    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.

  3. Autonomous Landing Hazard Avoidance Technology - Wikipedia

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

    According to the NASA web page on the project, it will provide state-of-the-art automated descent and landing system for planetary lander craft. A surface-tracking sensor suite with real-time hazard avoidance capabilities will assess altitude and velocity of the descending vehicle and the topography of the landing site to permit precision landing.

  5. 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.

  6. Protoflight - Wikipedia

    en.wikipedia.org/wiki/Protoflight

    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.

  8. 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 ...

  9. Satellite laser ranging - Wikipedia

    en.wikipedia.org/wiki/Satellite_laser_ranging

    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 ...
