  2. ICESat-2 - Wikipedia

    en.wikipedia.org/wiki/ICESat-2

    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.

  3. 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 ...

    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 ...

  7. Satellite laser ranging - Wikipedia

    en.wikipedia.org/wiki/Satellite_laser_ranging

    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 ...

  8. Satellite geodesy - Wikipedia

    en.wikipedia.org/wiki/Satellite_geodesy

    The two different wavelengths of radio waves used permit the altimeter to automatically correct for varying delays in the ionosphere. Spaceborne radar altimeters have proven to be superb tools for mapping ocean-surface topography, the hills and valleys of the sea surface. These instruments send a microwave pulse to the ocean's surface and ...
