    Oblique 3D Mapping Payload

    “We wanted to make the WingtraOne drone even more versatile for our customers. So next to our flagship 42MP Sony RX1, we’re including new, high-end mapping payloads,” said Maximilian Boosfeld, co-founder and CEO of Wingtra. “I’m especially excited to announce our oblique solution, which offers outstanding 3D mapping results. It’s the perfect choice for capturing infrastructure — from a single industrial plant to entire cities.”

    WingtraOne’s GEN II oblique mapping solution is backed by signed partnership agreements with Bentley Systems and Esri. To demonstrate the power of GEN II carrying its Oblique Sony A6100 payload, the Wingtra team mapped the city of Zurich, Switzerland, in six flight hours, producing a 3D model processed with both Bentley ContextCapture and Esri’s Site Scan for ArcGIS. Bentley and Esri’s software are both recommended for processing Wingtra oblique datasets.

    “Bentley Systems is delighted to partner with Wingtra to transform high-resolution oblique imagery from WingtraOne drones into 3D reality meshes — an ideal starting point for infrastructure digital twins,” said Phil Christensen, VP, Industry Solutions, iTwin Context, Bentley Systems. “This enables our common users to perform analytics on the resulting models as well as leverage Bentley’s iTwin platform to share performant, city-scale digital twins.”

    “Our partnership with Wingtra unlocks new capabilities for Site Scan for ArcGIS users by allowing them to create wide-scale and accurate 3D meshes leveraging the oblique payload on the WingtraOne Gen II,” said Richard Cooke, director of Global Business Development at Esri. “These high-resolution images processed through Site Scan produce an enriched 3D GIS for our users who require modelling of open-pit mines, accurate construction updates, creation of digital twins for cities, and more.”

    Integrated PPK and Self-Diagnosis

    WingtraOne GEN II features post-processed kinematic (PPK) ability integrated on every drone, including multispectral Altum and RedEdge payloads, as well as advanced fail-safe and self-diagnosis algorithms and services for dependable operations.

    “We have studied over 100,000 flights and all incoming customer reports to understand what the limits might be so we can push them further,” said Julian Surber, Wingtra product manager. “As a result, we’ve designed many reliability tools for GEN II to guarantee uninterrupted operations.”

    Wingtra’s engineering team has redesigned the electronics of the GEN II from its predecessor WingtraOne for increased reliability, including a more powerful onboard computer, optimized PCB designs, and a new navigation and heading unit developed inhouse.

    The GEN II runs through health-monitoring algorithms for motors, servos, batteries, camera, PPK and onboard sensors, health self checks that minimize the potential of flight  with unsafe equipment.

    Precision Agriculture Boost

    Wingtra’s top-of-the-line multispectral payloads Micasense Altum and RedEdge will now be paired with high-accuracy PPK, which improves the quality of multispectral insights for uses such as irrigation management and prescription maps for pesticides.

    Avalanches can be a danger for skiers as well as for the resort towns that welcome them. For protection, towns erect steel fences to act as barriers along the ski slopes. But before these snow barriers can be built, steep rock faces and cliffs need to be surveyed.

    Darnuzer Ingenieure AG, a Swiss-based surveying and mapping company, uses a drone with a built-in high-performance GPS receiver to survey these harsh areas in hours.

    “Drones have made mapping workflows faster, safer and more efficient,” said Septentrio’s senior market access manager Gustavo Lopez. “GNSS technology has led to the evolution of post-processing kinematic (PPK) methods, which help make the photogrammetry process efficient and accurate.”

    Every year, thousands of tourists visit Davos in the Swiss Alps. To protect the town and the skiers, avalanche barriers were built along the steep slopes. To plan the work along the uneven rock face, a detailed 3D reconstruction of the area was needed, but getting to the survey site would be a rock-climbing feat.

    Darnuzer Ingenieure used the WingtraOne fixed-winged drone, which features a top-quality camera and a Septentrio high-performance GNSS receiver. A single surveyor took the drone to the rocky Parsenn slope during the summer season, capturing ground images — without snow — that were needed for the 3D model.

    WingtraOne PPK enabled high-precision mapping without the need for ground control points. During the flight, each image was accurately time-stamped and raw GNSS data from the Septentrio AsteRx-m2 receiver was carefully logged.

