Member Function Documentation

◆ AddCols()

static string GravityEngine2.SGP4SatData.AddCols ( string tleLine)
static

The Unity console does not have a fixed width font BUT if open log in Notepad then this can be useful.

Parameters
tleLine
Returns

◆ InitFromCOE()

void GravityEngine2.SGP4SatData.InitFromCOE ( Orbital::COE coeKm,
double timeJD )

Initialize an SGP4 prop structure to propagate from a given COE. Need to provide the correct scale factor to convert GE physics units into km.

Note immediatly after evolution to time=0 there WILL be small changes in the orbit parameters that result from the r, v at time=0. This is par for the course with the SGP4 secular variation code.

Parameters
coeKmClassical orbit elements, distance in km
timeJD

Member Data Documentation

◆ string

GravityEngine2.SGP4SatData.string

Returns
