Optical System in Laser Inter-Satellites Communication
2008 International Conference on Computer Science and Information Technology, 2008We know that Inter-satellites communication is a very important to us. However, real global coverage can only be achieved by satellite systems. Satellites communication is the most important mean of the communication network. The traditional satellites communication and inter-satellites links are built by microwave.

Laser Satellite Communication Systems
2009Overview: In this chapter we consider statistical quantities introduced in Chaps. 6-9 and adapt them to vertical and slant path propagation links. Most of the analysis presented here is for a slant path connecting a satellite in geostationary orbit and a ground or airborne platform.

Laser communications utilizing Molniya satellite orbits
SPIE Proceedings, 2004The Molniya orbit can be exploited for communications using laser technology. Since the Molniya orbit repeats, exactly, every 24 hours, such a system will allow high latitude and ground based lasers to use Molniya satellite links much the same way that equatorial located lasers can use geostationary satellites.

M diversity for reliable laser satellite communication
Free-Space Laser Communications XXXIII, 2021Infrared satellite links are examined to measure earth surface temperatures. The low earth orbits would offer low cost and Brandon orbits would offer the convenience of stationary ground antennas. A square array of ground stations is considered (‘Quad Diversity’) to relieve laser attenuation, and higher order diversity is considered.

Design and analysis of the satellite laser communications network
SPIE Proceedings, 2015A satellite laser communications network structure with two layers and multiple domains has been proposed, which performance has been simulated by OPENT. To simulation, we design several OPNET models of the network’s components based on a satellite constellation with two layers and multiple domains, as network model, node model, MAC layer protocol and ...

Optical antenna in laser inter-satellite communication
SPIE Proceedings, 2005In the modern world of telecommunications, the concept of wireless global coverage is of the utmost importance. However, real global coverage can only be achieved by satellite systems. Satellites communication is the most important mean of the communication network.

Laser Communications Airborne Testbed: Potential For An Air-To-Satellite Laser Communications Link
SPIE Proceedings, 1988The Laser Communications Airborne Testbed (LCAT) offers an excellent opportunity for testing of an air-to-satellite laser communications link with the NASA Advanced Communications Technology Satellite (ACTS). The direct detection laser portion of the ACTS is suitable for examining the feasibility of an airborne terminal.

Diversity Effects in Satellite-Ground Laser Communications Using Satellite Images
29th AIAA International Communications Satellite Systems Conference (ICSSC-2011), 2011The sites selection of optical ground stations (OGSs) in satellite-ground laser communications and the effects applied two types of diversity schemes are examined quantitatively. The existence of interception of the laser beam by clouds, which causes communication quality degradation is judged using the dot values of meteorological satellite images ...

Secret key agreement for satellite laser communications
2021Free-space optical (FSO) communications offer high-capacity wireless transmission due to their plentiful properties originated from higher carrier frequency. These properties also yield a greater security advantage: the high directionality of the laser beam and the line-of-sight configuration can reasonably restrict an attack model launched by an ...
