Abstract
The paper presents a real-time generator of AIS/ARPA/GPS position data in the standardized NMEA 0183 text format. Position data are produced by a set of various types of ships simulated on the Polish part of the Baltic Sea and are generated on defined IP/UDP addresses and RS-232 ports. In the simulation an extensive set of input parameters is taken into account including the number of particular types of ships, their dimensions, speed as well as parameters of AIS equipments, ARPA radars and GPS receivers. The paper describes the architecture and implementation of the generator. Additionally, it demonstrates the application of the developed generator to test the software developed for the Polish Border Guard.
