The RazakSAT^® IRPS has three main subsystems:

(i) Antenna and RF subsystem (ARS)
(ii) Receiving and Archiving Subsystem (RAS), and
(iii) Search and Processing Subsystem (SPS).

ARS performs the following:
i) tracking the RazakSAT^®
(ii) receiving RazakSAT^® X-band downlink signals, and
(iii) demodulation and bit-synchronization of RazakSAT^® signals.

Figure 1

Figure 1 shows the system hardware configuration for receiving RazakSAT^® data. The X-band signal from RazakSAT^® shall be tracked and received by the Hexapod antenna. The signal will then be amplified and down-convert to Intermediate Frequency (IF) before ingested to High rate Data Receiver (HDR) for demodulation of QPSK signal and bit synchronization. Digital output from HDR will be ingested b RAS for recording and real-time display. After preprocessing in RAS, RazakSAT^® data will be transfer to a RAID in SPS for archiving, image product generation and web-based catalogue browsing.
