 COE has an awkward was of representing phase. Dig it out from the different places it is stored based on the orbit params.

Detailed Description

A "struct-like" class that holds all the orbital elements determined by RVtoCOE and used by COEtoRV. There are some specific cases that need to be considered:

General orbit (e != 0, i != 0): orientation given by raan, argp Equitorial, e !=0 i = 0 longper (longitide of perigee) [OrbitU uses this as omega_lc] Inclined, circular

Member Function Documentation

◆ GetPhase()

double OrbitUtils.OrbitElements.GetPhase ( )

COE has an awkward was of representing phase. Dig it out from the different places it is stored based on the orbit params.

Parameters
phaseRadians
Returns

◆ SetPhase()

void OrbitUtils.OrbitElements.SetPhase ( double  phaseRadians)

Set the phase of the orbit. Requires some care since depending on the orbit type different fields in the OE class are used. This derives from the algorithms taken from Vallado.

Parameters
phaseRadians
