PPK, short for Post Processed Kinematic, is a GNSS positioning technique that obtains 

post differential corrections with carrier phases. Compared with RTK technology, PPK 

enjoys datalink transmission free, as base station and rover device would just individually 

store their data records that are post processed after the survey has been completed. 

This is utilized to improve the aerial positioning accuracy of drones which might find it 

difficult to obtain RTK fixed solutions during missions especially in case of poor satellite 

signals or weak datalink transmission.

• Applicable for DJI Phantom4RTK or any other drone equipped with GNSS module 

• Intuitive interfaces and optimized algorithm ready for fast processing 

• Full constellation options with more operational flexibilities 

• Observation file timeline display available

• Suited to post process both static and kinematic GPS data

• Centimeter grade outputs, more reliable than simply aerial RTK positioning results

• Supports WGS84 and local coordinate systems both 

• Simplifies drone survey fieldwork by effectively eliminating GCP measurements 

• Dongle-free version available for trial use upon request
