AIS Radar Application

What is AIS?

All shipping over a certain tonnage is required by maritime law to broadcast, on a fixed VHF frequency, their location, unique ID (MMSI), name and certain other data. Leisure marine craft may optionally broadcast thieir position and a subset of the "big ship" data.  Fixed safety installations such as lighthouses and marker buoys may also transmit their locations to aid navigation. The other notable class of AIS transmitters are emergency (SAR) beacons.  Typical range of ship transmitters is 30-50miles. If you have the appropriate receiver for this frequency, you can track and plot with a high degree of accuracy, the larger marine traffic around you, as well as many navigation beacons.. This application creates a circular plot on a computer screen with the received traffic data identified on it. Analysis of repeated data allows targets to be plotted to show their track (speed and direction) as well as current position.

You Need:            Nasa Marine AIS engine (see Nasamarine.com)

            PC/laptop with serial port or serial-to-USB adaptor
