Abstract:

An effective and innovative Automatic Identification System (AIS) receiver design for maritime surveillance applications is presented in this study. The frequency of the receiving signal, the collision time, and the power level of the signals for VHF channels of AIS 87 B & 88 B have all been changed for the proposed receiver architecture, and simulations have been run to assess how well it performs in these different message collision cases. The Doppler shift resulting from the LEO satellite’s orbital velocity at an altitude of 600–900 km, the signal transmission delay resulting from propagation time, as well as the signal power level based on the distance that the AIS transmission signals must travel have all been introduced to characterize the AIS receiver. Particularly in locations with a large density of ships, the suggested design in the present study is appropriate for creating an AIS receiver employing software-defined radio and on-board message processing capabilities that may be started on any Nanosatellite with better AIS signal decoding. Based on the simulation results, the sections below tabulate the efficiency of the suggested AIS receiver in the collision scenario when the AIS Transmit signals from two and three collided in various combinations due to varied signal characteristics.
