Satellite laser ranging (SLR) is a method to measure the distance to satellites in a geocentric orbit. It consists of an astronomical observatory equipped with a laser that sends ultrashort pulses of light. The pulses hit the satellite and bounce back to be caught by the station, which measure the round trip time with the speed of light formula ...
The first successful laser-communication link from space was carried out by Japan in 1995 between the NASDA's ETS-VI GEO satellite and the 1.5 m (4 ft 11 in) National Institute of Information and Communications Technology (NICT)'s optical ground station in Tokyo achieving 1 Mbit/s. [5]
The technology demonstration payload will be positioned above the equator, a prime location for line-of-sight to other orbiting satellites and ground stations. Space laser communications technology has the potential to provide 10 to 100 times higher data rates than traditional radio frequency systems for the same mass and power. Alternatively ...
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 ...
Long-range optical wireless communication or free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking over long distances. "Free space" means air, outer space, vacuum, or something similar.
All Galileo satellites are equipped with laser retroreflector arrays which allow them to be tracked by the stations of the International Laser Ranging Service. [176] Satellite laser ranging to Galileo satellites are used for the validation of satellite orbits, [177] determination of Earth rotation parameters [178] and for the combined solutions ...
Deep Space Optical Communications (DSOC) is a laser space communication system in operation that improved communications performance 10 to 100 times over radio frequency technology without incurring increases in mass, volume or power. [1] DSOC is capable of providing high bandwidth downlinks from beyond cislunar space.
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 ...
