UAV WingtraOne PPK* the world-famous Swiss UAV manufacturer, Wingtra, has set a new level in the large-scale geodetic and cartographic fields of activity. Supported by industry partners, photogrammetry software provider Pix4D and GNSS boards from Septentrio, the WingtraOne PPK is capable of transmitting orthomosaics and 3D models with 1cm precision.
*PPK — Post-Processed Kinematics — “kinematics in post processing.”
Wingtra designs, manufactures and markets high-precision VTOL unmanned aerial vehicles for data collection through aerial photography. Wingtra entered the global market in early 2017 and has since been sold worldwide. The company recently partnered with RDO Integrated Controls (a leading surveying equipment dealer) to raise an additional $5.8M to meet demand in 2018.
“With the latest update, the WingtraOne PPK drone can offer something that has not been seen in drone photogrammetry until now — wide coverage and high resolution of precision accuracy. For example, in one hour of flight, WingtraOne will be able to cover 130 hectares, which is 240 football fields, by presenting maps at the output with GSD* less than 1cm/pixel with absolute precision down to 1cm,” explained Wingtra’s CTO Armin Ambühl.
*In English literature GSD — ground sample distance or “pixel size on the ground”
These results are new to the industry — until now, no existing professional UAV could offer such accuracy. Previously, the world of cartography was dominated by only two types of drones: fixed wings and multi-engine or multi-rotor aircraft. Fixed wing drones can cover large areas but cannot transmit highly accurate data. Multi-rotors can provide precision accuracy, but they can only cover small areas.
“The VTOL (vertical takeoff and landing) fixed wing drone combined the two types of drones, resulting in improved control quality and extended flight times,” added Armin Ambühl.
RTK (real-time kinematics) or PPK (post-processed kinematics). RTK requires a real-time connection to the base station and corrects the GPS signals during the flight, while PPK corrects them after the flight and therefore provides more reliability and consistency. In addition, PPK does not depend on base stations or base station networks, and has high reliability, accuracy, convenience and time saving. To obtain accurate aerial photographs up to 1 cm, special flight preparation and intensive post-processing steps are not required.
PPK (Post-Processed Kinematics) technology allows WingtraOne to reach a new level of accuracy. PPK calculates highly accurate geolocations for each image by combining GNSS data with correction data from the nearest reference receiver.
After aerial data collection, Pix4D post-processing software works as a powerful tool for creating orthophotos and 3D models from geotagged images. Armin Ambühl notes that “after processing the data, the results become visual — orthomosaic and 3D models are impressively detailed and allow for accurate calculations”
The high payload capacity of WingtraOne allows the integration of the highest level payload on board the drone: the Sony RX1RII and the modern Septentrio PPK system. “An RMS error of 1.3cm horizontally and 2.3cm vertically without any ground control points is a significant leap forward in efficient aerial photography, saving time spent in the field,” says Ambühl. “We are thrilled to offer such a high resolution, high accuracy WingtraOne system to the demanding surveying industry.”
The Wingtra team expects the WingtraOne PPK to become the most sought after drone for surveying and mapping applications. Maximilian Boosfeld, Chief Operating Officer of Wingtra, added: “Our unique VTOL technology has already proven itself in the field: cadastral survey of the largest uranium mine in Africa and digital modeling of the Alpine Heights have helped us establish a solid market footing in this area. By combining the capabilities of VTOL and PPK, we have gained an advantage over existing solutions in aerial photography. I believe WingtraOne will completely replace fixed wing drones in large scale mapping missions in the near future as we have just set a new industry standard in drone photogrammetry.”
