For a couple of weeks now I am unable to open the https://en.sonik.space/ website

I tried Firefox and Brave, it looks that some css style sheets can’t be loaded.

Here a screenshot

It’s displayed to me correctly using Waterfox.

Hey, Jan!

I’ll take a look what I can do about it. Thanks for sharing an issue.

Same issue here. It seemed like the problem was resolved a few days ago, but it’s here again.

10

works fine here as https://sonik.space/ under Chrome. Then I allow Google translate to go from Russian to English.

11

There is also a translated page https://en.soniks.space/ and there seems to be the issue.

agree, same problem here. Thus my use of the untranslated page, then let google translate do the work. Not perfect, but workable.

13

Based on previous satellites and launches I created a list of gr-satellites Yaml files that are part of this launch.

If there are errors or updates, then please let me know.

superb. yaml master. :dizzy:

Satellites added in DB, in the next hour transmitters will be also added.

I’ve updated the first post with the temporary NORAD IDs.

Satellites will be ready for scheduling in Network near the launch time.

In total 1411 observations have been scheduled for the first ~48h after deployment of the satellites. We have used the TLE sets in the previous post.

The difference in the number of scheduled observations is based to:

  • Frequency of transmission of the satellite
  • Orbit of the satellite/TLE set
  • Request by or communication with the satellite team
  • Spectrum misuse or violation of regulations

I’ll remove some the scheduled observations to share this time with Lobachevsky satellite.

It looks empty from first observation of Sitro-AIS-59 but there is something on the middle left side of the waterfall.

From another satellite?
