It is not only the number of sats seen at a given moment at a given locaten, it is also, among other requirements, the distribution of the sats in orbit. (GDOP)
Therefore, as an example, DJI's Mobile SDK does not look at the number of satellites. DJI is using it's own GPS health (0-5) as a reference:
Have a look:
Following enum class represents GPS signal levels, which are used to measure the signal quality.
DJIGPSSignalStatus
Level0 The GPS has almost no signal, which is very bad.
Level1 The GPS signal is very weak.
Level2 The GPS signal is weak.
Level3 The GPS signal is good.
Level4 The GPS signal is very good.
Level5 The GPS signal is very strong.
None There is no GPS signal.
DJI translates that into:
Level0: The GPS has almost no signal, which is very bad.
Level1: The GPS signal is very weak.
Level2: The GPS signal is weak. At this level, the aircraft's go home functionality will still work.
Level3: The GPS signal is good. At this level, the aircraft can hover in the air.
Level4: The GPS signal is very good. At this level, the aircraft can record the home point.
Level5: The GPS signal is very strong.
None: There is no GPS signal.
