Abstract [en]

This project mainly consisted of implementing the software for a system simulator, which will be used during development and testing of a navigation and communication equipment. The system is called GP&C (Global Positioning and Communication system) and is primary intended for aviation and maritime applications.

The GP&C equipment does essentially consist of a GPS-receiver and a radio transceiver, connected to a communication processor. A large number of such units, called GP&C transponders, send information about their positions on a shared radio channel in different time slots. By listening to the radio traffic, every transponder has access to position data of all other units.

Running the system simulator, an operator defines a number of simulated transponders and specifies which types of messages these shall send. Furthermore the operator declares data for each message and in which time slots the messages will be sent. Given data will be processed and sent out through a connected radio transceiver. The simulator, like the transponders, obtain a precise time base from GPS-satellites via connected GPS-receiver, making system synchronization possible. The system simulator records the radio signals broadcasted by real transponders, hence one can analyse how they react on the simulated transponders radio broadcasts.
