Missing TLE

See original GitHub issue

I noticed that most of the new satellites never get scheduled and after checking it seems they lack TLE

This is when the TLE last updated. Previously each satellite had own “tle.txt” file. So this parameter was used to keep track of last update time.

Found it. Here is what going on:

r2cloud starts for the first time
load hardcoded list of satellites
load TLE for ~6k but stores only what r2cloud need. This is to avoid disk pollution with decayed TLEs
you configure leosatdata integration and this will provide additional set of satellites
on next startup r2cloud loads both hardcoded and leosatdata satellites
but the local TLE cache file was not updated yet, thus no additional TLE for leosatdata satellites
as a result: error in the log

There are several ways to fix this:

Do not fix this. r2cloud will wait next housekeeping.tle.periodMillis and reload TLE automatically. Currently 2 days
Reload from celestrak if at least one satellite doesn’t have TLE. That was implemented previously. However if leosatdata or configs contain decayed satellite, then r2cloud will load the TLE from celestrak every time.
