RTK technology, namely real-time dynamic differential technology, is a differential method that uses carrier phase to process the observed quantities between test stations in real time.
PPK technology, namely dynamic post-processing difference technology, is a GNSS positioning technology that uses carrier phase for post-difference.
One is to obtain the solution results in real-time.
One is the calculation result obtained by subsequent software processing.
Because the technologies of the two are different,
In a small operating area,
The operation efficiency of RTK is high,
And can provide high-precision position information in real-time.
In a long-distance and wide-range operation area,
PPK will be the best choice.
