Improved Simulator


Java program that simulates a vessel moving on the face of the earth. Assuming you have all the prerequisites installed you can run the program either directly from eclipse or just download the JAR file and go "java -jar name_of_jar_file.jar>"

The program will simulate a boat navigating around subject to current set and drift but does not (currently) add a leeway factor. The current and various starting parameters are set in a configuration file, described below. The emulation is good enough that it can be used to test various types of navigation software like OpenCPN, iNavX. iRegatta and the like.

NMEA0183 sentences are sent out across the network on a pre-configured port number. Right now we send the following sentences:


Tell your navigation software/whatever to connect to port 1234 of your machine. NMEA 0183 sentences are sent out from the simulation on port 1234
