Re: [Orekit Users] TLE Propagation Support



Luc,

Sometime we ought to discuss how Orekit processes TLE.

I know about TLE.

Hi Craig,

I'm incorporating the Orekit library into a system that supports a 
student-built microsatellite. The system needs to propagate data from 
a TLE (supplied externally and assumed to be reliable) forward to 
whatever the time is when the spacecraft is in communication with the 
ground station. Which release of the Orekit is better to use? The 
5.0.x published release or a 6.0.x "snapshot" release? I noticed a 
reorganization of the classes related to TLEs between the two versions.
I would suggest to use a snapshot of the upcoming 6.0 version. It is 
not officially published yet, but is probably close. In this version, 
the TLE has been refactored to be compliant with the other 
propagators, which means it can be used together with events 
detectors, including ground station visibility events which may be 
useful to your students.
best regards,
Luc


Thanks,

Craig
