P=Precise. Satellite system used in precision mode. Precision mode is defined as: no
deliberate degradation (such as selective availability) and higher resolution code (P-code)
is used to compute position fix. P is also used for satellite system used in multi-frequency,
SBAS or Precise Point Positioning (PPP) mode;
S=Simulator mode;
