[Orekit Developers] Azimuth and computeLimitVisibilityPoint



Hi,

I'm abit confused by the computeLimitVisibilityPoint results. For a topocentric frame I would assume azimuth 0.0 is north direction? This code snippet (python) translate it to a longitude offset to the station?

Any comments welcome.

ITRF2005 = FramesFactory.getITRF2005()

earth = OneAxisEllipsoid(Constants.WGS84_EARTH_EQUATORIAL_RADIUS,
    ...:                                  Constants.WGS84_EARTH_FLATTENING,
    ...:                                  ITRF2005)
    ...: staFrame = TopocentricFrame(earth, GeodeticPoint(0.0,0.0,0.0), 'test')

print staFrame.computeLimitVisibilityPoint(Constants.WGS84_EARTH_EQUATORIAL_RADIUS+600000, 0.0,5.0)
{lat: 0 deg, lon: 148,4942265118 deg, alt: 599�999,9999999991}

staFrame.getNorth()
Out[65]: <Vector3D: {-0; -0; 1}>
