GNSS Simulation

GPS simulatorer er radiofrekvens genererende instrumenter som er i stand til å overføre de samme data som GPS-satellittene. Verdien til en GPS simulator er dens evne til å endre en rekke parametere rett fra test benken.

Nortelco Electronics tilbyr GPS simulatorer fra Spectracom.

Parameters that can be testet from the test bench:

Data from the satellite: Conditions as seen by the receiver: Position of the receiver:
Date/Time via the clock parameters  Number of satellite signals Start position (latitude, longitude and elevation)
Satellite ID (PRN code) Power level Trajectory (motion path)
Ephemeris and almanac Atmospheric and antenna errors through models  
  Multi-path conditions  

It is the combination of all these parameters that make up a “scenario” for a GPS simulator.
