Hi
Your GPS antenna does not have a clue where signals are coming from. The only
way things get plotted is based on the almanac data. If it sees sat Id 21, it
looks in
the almanac for id 21. If the almanac says it’s over India, that’s where it
goes on the
resulting plot.
Best guess: you are seeing intermod of some sort that your receiver interprets
as a
signal from a sat that can’t actually be in view.
I don't know that an intermod would do that (PN sequences are different)
- multipath, for sure.
