Automatic Weather Station (AWS) is a system consisting of  sensors, associated field sub-systems and communication equipment, which automatically and continuously measure real time surface weather conditions and sends three times the hourly observed meteorological parameters to the central station through  satellite link in a self timed pseudo random manner in its prescribed 10 minute time slot within the next 60 minutes before the next observation takes place.  Loss of AWS data is due to collision of data burst transmitted simultaneously by any two or more  AWS.  Generally, the  collision of AWS data  burst depends upon the transmission time or transmission baud rate, number of  AWS in a network and total number of bits in  AWS data burst. This paper  describes the influence of  data burst collision on  transmission of  AWS data  through satellite.
