Public Member Functions

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

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