- 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
- orbital mechanics - How to convert TEME (or ITRF) to horizontal . . .
I have TEME coordinates from sgp4 propagation I can convert those (in python) to ITRF given date and time of observation How to convert coordinates from one of those two frames to horizontal azim
- Eccentricity of TLE orbit from velocity and radius in TEME
The data in the TLE aren't really orbital elements, even though many fields have the same name They are just values generated to reproduce the actual position and velocity within some tolerance when using the SGP algorithm So it's best to assume anything in a TLE is useless outside of the SGP algorithm
- Fixing satellite eclipse equations from textbooks that are seemingly . . .
I have tried implementing equations from two different textbooks in Python to find if a satellite is in eclipse, but both fail a significant percentage of the time when tested against data from ind
- 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
- 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
- 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
- planet - Planetary reference systems and time - Astronomy Stack Exchange
I am researching into how coordinate systems of solar systems objects are created by reading some of the reports written by the Working Group on Cartographic Coordinates and Rotational Elements (e g
