A global message network employing low Earth-orbiting satellites
IEEE Journal on Selected Areas in Communications, 1992A global message communication network for low-density traffic, using satellites at low altitudes, is described. This network affords around-the-clock service to any part of the globe, including the polar regions. Such a network can accommodate static and mobile user terminals simultaneously.

Communications By Means Of Low Earth Orbiting Satellites
1996Abstract Many organizations have proposed satellite-based personal communications providing global coverage for voice and data to hand-held subscriber units with a direct link to a satellite. Such systems will offer the ultimate promise of personal communications of allowing communications to the personat any time and in any place ...

Ground Station for Low Earth Orbit Satellites
2022Ground stations are essential for satellite operations as they are used to send commands to satellites, receive the satellite telemetry information and payload data. We constructed a ground station for UHF and VHF band two-way communication with low Earth orbit satellites and prepared for installation an X-band downlink ground station.

Probabilistic routing protocol for low Earth orbit satellite networks
ICC '98. 1998 IEEE International Conference on Communications. Conference Record. Affiliated with SUPERCOMM'98 (Cat. No.98CH36220), 2002Low Earth orbit (LEO) satellite networks have dynamic, yet deterministic, topologies. The time-varying connectivity pattern would result in the re-routing of all connections passing through a link that is turned off as a result of the topology change. A routing algorithm called probabilistic routing protocol (PRP) is introduced.

COMMUNICATIONS DURATION WITH LOW EARTH ORBITING SATELLITES
2007Communication via satellite begins when the satellite is positioned in the desired orbital position. The satellite’ s coverage area on the Earth depends on orbital parameters. Ground stations can communicate with LEO (Low Earth Orbiting) satellites only when the satellite is in their visibility region.

Low Earth Orbit Satellite Radio Networks
1997A global phone company may sound a curious statement in an industry still dominated by state-owned monopolies which mainly work within their national borders. But it is a concept whose time has come as, practically everywhere, governments either privatize or think of privatizing and deregulating their phone markets.
