Abstract

The telemetry data of the sounding rocket when flying in the space is very important to known. This data will be used for next mission or evaluation the last rocket flight. Commonly the data of the sensor in the sounding rocket are accelerometer, gyroscope, magnetometer, GPS. The rocket is required to transmit maximum data to the ground control system when it flies. The problem is when the baud rate is low, there is not much data can be transmitted. Another problem is when using serial bit standard communication such as the baud rate 115200 bps means that the maximum data in one second is 14,400 characters. It is less than when using the PCM bit rate. Application of PCM in the telemetry for sounding rocket LAPAN is new and needs further development to reach the optimal function. The communication data can transmit around 1.25Mbps or 156,250 characters based on the TR FM02-S-2 full Sband transmitter by using PCM method. This research focuses the implementation of PCM method on the FPGA for sending and receiving the data via cable. Two FPGA boards can work together for sending and receiving the data using PCM method with the total bit is 1.25Mbps.
