PPP (Precise Point Positioning) ja RTK (Real-Time Kinematic)
PPP is a combination of several relatively sophisticated GNSS position refinement
techniques that can be used with near-consumer-grade hardware to yield near-
survey-grade results. PPP uses a single GNSS receiver, unlike standard RTK
methods, which use a temporarily fixed base receiver in the field as well as a
relatively nearby mobile receiver.
RTK – GNSS satelliit saadab signaali nii rover stationile kui ka base stationile.
Rover station aga saab base stationilt correction data. Kokkuvõtvalt on tegemist
keerulise protsessiga, kus RTK (Real-Time Kinematic) on pmst correctioniga gnss
signaal, mida saab kas real-time kasutada või jätta post-proccessinguks.
