ICESat-2 program: PLX vacuum-compatible Lateral Transfer Hollow Retroreflector

All PLX News

ICESat-2 program: PLX vacuum-compatible Lateral Transfer Hollow Retroreflector with a 5” aperture, 18.5” separation and 1 arc second accuracy.

ICESat-2 is NASA’s Ice, Cloud and Land Elevation Satellite scheduled for launch in 2017. The mission of the satellite is to deploy a spaceborne sensor to collect altimetry data of the Earth’s surface optimized to measure ice sheet elevation change and sea ice thickness, while generating an estimate of global vegetation biomass.

The sole instrument on ICESat-2 will be the Advanced Topographic Laser Altimeter System or ATLAS. The ATLAS laser will emit visible, green laser at a wavelength of 532nm. AS ICESat-2 orbits, ATLAS will split the laser into 6 beams, arranged in 3 pairs, with 3.3km between pairs. It will fire at a rate of 10kHz - 10,000 times per second.

PLX manufactured a vacuum-compatible Lateral Transfer Hollow Retroreflector with a 5” aperture, 18.5” separation and 1 arc second accuracy for the ICESat-2 program. It will be used for boresighting and performance testing of ATLAS.
