An experimental evaluations of nanosatellite transmitter and receiver systems for telemetry application

A transmitter and receiver system for telemetry purpose and to be mounted on a nanosatellite, is assembled. The prototype consists of a sensor BMP085 (temperature sensors , barometric pressure and altitude), Arduino Mega 2560 microcontroller modules , XBee Pro S2B modules and servo motors. A receiver module and XBee S2B computer as a media viewer are the main parts of the receiver. A performance test is conducted in LOS and NLOS condition. From the test, it was concluded that the prototype has a communication range of 63,24 meters and 58,52 meter for LOS and NLOS condition respectively. Validation of the sensor measurement has yield a low error percentage for temperature measurement (3.27%) and for air pressure measurement (0,69%).
