Constructor Detail

TopocentricPV

public TopocentricPV(double elevation,
                     double azimuth,
                     double range,
                     double elevationRate,
                     double azimuthRate,
                     double rangeRate)

Build topocentric coordinates. To be consistent with the TopocentricFrame, the convention concerning the azimuth is the same ie azimuth angles are counted clockwise from the local North.

Parameters:

elevation - elevation angle in radian, between -PI/2 and PI/2

azimuth - azimuth angle in radian, between 0 and 2PI

range - distance from the origin of the topocentric frame

elevationRate - elevation rate in rad/s

azimuthRate - azimuth rate in rad/s

rangeRate - range rate in m/s

Overrides:

toString in class Object

Returns:

string representation of this position/velocity
