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 ...
Techniques of satellite geodesy may be classified by instrument platform: A satellite may be observed with ground-based instruments (Earth-to-space-methods), carry an instrument or sensor as part of its payload to observe the Earth (space-to-Earth methods), or use its instruments to track or be tracked by another satellite (space-to-space methods).
In November 2013, laser communication from a jet platform Tornado was successfully demonstrated for the first time. A laser terminal of the German company Mynaric (formerly ViaLight Communications) was used to transmit data at a rate of 1 Gbit/s over a distance of 60 km and at a flight speed of 800 km/h in daylight. Additional challenges in ...
Carved out from Japanese satellite giant SKY Perfect JSAT this year, Orbital Lasers is building a system that will use laser energy to stop the rotation of space junk by vaporising small parts of ...

LAGEOS (/ l eɪ ʒ iː oʊ s /), Laser Geodynamics Satellite or Laser Geometric Environmental Observation Survey, are a series of two scientific research satellites designed to provide an orbiting laser ranging benchmark for geodynamical studies of the Earth. Each satellite is a high-density passive laser reflector in a very stable medium Earth ...
The laser array is rotated 2 degrees from the satellite's ground track so that a beam pair track is separated by about 90 m (300 ft). The laser pulse rate combined with satellite speed results in ATLAS taking an elevation measurement every 70 cm (28 in) along the satellite's ground path. [17] [19] [20] The laser fires at a rate of 10 kHz.
SpaceX's thousands of Starlink satellites in low-Earth orbit use inter-satellite laser links to pass data between one another in space at the speed of light, allowing the network to offer broader ...
