Public Member Functions

 NEDUtil (const double refGdLatRad, const double refLonRad)
 Given a location as a (geodetic) latitude and longitude the constructor creates the appropriate rotation matrix from XYZ to NED and retains it for later use.
gpstk::Vector< double > convertToNED (const gpstk::Vector< double > &inV) const
 Convert from a vector in ECEF XYZ to ECEF NED using the current rotation matrix.
gpstk::Triple convertToNED (const gpstk::Triple &inVec) const
gpstk::Xvt convertToNED (const gpstk::Xvt &in) const
void updatePosition (const double refLatRad, const double refLonRad)

Parameters:
refGeodeticLatRad geodetic latitude of point of interest (radians)
refLonRad longitude of point of interest (radians).
