  2. ICESat-2 - Wikipedia

    en.wikipedia.org/wiki/ICESat-2

    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.

    en.wikipedia.org/wiki/Underwater_exploration

    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 ...

  4. ICESat - Wikipedia

    en.wikipedia.org/wiki/ICESat

    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.

  5. Bathymetry - Wikipedia

    en.wikipedia.org/wiki/Bathymetry

    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 ...

  7. Autonomous Landing Hazard Avoidance Technology - Wikipedia

    en.wikipedia.org/wiki/Autonomous_Landing_Hazard...

    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.

  8. Satellite geodesy - Wikipedia

    en.wikipedia.org/wiki/Satellite_geodesy

    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 .

  9. Lunar Reconnaissance Orbiter - Wikipedia

    en.wikipedia.org/wiki/Lunar_Reconnaissance_Orbiter

    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]
