GPSReceiver:

Path: SCPro/ProSensors

% GPS receiver model. Models the GPS constellation. 
   The satellite locations are determined using GPSSatellite.
   The model can output a set of default data.

   Failure mode is zero output. The regular output is a structure:
     .rGPS        (3,n)   Position of GPS satellites in view
     .vGPS        (3,n)   Velocity of satellites
     .range       (1,n)   Range to the satellites (km)
     .rangeRate   (1,n)   Range rate (km/s)
     .iD          (1,n)   ID of satellites in view
     .nSatellites (1,1)   Number of satellites in view
