Link Budget Analisys Of National Payload Rocket Telemetry Competitionin Pamengpeuk Garut West Java

Communication system on telemetry payload rocket competition has been built in order to transfer data between payload and the ground station. The transmitter and receiver frequencies were set up into 432.0325MHZ, 433.0325 MHZ, 434.0325 MHZ, and 435.0325 MHZ with their 20 dBmoutput power. Link budget analysis of this system show that the system would have 33 km maximum distance communication with the link margin value was 18 dB which 99% communication availability. It is quite enough for payload rocket competition at PamengpeukGarut West Java due to trajectory rocket predicted only as far as 1 km or below.
