There are some regions of the world that have better AIS reception than others. Variation results from the presence or absence of a satellite flying overhead at any given time, proximity of terrestrial receivers in the area, vessel densities (which can cause signal interference) and whether or not vessels are transmitting. Overall, reception continues to improve with the continual deployment of more satellites and with more recent years having substantially better coverage than 2012 due to satellite increases and changes in AIS usage mandates.
