orbit - Can someone explain to me the TEME reference frame in defining . . . TEME of Epoch—In this approach, the epoch of the TEME frame is held constant Subsequent rotation matrices must therefore account for the change in precession and nutation from the epoch of the TEME frame to the epoch of the transformation
From TEME to RA DEC - Astronomy Stack Exchange The algorithm computes the positions (X, Y, Z) in the True Equator Mean Equinox coordinate frame (TEME) From that, I would like to find the corresponding RA DEC coordinates at the given epoch I thought this was just a change of frame from Cartesian to spherical coordinates, with RA = arctan (Y X) and DEC = arcsin (Z R)
Eccentricity of TLE orbit from velocity and radius in TEME I was reading this question: Calculation of Eccentricity of orbit from velocity and radius and tried to use the proposed equation to reconstruct the ecco field of TLE by it's R,V vectors The formu
Conversion between Astronomical Frames, ex. IRCF, FK5, FK4, etc… I'm a little bit confused about reference frames, and I was wondering if someone could help clarify a few things? So let's say I have equatorial coordinates that refer to the mean equator and equi
How can I calculate the right ascension of an observer on Earths . . . I know that calculating the geocentric position of the respective Topos object at a specific time results in a Geocentric object that has an attribute radec; however I am not confident that this delivers the right ascension in the TEME (Earth centered inertial frame
