GNSS Simplified for Beginners

[@keyable]

Could you pls also explain whats PDOP? I see this turn everywhere in GPS systems :D

Basically just another data point to tell us if we can trust the position. Closer to 1 is better. If it creeps up toward 3 you might do something like shoot that point multiple times to make sure you are coming up with the same answer.

What @joedouglas6923 said is true, if you're looking for a strict definition PDOP = Position Dilution of Precision. Often you will see HDOP and VDOP along with PDOP, those are Horizontal and Vertical Dilution of Precision respectively and together will determine your PDOP value. Ideal conditions would give you a confidence value < 1, but 1 - 2 will still give a high enough confidence for almost any application where you'd be using the GNSS receivers featured here.
