GNSS signal emulation Sample Clauses

GNSS signal emulation. Process through the generation of GNSS signal in the simulator is processed in several steps (and is shown on the picture below): Operator in the simulation program sets the course route (manually or pre-prepared set of positional data, such as NMEA data) and all parameters of the generated signal (e.g. number of available satellites, their output level, a constellation of satellites, signal reflections, near ground relief, etc. - the parameters are defined below), depending on the kind of test. Proprietary data is sent to the GNSS signal generator which generates a defined signal and this is broadcasted into the environment via antenna. Test equipment with the application is located within range of the generated signal and the personal device / application is tested. Data recorded during the tests will be analyzed later on (e.g. comparing the log of the NMEA in Simulator and NMEA log recorded in the test equipment).
