Hey Jasem!

I was wondering if I could expand the kstars satellite functionality. I have two features in mind:

  • I want to be able to see the TLEs of a given satellite without having to go to the .dat file. It would be nice if I could just right click on it and get it from an info box or something like that
  • I would like to implement the features I just included in INDI but for Ekos, so I don't have to copy-paste TLEs all the time, they are already in Kstars after all I just have to adapt the interface

Any thoughts? If you think it's interesting, where in the Kstars codebase should I start?

I checked that box and it seemed to have no effect (I just checked the logs). But now that I know what to expect, I will do some more digging to see if the problem is caused by the changes I just made, thanks. In the meantime I will wait for the 3.5.0 update. Looking forward!

Hey guys!

I just wanted to give you an update: the software works perfectly! We are just currently struggling with the mount clock, since for accurate TLE-based tracking one needs a time accuracy of within 0.2s of UTC :silly:

Attached you find a video of our last acquisition, it's an upper stage:

https://indilib.org/media/kunena/attachments/5902/indi_record_2020-09-0920-47-50_short_edit_edit.mkv


A (kinda) related question I have, I was trying to add the functionality necessary to synchronize from Ekos with a button that sends the current system time (which should be close to UTC thanks to NTP on a properly configured computer) because the current "update time" of Ekos creates a pop-up which in the best case introduces a 1 second delay (while the user clicks away the pop-up. Is there a more elegant way to keep the mount time updated from Ekos?

Also another problem I had, I built the library from source after changing the 10micron driver (to include the changes I just mentioned) but Ekos did not show any changes, even after I uninstalled indi completely and reinstalled it with
sudo make install
. Any idea what that could be?

Keep up the awesome work! Thanks in advance!

Hi,

yes, yes I know, I said I would create a pull request soon and it only happened now :) anyhow, the pull request has been created and we have been able to snap some goodies at uni. The camera is not the best for this purposes, but one can roughly recognize the H-shape of the ISS...

Cheers!

Hi,

thank you all for your replies! I will most definitely post my updates here.

@knro I will definitely take a look at those issues, I think we also had issues with the tracking after the meridian flip but it might have to do with our mount model not being that great, we have to do some adjustments still

@mworion WOW!!! Last time I took a look at the mount wizard was a looooong time ago, it has grown so much since then! You've done an amazing job there. I will most definitely take a look at it and maybe even contribute, although since I already did quite a bit of development in INDI proper I will probably keep working on the INDI-Ekos combination :)

Talk soon

Hi there!

So as part of a student project at the Technical University of Munich I made some changes to the LX200 10Micron driver in order to add the satellite tracking capability included in later versions. I still need to do some debugging and polishing and after that I would like to create a pull request and merge my changes upstream, I'm guessing some time around end of January. A short introduction to the project: we want to use the 10Micron mount together with a Celestron to track satellites and derive light curves from them, eventually we would like to automatically get precession and nutation information based on optical observations of uncontrolled satellites like ENVISAT.

My main concerns are as follows:

  • Since satellite tracking appears on a later version of the mount firmware (from 2.8.8) I do not want to break anything by building something version-specific. Are there version checks in INDI that I can copy? I could not find any but I did not look around that much :dry:
  • I made a lot of commits often with silly bugfixes or small increments. Should I clean up the history before creating the request
  • I worry that the status of the mount has to be broadcast somewhere else in INDI, although I could not find any sort of satellite tracking marks on inditelescope.h is there anything I should consider given that the mount is following an irregular trajectory?

I close with a question, is there any other driver that has a satellite tracking implementation? I looked around a bit but also couldn't find any :)

Thanks a lot in advance! I like this library SO. MUCH.

Best,
Pedro
