2020年1月16日 · Both PPK and RTK technology can correct satellite data down to cm (sub-inch) levels, and both methods depend on an on-board receiver like the (high-end Septentrio WingtraOne PPK) module pictured, but their fundamental differences include reliability and are worth considering.

2023年6月5日 · The main difference between the two solutions is that PPK corrects the data in the cloud after the drone flight has taken place, while RTK provides real-time corrections to the location data in the moment.

2022年12月8日 · Post Processed Kinematic (PPK) is another GPS correction technology, similar to RTK, that works to correct geotagged located data. The main difference is that location data is updated after the drone has captured images, thus being “post-processed.”

2024年11月19日 · Both RTK and PPK offer significant advantages in terms of mapping accuracy, but the choice ultimately depends on your specific project requirements and constraints. RTK is the more convenient option, providing real-time corrections and eliminating the …

2021年3月26日 · Real-Time Kinematic (RTK) The third method that provides real-time corrections to location data while the survey drone is capturing photos is called RTK. This system collects position data from satellites and references a base station with a GNSS receiver on the ground.

2024年11月11日 · The main difference between RTK and PPK lies in the timing of the correction data. RTK applies corrections in real-time as the drone is in flight, making it ideal for projects where immediate data is required.

2023年10月18日 · Unlike consumer-grade GPS units, RTK drones are equipped with high-precision GPS receivers that enable real-time correction of satellite positioning signals. Post-processing kinematic (PPK) software takes a different approach— instead of providing real-time corrections, PPK relies on post-processing the data collected by the drone

2024年10月16日 · Basically, the main difference between RTK and PPK is the time it takes for the position correction to occur. RTK makes the correction during the flight, which saves time in post-processing, and you can see the coordinates and accuracy of …

Post-processing kinematic (PPK) and real-time kinematic (RTK) workflows are only getting more accessible as new drone technology hits the market. But there’s still a lot of confusion about what this technology is, how it works, and what’s best for your surveying needs.

2022年6月7日 · RTK (real-time kinematic) and PPK (post-processed kinematic) are GPS correctional technologies which help to collect highly-accurate data. They use observations from two GNSS receivers - such as the Emlid Reach RS+ or Reach RS2 - to achieve cm-level positional accuracy.
