P-Code

GPS precision code

GPS Precision Code (P-Code) is a type of signal transmitted by GPS satellites that provides precise location and timing information. It is a higher-precision signal compared to the Coarse/Acquisition (<a href="https://aerobook.com/acronym/c/a/coarse-acquisition">C/A</a>) code, which is available for civilian use. The P-Code is encrypted and reserved for military and other authorized users, providing a more accurate and secure positioning capability.