    Even in this mountainous region, where peaks obstruct the sky, the receiver delivered continuous positioning. The GNSS data was processed by the GeoTagZ software library, which used corrections from a nearby base station to generate real-time kinematic (RTK) centimeter-level positioning.

    The GeoTagZ software library incorporated Septentrio’s core GNSS algorithms to assure the best positioning performance. Accurate positioning was then synchronized with the images in the next step of the post-processing workflow.

    It only took Wingtra a few days to integrate the GeoTagZ library into its WingtraHub software package. Integration of GeoTagZ into WingtraHub simplifies mapping jobs for customers like Darnuzer Ingenieure.

    “The beauty of this solution is that the drone benefits from the receiver’s high-quality raw measurements without the need for a real-time corrections link for accuracy,” Lopez said. “The quality of the measurements comes from the technology built into Septentrio’s receivers, which is designed to be resilient to radio frequency interference and multipath. In post-processing, the GeoTagZ software enables the most accurate positioning, thanks to its high-performance RTK engine.”

    SBG Systems’ INS/GNSS post-processing kinematic (PPK) software Qinertia now covers all surveyors’ projects by offering a license dedicated to GNSS post-processing. Open to the world, Qinertia supports all major GNSS receivers and is now open to third-party inertial measurement units (IMUs).

    Qinertia has been designed to offer a comprehensive suite of post-processing software to geospatial professionals. It accepts all major GNSS manufacturers, and supports proprietary protocols from NovAtel, Septentrio, Trimble and u-blox for a straight-forward workflow.

    The full-featured post-processing software offers native support for u-blox F9 real-time kinematic (RTK) receivers, reducing the workflow to a simple “drag and drop” to guarantee data integrity and accuracy.

    Qinertia has been designed to help surveyors get the most of their surveys easily with a simple workflow, powerful quality control tools and tightly coupled algorithms. All of this is available to any surveyor with the new support of third-party IMUs or GNSS receivers. Several IMUs and inertial navigation systems (INS) have already been successfully integrated with Qinertia including Northrop Grumman’s LN-200 and LCI-100 and  the Inertial Sense µIMU.

    The new Qinertia GNSS license allows surveyors to post-process both static and kinematic GNSS data. In just a few clicks, surveyors can improve their trajectories, access RTK corrections worldwide, or even control a base-station’s precise location using precise point positioning (PPP) static computations.

    GIS and Photogrammetry. Whether they fly a UAV or drive a car, professionals can improve their image location accuracy. Qinertia has been designed to help surveyors get their GIS or photogrammetry projects way more precise, by exporting a centimetric position for each picture at the exact shutter event.

  • Septentrio PPK gets a boost with BaseFinder

    Septentrio PPK gets a boost with BaseFinder

    Septentrio’s post-processing kinematic (PPK) software has been upgraded with multi-GNSS and BaseFinder functionality. BaseFinder improves project efficiency by automatically finding the most suitable reference station data needed for centimeter-level accuracy.

    Both GeoTagZ and PP-SDK now feature BaseFinder, which speeds up survey workflow by automatically finding reference data needed for augmenting GNSS logs with sub-centimeter accuracy. BaseFinder accesses an online database of reference networks and extracts the most suitable corrections available. BaseFinder is available via an app or via an API and can be incorporated into any existing software.

    PPK is often used for ground surveys with aerial drones, allowing high precision georeferencing without the need for a real-time base station link or ground control points (GCPs).

    “Surveying without a base station will allow users to reduce costs and set-up time. With this PPK upgrade we are improving the end-user experience as well as developer experience,” said Danilo Sabbatini, product manager at Septentrio.

    The new release of this GNSS post-processing software also includes two additional GNSS constellations: European Galileo and Chinese BeiDou. Having access to all the signals from all GNSS constellations improves reference network compatibility. It also improves positioning availability in difficult environments. This is particularly important when working in areas of low satellite visibility such as near tall structures or under foliage.

    When doing photogrammetry with a drone, GNSS data is often recorded and then post-processed together with base station data to achieve sub-centimeter positioning accuracy. This base station data can be obtained either with proprietary base stations or by using base station data from a public reference network (see diagram below). Septentrio receivers are designed to bring accurate and reliable positioning to photogrammetry, aerial inspection, marine survey as well as mobile mapping.
