Rtk drone definition1/23/2024 ![]() The first of these objects is able to calculate the location through the signal received from the GNSS satellites. Since a single base station can be used simultaneously by all receivers within the corresponding range, fixed stations are ideal for test fields or test tracks, confined spaces in an area of up to 10 kilometers to ensure maximum safety.Īn RTK system consists of a base station and a mobile device. To do this, it will be necessary to calculate and transmit the differential correction data via a radio system with which the roving GPS system corrects its position. RTK can be used to improve the positional accuracy of VBOX GPS systems. Errors found in the GNSS results are determined and corrected using RTK technology. Real Time Kinematic is, as mentioned above, a surveying technology that measures relative positions using two Global Navigation Satellite System (GNSS) antennas in real time to obtain greater accuracy. ![]() The result is much more accurate than traditional GNSS solutions, which are based on the position of different devices, such as smartphones and handheld devices, among others. It uses the signal received from satellite-based positioning systems such as GPS, Galileo, BeiDou and GLONASS. Real Time Kinematic, also known by its acronym RTK, is a technique that offers high precision in determining the position of the receiver. Over time, these devices have been offering new features, such as RTK, known as Real Time Kinematic. A UAV can be defined as an unmanned aerial vehicle that is capable of autonomously maintaining a controlled and sustained level of flight. Survey frequency: If your surveying project requires regular site monitoring and the most up-to-date survey data, then PPK drone surveying may be a good fit for your company.The drone industry has experienced tremendous growth in recent years. Project budget: PPK drone surveying can be a cost-effective solution for surveying your worksite, as it reduces the time and labor when compared with traditional survey methods. If your worksite is such where a base station and/or network of AeroPoints can be used, then PPK drone surveying may be a good option for delivering accurate results. Surveying environment: Using PPK does require access to a base station or network of smart ground control, like AeroPoints, for post-processing your survey data. If your projects require high levels of accuracy, then a PPK workflow with a platform like Propeller can be a good fit. ![]() Here are some factors to consider when deciding if PPK drone surveying is the right solution for you:Īccuracy requirements: PPK drone surveying can provide centimeter-level accuracy in surveying data. Is PPK drone surveying right for my company? While “real-time” technologies are appropriate in some situations, post-processing flight data using a PPK workflow brings an additional layer of reliability to your surveys. Then the initial, less-than-accurate onboard GPS data is corrected, giving precise geotags for the imagery While this is happening, a base (be it a base station, an AeroPoint, or coordinate reference system network) is also recording positional information, but with much more accurate triangulation.Īfter the flight is over, those two sets of GPS data are matched up using the photo timestamp. With PPK, the drone will geotag X,Y,Z coordinates to each image based on that on-board GPS unit. PPK stands for “post-processing kinematic.” The difference with PPK workflows is how we process base station data for correction and accuracy. PPK isn’t hardware, but rather a different processing workflow using an RTK drone. This is where things get tricky because we’re not strictly comparing apples to apples. ![]() Now, you might be wondering where does PPK come in.
