The Analysis of LAPAN-A3/IPB Satellite Image Data Simulation Using High Data Rate Modem

LAPAN-A3/IPB is one of the satellite development programs from National Institute of Aeronautics and Space (Lapan) Indonesia which was designed for specific experimental mission such as remote sensing, marine and fisheries research, land cover and shipping monitoring using AIS as well, that were needed to observe the Indonesian territory. In order to simulate LAPAN-A3/IPB line imager data acquisition using high data rate modulator and demodulator (HDRM), it is required two independent simulation program. The background behind that was the data rate constraint. It took a large amount of CPU resources to simulate 105 Mbps CCSDS packet data formation. So the simulation was divided into two parts, the first part will simulate the 5 mbps CCSDS packet data formation and the second will simulate the 105 mbps pseudo random binary sequence (PRBS). This four channel payload of R,G,B and Ni system of LAPAN-A3/IPB satellite is quite similar with Landsat camera standard as an earth observation satellite. This paper will describe about the modulation and demodulation simulation process of the LAPAN-A3/IPB satellite data image by using HDRM
