How close to the engine (and its candles) can gps be done so that there is no interference?

That is, ten cm is it possible? gps rtk accuracy - 2 cm, I don't want to lose it out of stupidity ..

Answer 1

Complex issue. Depends on placement. If possible, at least the antenna should be placed, in principle, away from massive metal objects. The candle is inside a heavy metal object (cylinder block), and its influence factor is unlikely to cause any serious interference. Although from the side of the engine and wires, I think a screen would not hurt (both for the antenna and for the receiver).

Answer 2

The GPS signal is quite immune to interference, unless, of course, you need geodetic accuracy.
But counting interference in the mind is, of course, a thankless task. The module itself is on the screen, and then check in practice, perhaps - take the antenna.
