Introducing the NEW Trinity F9 VTOL with PPK for mapping

QUANTUM-SYSTEMS ABOUT PPK & RTK

PPK and RTK (post-processing kinematics and real-time kinematics) are the algorithms that allow the user to cancel most of GNSS errors via processing data from two receivers that are close enough to each other. 

They share the same common errors for most error sources such as ionospheric and tropospheric influence on the signal transmission, satellites ephemeris and clock errors. 

As is clear from the names, RTK is performed in real time, PPK – in post-processing.

When properly applied, these algorithms reduce positioning errors from several meters (typical for standalone GNSS receivers) down to several centimeters.

The Quantum Systems current approach of choice is PPK:

• The base station on the ground must be deployed and georeferenced (if high absolute precision is required) for RTK, PPK can make use of already pre-deployed continuously operating reference stations (a dense enough network of these exists e.g. in USA, Europe, Australia, Japan). If you operate with your own reference station, the data can be logged and used in post processing just as well.
• The real-time corrections transfer from the ground station adds additional complexity to the system for RTK, and thus reduces reliability.
• The so called forward-backward processing is possible in post-processing, which raises the precise positioning reliability.
• With our QBase mission planning software we have created a simple and straightforward process of applying PPK to your mission data. The UI enables you to choose different sources of PPK reference data to optimize your results.
