Satellites in Non-Geostationary Orbits

1993
This Chapter examines recent trends towards the use of communications satellites in low earth orbits and in other non-geostationary orbits. It is shown why the use of such orbits could offer the possibility of satellite communications from miniature hand-held earth terminals. The various classes of non-geostationary orbits are first described.

Geostationary operational environmental satellite /GOES/ - A multifunctional satellite

9th Communications Satellite System Conference, 1982
The GOES satellites are multifunctional satellites whose primary function is to provide continuous measurements of the earth's surface and atmosphere from two geostationary orbit locations: 75 deg W and 135 deg W. This objective is accomplished with the visible infrared spin scan radiometer Atmospheric Sounder (VAS), and the Space Environment Monitor ...

Non-Geostationary Orbit Satellite Systems

1999
Until the late 1980s, satellites in non-geostationary orbit had limited use for communication applications because, in general, these systems are more complex and, since geostationary satellites met most requirements anyway, not much effort was spent on their development.

Performance of Satellite Gateway over Geostationary Satellite Links

MILCOM 2013 - 2013 IEEE Military Communications Conference, 2013
A significant amount of today's Internet traffic, including World Wide Web (WWW), file transfer, e-mail and remote access traffic, is carried by the Transmission Control Protocol (TCP) transport protocol. Geostationary satellite links have a number of features that may degrade the performance of the TCP over them.
