Condition GR10/GR25/GM10
L1, AS off Carrier phase smoothed code measurements: C/A-code.
L1, AS on
L2, AS off Carrier phase smoothed code measurements: P2-code and/or L2C code.
L2, AS on Carrier phase smoothed code measurements: Patented P-code aided code and/or L2C code.
Carrier phase and code measurements on L1, L2 and L5 (GPS) are fully independent with AS on or off.
