What is the timezone currently set to? I have the raspberry pi set to UTC-7 but my passes predicted via Orbitron do not match with what r2cloud is reporting. 2020-01-16 21_06_58-r2cloud 2020-01-16 21_07_05-Orbitron 3 71

Thanks

r2cloud has min and guaranteed elevation limits while calculating passes. Default values are:

That means any passes without elevation < 20 are not considered. Also observations starts/ends at 8 degrees of elevation.

Regarding your example, what is the timezone for "Time - LOC" ? What is "Elv" (is it max, or initial or)?

ChadOhman commented 4 years ago

LOC is UTC-7 and Elv is max.

Thanks for your insight.

Yes, Looks like orbitron "NOAA 19 2020-01-17 05:32:39" matches r2cloud on 12:27. 5 minute difference might arise from:

  1. stale TLE in r2cloud
  2. min elevation in r2cloud > min elevation in orbitron.
