Real Time Kinematic (RTK) SurveyPost Processed Kinematic (PPK) SurveyRTK is a GPS correction technology that provides live corrections to the collected data onsite. PPK is a GPS correction technology that collects the whole location data for the survey first and provides corrections offsite. RTK does not require post-processing of the collected data; hence there is no need for post-processing software packages.The PPK survey requires post-processing of the collected data, demanding specialized software and office work.The base station and the rover receiver (drones) must have a constant and consistent connection to perform the RTK correction. The loss of signal between the base and rover results in data loss.PPK does not demand strong signal strength or GPS communication between the rover (drone) and the base station. RTK works best in flat terrain, with no obstructions like trees, mountains, etc., that would break the communication between the drone and the required base station.PPK drones are best for longer flights and are suitable for Beyond Visual Line of Sight (BVLOS) activities, unlike RTK.RTK works for baselines up to 80 km.PPK survey works for longer baselines up to 100 km.RTK is less flexible due to its baseline restrictions and requirement for continuous signal.PPK is highly flexible as there is more freedom on how and where the rover is deployed.
RTK and PPK surveys take GPS survey, especially drone surveying, to the next level.
Tacheometric Surveying: An Overview
Tacheometric surveying is a popular method of surveying that is used in many areas, such as civil engineering, construction, mapping, and land surveying. It is used for calculating elevations and setting out boundaries and other objects.
RTK vs. PPK: A Comprehensive Comparison
RTK (Real-Time Kinematic) and PPK (Post-Processed Kinematic) are two important technologies utilized in GPS surveying. Both of these technologies provide real-time or post-processed corrections when the data is collected, which is often used as an add-on to a survey drone. The main difference between the two is the processing workflow.
The Choice Between RTK and PPK: What to Consider
When deciding between RTK and PPK, there are several factors to consider, such as the time and cost of the project, the type of area being surveyed, and the feasibility of the project. RTK may require more time to complete the survey, but PPK may require more time for post-processing the data. Ultimately, the choice between the two technologies should be based on the specific needs of the project.
