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 ...
Assuming available laser technology, and considering the divergence of the interferometric signals, the range for satellite-to-satellite communications has been estimated to be approximately 2,000 km (1,200 mi). [83] These estimates are applicable to an array of satellites orbiting the Earth.
The range is a secure lab facility and is a division of the Directed Energy Directorate of the Air Force Research Laboratory. SOR's optical equipment includes a 3.5 meter telescope which is "one of the largest telescopes in the world equipped with adaptive optics designed for satellite tracking" according to the Air Force, a 1.5 meter telescope ...
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 ...
On April 28, 2023, NASA and its partners achieved 200 gigabit per second (Gbit/s) throughput on a space-to-ground optical link between a satellite in orbit and Earth. This was achieved by the TeraByte InfraRed Delivery (TBIRD) system, mounted on NASA's Pathfinder Technology Demonstrator 3 (PTD-3) satellite.
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 ...
In addition to connecting to ground stations to connect to the ground-based internet, satellites will interconnect via optical infrared laser connections. Amazon refers to this technology as OISL (optical inter-satellite link). These lasers are capable of maintaining 100 Gbps over distances up to 2,600 km among two satellites moving at 25,000 km/h.
Starlette (Satellite de taille adaptée avec réflecteurs laser pour les études de la terre, [1] [3] or lit. ' Satellite of suitable size with laser reflectors for studies of the earth ') and Stella are nearly identical French geodetic and geophysical satellites. Starlette was launched on 6 February 1975 and Stella on 26 September 1993.
