Abstract:
Space-based automatic identification system (AIS) payload has been designed conceptually to provide a platform for AIS signal collection, down conversion, and demodulation of the AIS burst signals operating at VHF band. AIS receiver uses a reconfigurable Software Defined Radio (SDR) technology, which has digital filtering and cross-correlation functions within field programmable gate array (FPGA) device and demodulation of Gaussian minimum-shift keying (GMSK) waveform by a general purpose processor. AIS receiver is able to operate in either or both on-board processing (OBP) mode and on-ground-processing (OGP) mode depending on the availability of communications links, on-board resources and the user preference. In this paper, the link budget analysis and detection probability have carried out as a basic performance analysis of AIS payload for KOMPSAT-6.
