Orbicentral

Orbicentral is an easy-to-use website to obtain GP (General Perturbation) element sets, also known as TLE, 3LE, OMM or orbital data, from NORAD/Space-Track. It is primarily designed to be used with SatDump and for private use only. Other users should go to Celestrak or Space-Track directly.

Orbicentral doesn't require user registration and the API is easy to use and compatible with the one used by Celestrak.

Currently Orbicentral does not support supplemental GP data (SupGP), special data, or historical GPs, although this is planned.

New: Download the official Orbicentral app for Android (APK)
Source code available on Codeberg.

Search GP groups by NORAD Catalog Number

If you need to find which groups contain a specific satellite, identified by its NORAD Catalog Number, you can use the form below.

API

You can send requests to http://www.orbicentral.net/gp.php to obtain the GPs you need.
Please be mindful of our very few and simple rules when downloading data from Orbicentral.

Parameters

All of the queries take the form of https://www.orbicentral.net/?{QUERY}=value[&FORMAT=value].
Please note that {QUERY} must be uppercase.

CATNR: retrieve GP data by NORAD catalog number
INTDES: retrieve GP data by international designator
NAME: retrieve GP data by object name, as given by NORAD (use URL encoding)
GROUP: retrieve GP data of all the objects in a group, see the table under the Groups section for a group list
FORMAT: optionally specify combined with the other queries above to obtain data in a preferred format:

csv: comma-separated value OMM file (default if no format is supplied, or if the format supplied is invalid)
xml: CCSDS 502.0 OMM XML file
json: JSON OMM file
json-pretty: JSON OMM file, pretty printed (formatted)
kvn: Key-Value Notation OMM file
2le: Two-Line Element. For objects with CATNR greater than 69999, beware that Alpha-5 CATNRs are used.
3le: Three-Line Element. For objects with CATNR greater than 69999, beware that Alpha-5 CATNRs are used.
tle: Same as 3le above.
