Station Geodetics File

Top  Previous  Next

The Station Geodetics File (groundstations.dat) is a binary file delivered with FreeFlyer and contains an extensive list of ground station locations including those associated with the AFSCN (Air Force Satellite Control Network), the DOD (U.S. Department of Defense), the Deep Space Network (DSN) and NASA ground stations. The file provides ground station information, including station coordinates and masking data. You can import this data directly to a FreeFlyer GroundStation object from the Station Geodetics File.

 

FreeFlyer uses the Earth-Fixed position vector that is provided in the Station Geodetics File to calculate the geodetic latitude, longitude and height of the GroundStation object based on the Earth.Radius and Earth.Flattening properties, which by default are set to model the WGS-84 (World Geodetic System 1984) ellipsoid.  See the Gravity Model Files page and how to configure a CelestialObject for more information about setting properties of the Earth.  FreeFlyer uses the raw azimuth and elevation data (no conversions or rotations are applied) provided in the Station Geodetics File for the GroundStation masks.
