AIS (Automatic Identification system) is an automatic and autonomous vessel tracking and identifying system that uses maritime VHF frequency band. AIS was developed for collision avoidance mainly. AIS transmit GMSK modulated signal using self organized form of TDMA. Its communication range is limited to 40 NM. SB-AIS can be proposed to overcome this limitation and create global surveillance. AIS signal strength can be received at LEO satellite up to 1000 km. satellite is not continuously visible to ships. So that is required to do visibility analysis. MATLAB simulation is done to find all parameters like path loss, received signal power, Doppler frequency, within visible duration only.
