Model: PPK aeroPOS software SkyLines
Features
Specification
INTRODUCTION
Transforming more tough fieldwork, like GCP (Ground Control Point) measurements, into fast processing is always enjoyable to surveyors. As a specialized GNSS data software kit, SkyLines is engineered to deal with the flight lines and compute precise aerial positional information of drones equipped with an airborne PPK module. Corrected with base observations by post differential algorithm, the high-precision aerial positioning data is just a few mouse clicks away, which makes it more productive in the drone mapping workflow. By using this powerful tool, drone users can obtain highly accurate POS (Positioning & Orientation System) data at centimeter level via post processing and may be independent of ground control points for further adjustment in aerial triangulation.

WHY PPK ?
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. |  |
