Identification NORAD ID 58266

ali_mohamed · December 17, 2023, 6:19am

I had registered our satellite on satnogs with a temporary NORAD ID (99027). And since then, the NORAD ID of our satellite has been changed to 58266.
I would like to know the process for assigning the NORAD ID?

Hi @ali_mohamed and welcome in the community!

Currently our main way to identify NORAD objects happens through checking observations, from Network or from strf tools, against the published TLE by using the Doppler effect of the received signal.

You can check this process for DJIBUTI-1A and the other satellites on this launch in “SpaceX F9 Transporter-9 - Vandenberg - 2023-11-11 18:47 UTC”

Especially in this post, you will find the status report where includes DJIBUTI-1A identification and the evidence that shows why object 58266 is best fit for it.

Here are the tools that we usually use:

Hi Fredy,
I wanted to install the strf software, but I have some issues as you can see in the below image. Could you please help!

# Setting up STRF Data Capture & Processing

Author: Mark Jessop (VK5QI) <vk5qi@rfhead.net>

This guide provides information on how to capture FFT data using the [strf](https://github.com/cbassa/strf) toolset, process it to look for satellite signals, and finally compare their doppler shift against TLEs from the SpaceTrack database. This can help with resolving the 'TLE lottery' after new launches, or cataloguing transmissions from spacecraft already in orbit.

It should be noted that the analysis described in this document is but a small subset of what the strf tools are capable of! Scott Tilley has a post describing some of the history behind strf and giving a crash course on the relationship between orbital dynamics and the doppler effect here: https://skyriddles.wordpress.com/2019/01/04/basic-orbital-dynamics/

The target platform is Debian-based distributions (e.g. Debian, Raspbian, Ubuntu), but should be applicable to other Linux-based platforms. The data processing software (rfplot and rffit) is also known to work fine under OSX (using Macports to supply the required dependencies).

Hello,
I tried to download the strf software but am having some problems. Also, I see that it requires hardware like an RTL-SDR receiver to use the strf software (I don’t have this receiver). I wanted to use the Doppler effect and I’m wondering what software I can use to interpose a waterfull signal and that of the TLE in order to identify the ID of our DJIBOUTI-1A satellite.

Thanks for your help!

Have a look at Alfredos-Panagiotis Damkalis / Ikhnos · GitLab this can be used in combination with SatNOGS observations.

This will give you an output similar to this image:

Following the steps to install Strf, I encountered a problem at this step (see below image), could you help me?
