Detailed Description

Position, velocity and time

Requirements: position is in degrees (though that is only required by setFromPair with isAngle=true). velocity is in degrees/unit of time. However, as used within this package, time is always TAI (MJD, seconds).

void coordConv::PVT::setFromPair ( double const  posPair[2], double  t, double  deltaT, bool  isAngle  )

inline

Set from a pair of positions or angles computed at different times

Parameters

[in]	posPair	pair of positions, where: posPair[0] is computed at time t posPair[1] is computed at time t + deltaT
[in]	t	time at which posPair[0] is computed
[in]	deltaT	time difference between the two positions
[in]	isAngle	if true then posPair values are treated as angles, in degrees, and the resulting velocity is computed using: posPair[1] - posPair[0] wrapped into the range [-180, 180)

Warning

if isAngle true then posPair must be in degrees
