NAYIF-1 re-entry

Satellites & Observations

In this thread we are going to track NAYIF-1 (EO-88, FUNCUBE-5) re-entry.

Here is one TLE based on 1682 - N5ZKK-VHF-Helical observations. Not very accurate but better than the current one.

NAYIF-1
1 42017U          23199.20000000  .00000000  00000-0  00000-0 0    03
2 42017  97.1939 272.0530 0014074 339.5038  39.3040 16.29558364    08

To station owners, as the TLE are expected to change a lot the next hours/days, please don’t schedule too far in the future, I would suggest 3-6h is good, except if you remove and re-schedule your observations when we have new TLE.

I’m planning on doing a demod on a bunch of observations that either has no frames or missing due to doppler. Sending them in via SiDS and tagging with the appropriate station name and location.
At the end of this we can do a DB export and sent it over to the EO-88 team. It would be cool if it could be added to the warehouse.

The results of the demodulation of the last days. I want to place them in DB as well but have not done so yet.

It has been demodulated with gr_satellites and bracketed --f_offset between 5kHz and 12kHz to catch the packages that was way off because of doppler change.
The kiss files contains data frames and timestamps, the csv is the same format as DB export.

The following is a combined and de-duplicated result for each observation, only in DB export format.
