  • UAV Navigation provides flight-control solution for VTOL platforms

    UAV Navigation provides flight-control solution for VTOL platforms

    UAV Navigation has developed a flight-control solution specifically for vertical-take-off-and-landing (VTOL) fixed-wing drones.

    Interest in using VTOL platforms has grown in the past few years, according to the company. A hybrid between fixed-wing and rotary-wing platforms, VTOLs provide operators with versatility.

    The company’s fixed- and rotary-wing development teams worked together on the flight-control solution. Technological capabilities from other solutions — referenced navigation or the development of missions in environments without GNSS signals and under threat of jamming attack — have been incorporated in an organic way to facilitate a complete and reliable system.

    The hardware developed by UAV Navigation has the MIL-STD-810F and MIL-STD 461F certification, proving the system has been tested by an independent body that certifies its extraordinary behavior in adverse conditions.

    “Our extensive experience with fixed-wing and rotary-wing platforms allows us to know the strengths and challenges that these platforms face as a mission is performed,” said Miguel Ángel de Frutos, CTO of UAV Navigation. “Taking this as a starting point, we have managed to develop a specific solution for VTOL platforms that not only has the same technological capabilities as our existing solutions, but also enables missions to be carried out with the highest possible security.”

    One of the main challenges with VTOL platforms is the transition from vertical to horizontal flight and vice versa. UAV Navigation’s solution facilitates and automates this critical moment as much as possible, while optimizing battery use. A series of safety and emergency procedures allow the aircraft to always reach a safe landing zone and overcome possible errors in the engine.

    An adaptable VTOL software architecture allows users to customize and configure the solution through the ground control station.

    Partnership with AnsuR Technologies

    logosUAV Navigation is partnering with AnsuR Technologies to enable streaming high-definition (HD) video from small UAVs carrying a 200-kbps satcom terminal.

    With the partnership, the Asmira software solution fro AnsuR provides the ability to optimize sending video and images for satellite communications. Asmira, together with the Cobham Aviator UAV 200 and the antenna pointing solution Polar-300, provided by UAV Navigation, can deliver cost-effective high quality video transmission for small satellite platforms.

    Integrated into the platform’s onboard network, UAV Navigation’s Polar AHRS delivers the attitude and steering information of the platform so the Cobham device can establish contact with the satellite.

    The Polar AHRS, a device designed to meet the demanding needs of the aeronautical sector, includes all the necessary sensors in a compact device to provide precise information to the servos in a gimbal or an antenna, enabling its control. Once a stable satellite link is established, the Asmira software delivers HD-quality video at rates down to 100 kbps and can support SD quality below 50kbps.

    The partnership enables good-quality streaming for long-range surveillance, infrastructure monitoring and search-and-rescue missions where videos are critical.

  • Russian UAV maker launches new VTOL drone

    Russian UAV maker launches new VTOL drone

    Zala Aero Group unveiled the ZX1, a new hybrid unmanned aerial vehicle (UAV), at the 2021 International Defense Industry Exhibition (IDEX) and Conference, which opened on Feb. 21 in Abu Dhabi.

    The new drone has vertical-takeoff-and-landing (VTOL). According to Zala, it combines the best qualities of fixed-wing and multirotor types of UAVs; its configuration can change depending on the conditions of the performed task.

    Ease of operation allows the UAV system to reduce the operator’s role, decrease the amount of equipment used when performing a flight mission, and fully automate flight processes of the UAV.

    The ZX1’s onboard computer uses artificial intelligence, which makes it possible to process data in full high-definition, and transmit HD video and photos via encrypted communication channels to the GCS, ensuring the effectiveness of monitoring even before the aircraft lands.

    The VTOL design makes it compatible with existing ZALA payloads, and also allows the installation of additional surveying equipment. It can be used to perform air monitoring for the fuel and energy sector and search-and-rescue operations from sites in urban environments.

    Zala Aero Group, founded in 2004, is a Russian developer and manufacturer of unmanned aerial systems, payloads and mobile systems. It is now part of Concern Kalashnikov. Its main products are reconnaissance unmanned systems and digital solutions. Currently, more than 2,000 of Zala UAS operate within Russia. Areas of application are the protection of state borders, reconnaissance and rescue operations, monitoring of high-risk facilities and emergencies.

  • Wingtra brings wind energy to the Swiss Alps

    Site-survey preparations for a windfarm of 20 300-foot tall wind turbines might have been quite complex for a location in a 2,500-foot-high valley in the Swiss Alps.

    However, the contractor decided to use a drone with vertical take-off and landing (VTOL) capability supplied by Wingtra to speed up the work and produce highly accurate geo-referenced data. Although multirotor drones are normally used for detailed survey work, they can cover much less area than fixed-wing drones during the same flight time. Fixed-wing drones can fly longer, farther and carry more weight.

    Multicopters tend to carry more expensive, higher accuracy sensors because the sensors are not subject to potential damage from fixed-wing belly landings. Wingtra solved this problem by developing a drone with vertical take-off, the ability to transition to horizontal flight and to then land upright. When equipped with heavier, more accurate sensors, longer and more complex surveys are possible.

    The Septentrio AsteRx-m2 was also chosen for the WingtraOne drone. The AsteRx-m2 is a high-precision, multi-frequency, four-constellation, PPK, low weight and power GNSS module. The low-latency AsteRx-m2 works for both rotorary- and fixed-wing UAV applications.

    The WingtraOne VTOL drone is able to cover 400 hectares (an area of around 570 football fields) in one 55-minute flight. The resulting mapping accuracy is as high as 1.27 centimeters (0.5 inches). The drone was equipped with the full-frame 42MP Sony RX1RII camera, with seven ground control points for increased accuracy.

    The WingtraOne took off vertically and transitioned to fly horizontally at the planned 1,500-foot altitude. Each flight took about 20 minutes to plan and involved 30 minutes of flying time. The flights covered a total area of 1,100 hectares — each flight was 200–300 hectares.

    Aerial data collected from the site was converted to 3D models that allowed visualization of planned roads and wind-turbine locations in the wind farm. The data-collection workflow only took 4 hours rather than the days required with traditional surveying. Use of high-end sensors ensure survey-grade imagery and accuracy — in this case, the engineers obtained an accuracy of 3–4 cm.

    Flying in an area as difficult as the Swiss Alps to collect aerial data has been one of Wingtra’s most complicated challenges. By reducing costs and the time to complete the survey and evaluation of the proposed site, the customer was able to maintain the overall wind farm project timelines.
