Why do ~GEO sats seem to cluster around the top portion and bottom portion of the belt, 180 degrees apart?
I made a 3D tle model from https://www.space-track.org/ API. I drew a dashed blue line to show the really "geo" orbits that hardly move with time (ECEF). Then there are a bunch of sats that ...

What would the TLE data (Mean Motion, Eccentricity, Inclination, RAAN, Argument of Pericenter) of GEO and PO be like?
I am currently making a satellite tracker app for android. I want to test my orbit propagation algorithm and I want to make some made-up basic orbits, so I need to know how their TLE would be. I want ...

What size are the typical keep-inside boxes of geostationary telco satellites?
Geo sats need station-keeping and the size of their keep-inside box is a design parameter. A smaller box implies more manoeuvres to stay inside the box. All depending on the various orbit ...

How to attain an equatorial orbital inclination from a non-equatorial launch site?
The orbital inclination of a satellite is limited to inclinations roughly equal or greater than the latitude of the launch site, unless additional energy is expended for an orbital plane change.
In ...
