GNSS Point Positioning
•Location Data is collected for a point
•Stationary for an extended period of time
•Move to another location, repeat the process
(X,Y,Z)
Accuracy

12. •The remote receiver applies the corrections to the
measured pseudoranges and performs point
positioning with the corrected pseudoranges.
•The use of the corrected pseudoranges improves the
position accuracy with respect to the base station.
