SUMMARY

The ephemeris data of satellites is standardized as Two-Line Element (TLE) files, which are utilized for various satellite constellations, including Starlink. While TLE files are the primary format, CelesTrack offers additional formats such as OMM (Orbit Messaging Message) that can be accessed in XML or JSON. This indicates that while TLE is a common standard, alternative formats exist for specific applications and data needs.

PREREQUISITES
  • Understanding of Two-Line Element (TLE) format
  • Familiarity with satellite ephemeris data
  • Knowledge of CelesTrack and its functionalities
  • Basic concepts of orbital mechanics
NEXT STEPS
  • Research the structure and usage of TLE files in satellite tracking
  • Explore CelesTrack's OMM format and its applications
  • Learn about satellite constellations and their data requirements
  • Investigate tools for visualizing satellite orbits using TLE data
USEFUL FOR

Satellite engineers, astronomers, data scientists, and anyone involved in satellite tracking and orbital analysis will benefit from this discussion.

Hi,

Is ephemeris data of satellites standardized as TLE files or different constellations have different formats?
 
Physics news on Phys.org
As far as I know constellation satellites (such as Starlink) are still included in the usual two-line element set, e.g. https://heavens-above.com/orbit.aspx?satid=62487

By the way, you wrote "ephemeris" but since that is a table of positions over time I assume you mean "elements" as in orbital elements.
 
Follow up:
CelesTrack has a lot of pre-made satellite groups and different formats, with the elements of each group accessible as both TLE and OMM (transferred as XML, JSON or similar).
 
Thanks.
 

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
