Re: [Orekit Users] Newbye question on how to get satellite location given a TLE

A really good tutorial for doing this sort of analysis can be found on the main website at:

https://www.orekit.org/forge/projects/orekit/wiki/PropagationTutorial#Events-management

In that example they are using a two-body propagator. Once you have that example working it is pretty easy to just swap out your TLE propagator for the two-body one.

Hi and compliments for your super project!

I'm a newbye and moreover I know nothing about background concept of this project.

I'm simply developing a software in which I have to find azimuth and elevation of a Satellite at a given time from a given Ground Station. Moreover I want to find Satellite lat and long.

What I have tryed to do is: after setting OREKIT_DATA_PATH, create a TLE object

TLE tle = new TLE(
"1 07530U 74089B 14068.85842801 -.00000028 00000-0 96998-4 0 9129",

"2 07530 101.4628 53.9967 0012290 127.9050 292.4577 12.53603117799073");

TLEPropagator propagator = TLEPropagator.selectExtrapolator(tle);

But I have not found a way to create a ground station. Moreover I can get only PVCoordinates from propagator and I don't know how to get relative angular coordinates to plot satellite position projected on a world map.

How can I get information requested?

Thank you and sorry if my question is silly
