gnsstk::GPSEllipsoid Class Reference

Detailed Description

This class represents the ellipsoidal model defined in ICD-GPS-200. This ellipsoid model was based on the WGS 84 model, which has changed since the ICD-GPS-200 was written. To save the cost of having to update all of the fielded receivers, these constants were kept for GPS purposes.

Only some of the WGS 84 ellipsoid model parameters are defined as part of the 200. These parameters are explicitly defined here. Other parameters are inherited from the WGS84Ellipsoid definition.
