Design and Implementation of Signal Generator for AIS Ground Testing System
2019
The AIS monitors and demodulates ship signals within the visible range and packs its demodulated information to the ground stations so as to provide a wide range of high-efficiency status data for both marine management and ship operations. The AIS subsystem receiver mainly brings about the real-time capture and data demodulation of the ship-borne AIS signal. In order to complete the comprehensive test of AIS subsystem receiver, the signal source of AIS ground test system is established. The primary mission of signal generator of the system is to generate simulated data in real time, according to the communication protocol stipulated in ITU-R Rev. 1371-5 of the ITU Radiocommunication Sector through simulation and maintenance of LEO satellites, ship status, etc. The communication frame simulates the generation of AIS signals so that the functionality and performance of AIS satellite receiver can be evaluated.
