Abstract
This paper presents a novel space-based automatic identification system (AIS) receiver architecture meant for maritime surveillance. The receiver performance has been simulated in the presence of three AIS Tx signal messages colliding in different combinations of frequency, time and power. Doppler shift due to the LEO satellite moving at a velocity of 7.5 km/s at an altitude of 600–900 km, and the delay in signal transmission was also induced in the AIS Tx signals to fully characterize the AIS receiver. The architecture proposed in this paper is suited for on-board processing on any nanosatellite with enhanced message and ship detection capability. The performance parameters of the proposed AIS receiver in the collision environment have been tabulated in the results’ section.
