Satellites orbit

Here are the 3D graphs of the Earth's artificial satellites in the TEME and ECEF reference frames.

The Earth is shown as the WGS-72 ellipsoid (equatorial radius = 6378.135 km and flattening = 1 / 298.26, which gives a polar radius of about 6356.75 km).


Here's the orbit in the TEME reference frame obtained from the TLE shown above propagated with the SGP4/SDP4 propagator; please, take a look here for further details.
The reference direction (the mean equinox of date) is represented by the +X axis direction.

The label that appears when you hover the mouse over a point shows: UTC time, radius vector (km), inertial orbital speed (m/s), latitude and longitude (degrees), altitude above the WGS-72 ellipsoid (km).


Here's the same graph as above but in the ECEF reference frame.

The popup label shows: UTC time, radius vector (km), ECEF orbital speed (m/s), latitude and longitude (degrees), altitude above the WGS-72 ellipsoid (km).


The following map shows the satellite ground path.
