TLE and magnetic info from DB

SatNOGS

Hello,

I am just a newcomer here.

I found TLE info here: SatNOGS DB API, but would it be possible to find the historical TLE for specific satellite?

Besides, I would be interested to collect data from satellites with magnetometers. Is it possible to collect magnetometer’s data in the SatNOGS DB for a specific satellite? For example: SNUGLITE (43784)

Finally, I would like to ask you how to decoder the HEX data:

https://network.satnogs.org/observations/11383926/

where one of them is:
data_obs/2025/4/10/9/11383926/data_11383926_2025-04- 10T09-51-19_g0:

Good afternoon,

I hope someone else can answer your TLE question.

Regarding the hex decoding:

48 A3

We are completely depending on the satellite team and if it isn’t shared as in this case we can’t decode the hex data.

If the information is available you can expect a dashboard on the following page.

Good afternoon,

thank you so much for the information, it has been really useful

Unfortunately currently, while we keep them, we don’t offer an API for historical TLE/orbital data. However for some limited request we may be able to extract them. An alternative that you could use is space-track.org.

You can extract satellite frames in hex form from SatNOGS DB, either from the API or for more massive export from the satellite page under the data tab. For decoding them, as @PE0SAT mentioned you need to know how to do it, we have a collection of decoding schemes that, through kaitai.io, create decoders, you can find them in librespacefoundation / SatNOGS / satnogs-decoders · GitLab.
