments over the permanently shadowed craters there. [51] In 2019, LRO found the crash site of Indian moon lander Vikram. [52]
