94 new isolator mount also has a ‘fail-safe’ design. This allows the mount to stay captive, even if the elastomer were to fail. Fail-safe mounting is common in large, manned flight systems but notably absent among typical UAS mounts. “The UAV3004 is available now,” Schleicher said. “It offers three stiffness levels, and our applications engineers can help end-users determine and integrate the correct mount for any given air vehicle.” Aerobits discussed its new idME and idME+ systems for enabling remote identification of UAVs. They are designed to comply with the latest F3211-19 regulations on safety-critical surveillance and localisation of autonomous aircraft. “The regulations stipulate the use of wi-fi or Bluetooth Low Energy [BLE] technology,” explained Konrad Cioch. “Our Bluetooth-based devices, unlike other systems out there, can detect the remote ID and position of other UAVs from 3 km away, with typical BLE broadcast of no more than 10 dBm, as specified by RF standards. “We’ve put considerable r&d into enhancing the sensitivity of our Bluetooth receiver stations to make that possible. Further work with wi-fi reception and broadcast is planned for the latter part of this year.” The idME unit is designed to interface with Pixhawk-type flight controllers via a JST connector. For full operation, a position source, altitude meter and additional parameters are required so that it can then broadcast to surrounding aircraft and GCSs. The data for these can be obtained directly through the autopilot (and its GNSS-INS) via a MAVLink protocol interface. The idME+ is largely identical but comes with a multi-GNSS receiver and a barometric altitude sensor. It does not therefore need to interface with the UAV for anything other than power. Both systems weigh 4 g and measure 31.5 x 15.5 x 7.3 mm. In typical operation, the idME consumes 20 mA and the idME+ 60 mA. FCC and CE certification for both are anticipated in the near future. Volz Servos spoke with us about its future plans for new servo designs aimed at the fast-growing UAM/AAM (urban air mobility/advanced air mobility) aircraft market, in the wake of the company’s recent acquisition of Aircraft Electronic Engineering (AEE). AEE is an EASA-certified specialist avionics company known for developing, qualifying, certifying, manufacturing and maintaining customer-specific electronics and systems according to a range of critical regulations. “UAM vehicles require actuators in the 20-100 Nm rated torque range, which is at least three times more than the performance required by most UAVs,” said Mark Juhrig. “Volz, together with AEE, is able to design, manufacture and maintain certifiable actuators that can be shipped with an EASA Form 1-authorised release certificate. Such certifiable actuators are developed according to the RTCA DO-254 requirements for hardware development and RTCA DO- 178 standards for embedded software development. “Also, all product qualification, for both environmental and EMI ruggedness, is done according to RTCA DO-160G.” FiberPro attended the expo to showcase two new fibre-optic gyro (FOG)-based products: the FI 200C, a triple-axis IMU, and the FG 150, a single- axis gyroscope. The company’s products use the Sagnac effect to measure the velocity, rotation and acceleration of moving objects. The FI 200C is being introduced as one of the company’s lowest price-performance inertial navigation solutions. It weighs 790 g, measures 88.9 x 84.5 mm and consumes 5.5 W at normal operations (peak 8 W) on a 5 V operating power supply. Its angular rate sensor has an operating range of up to ±490 º , a bias stability within 0.5 º /hour (in ambient temperatures between -40 C and +70 C), and an angular random walk of no more than 0.025 º / √ hour. Its accelerometer has an operating range of ±10 g , a bias October/November 2021 | Unmanned Systems Technology Report | AUVSI Xponential 2021 FiberPro’s FI 200C and FG 150 fibre-optic gyros Aerobits’ remote UAV identification systems
