Table B.18 Position flags 2: bit values
Bit Meaning
0 Differential position
0: Differential position is an autonomous or a WAAS solution.
1: Position is a differential solution.
1 Differential position method
0: Code
1: Phase including RTK, HP or XP OmniSTAR (VBS is not derived from Phase).
2 Differential position method
0: Code (DGPS) or a float position (RTK). Uncorrected position is Autonomous
(if bit 0 = 0).
1: Position is fixed integer phase position (RTK). Uncorrected position is WAAS
(if bit 0 = 0).
3 OmniSTAR solution
0: Not active
1: OmniSTAR differential solution (including HP, XP, and VBS)
4 Position determined with static as a constraint
0: No. 1: Yes.
5 Position is network RTK solution
0: No. 1: Yes.
6 Position is Location RTK
0: No. 1: Yes.
7 Reserved (set to zero)
