GEOSTATIONARY OPERATIONAL ENVIRONMENTAL SATELLITE (GOES) Telemetry and Communications
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: 75EW and 135EW. This objective is accomplished with the Visible infrared spin scan radiometer Atmospheric Sounder (VAS). The atmospheric sounder is a new feature which will add a third dimension to the photo...
متن کاملTcp Performance in a Geostationary Satellite Environment
Geostationary satellite links have characteristics that can degrade the performance of TCP. The propagation time for a geostationary satellite link is on the order of 0.25 seconds. Thus a satellite can add approximately 0.5 seconds to the round trip time experienced by a TCP packet and the corresponding acknowledgement. This delay time is the primary cause of TCP inefficiency over satellites. T...
