Description

I'm using Laika to obtain satellite positions in the sky at different times, but I was comparing data from Laika with real measurements and for one of the tests, G28 is offline (sensor doesn't show it, and almanac I use with another similar tool to Laika, also don't report it), but Laika does report it. Is there a way to get Laika to report whether the satellite is online or not? I dug through the code a bit and I can look at the healthy attribute from the PolyEphemeris, but that one still seems to be set to True regardless. Not sure if it's a bug or not, just hoping to get some help so I can use Laika to estimate satellite positions.

Thanks in advance!

Research direction

Start by tracing how Laika constructs PolyEphemeris and sets its healthy attribute for G28. Compare that state with the reported sensor and almanac behavior, then determine whether the existing interface can represent satellite availability; done means the behavior is corrected or the limitation is documented.
