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.
A laser altimeter is an instrument that measures the distance from an orbiting spacecraft to the surface of the planet or asteroid that the spacecraft is orbiting. The distance is determined by measuring the complete round trip time of a laser pulse from the instrument to the body's surface, and back to the instrument.
Lunar Orbiter Laser Altimeter: LROC: ... 2011, the final set of data from the exploration phase of the mission was released to the NASA Planetary Data System. The ...
NASA Langley created three lidar (light radar) sensors: the flash lidar, Doppler lidar and high-altitude laser altimeter for the ALHAT project. [10] The flash lidar uses imagery technology to detect objects larger than the size of a basketball on a planetary surface under all lighting conditions.
In September 2013, a laser communication system was one of four science instruments launched with the NASA LADEE (Lunar Atmosphere and Dust Environment Explorer) mission. After a month-long transit to the Moon and a 40-day spacecraft checkout, daytime laser communications experiments were performed over three months during late 2013 and early ...
The first, the NASA laser retroreflector array (LRA) reflected laser beams from a network of 10 to 15 ground-based laser ranging stations under clear skies. The second, for all-weather, global tracking, was provided by the CNES Doppler Orbitography and Radiopositioning Integrated by Satellite tracking system receiver . This device uses ...
It operated as an altimeter until a portion of the laser reached end-of-life in June 2001. The instrument then functioned as a radiometer until October 2006.
