Influence of data burst collision on PRBS transmission through satellite

An automatic weather station (AWS) or data collection platform (DCP) is a rugged, environmentally qualified system of sensors, computers and communication equipment, which automatically and continuously measures real time surface weather conditions and three times hourly sends the observed meteorological parameters to the central station through a satellite link in a self-timed pseudo random manner in its prescribed 10 minute time slot within the 60 minutes before the next observation takes place. Loss of AWS data is due to the collision of data bursts transmitted simultaneously by any two or more AWS. Generally, the collision of AWS data bursts depends upon the transmission time or transmission baud rate, number of AWS in a network, and total number of bits in the AWS data burst. This paper describes the influence of data burst collisions on pseudo random burst sequence (PRBS) transmission through satellite.
