Correct.
And clear line of sight.
If it can’t see >=4 satellites it can’t know where it is. I guess how the individual unit handles the uncertainty is down to whoever wrote the firmware, and its likely that they differ between models. And it’ll be wrong. Maybe a bit, maybe enough to notice.
And some of them insist on assuming you’re on a road on their map when it’s patently obvious you’re not, and then jump. Bottom line is we don’t know what the software does with the data, assuming the data is good.
Anyway, apart from guilding mossie’s todgers, if you have GPS evidence that you were doing, let’s say 32mph, and the copper says you were doing 34, will you get off?
