96 for aircraft manufacturers and integrators to customise control laws, control phases and fail-safes. The company also told us about its new Veronte MC280 motor controller for eVTOL systems, which is also compliant with DO178C and DO254. It weighs 740 g and is designed for a peak input current of 300 A (280 A maximum continuous current) on a voltage of 12-75 V. It also features redundant control inputs, regenerative braking functionality, and can be configured for sensorless control or with Hall effect sensors and digital incremental encoders. Emcore Corporation has introduced its new non-ITAR SDI170 MEMS IMU system, which integrates the company’s latest generation of solid-state hermetically sealed quartz gyroscopes and accelerometers. It can operate in ±1074 º /second and ±50 g standard linear acceleration conditions, and can be enhanced for working in ±70 g conditions. It operates with a 1 º /hour gyro bias and 1 m g accelerometer bias stability with 0.02 º / √ hour angular random walk (ARW) across a -55 °C to +85 °C temperature range and a wide vibration range. “The SDI170 enables us to deliver higher performance at lower cost, in a form factor and electrical interface that is a seamless replacement for a legacy ring laser gyro [RLG] IMU,” said David Hoyh. The company noted that it fits as a drop-in replacement for the HG1700-AG58 RLG, using the same SDLC protocol over RS-422 but with superior performance, including a 5x improvement in ARW and with an estimated 20 years of operating and storage life without needing recalibration. Expected applications include aircraft AHRSs, GNSS-aided navigation, ground surveys, mapping, UUV autonomous navigation and payload gyro-stabilisation. Emcore also told us that its SDN500 INS, SDI500 IMU and SDI505 IMU are now free from ITAR restrictions, enabling far wider exports of the systems. uAvionix has unveiled George, its first autopilot system, which has been designed around minimising SWaP-C as well as enabling type certification for integrators aiming towards compliance with current and impending UAS regulations for BVLOS flights. “George’s triple-redundant IMU includes three accelerometers, gyroscopes, magnetometers and barometers,” Christian Ramsey said. “The hardware is designed and built to RTCA DO-254 DAL C, and also meets DO-160G and MIL-810H power and environmental qualifications.” He added that George is plug-and-play compatible with all of uAvionix’s certified and uncertified products, including its truFYX GPS (certified to TSO-C145e), the ping200X (certified to TSO-C112e, TSO-C166b, and TSO-C88b) and the RT-2087/ZPX-B microIFF Mode 5 transponder (certified to AIMS MkIIB). The autopilot is an open source system based on the CubePilot solution, enabling compatibility with PX4 and Ardupilot software configurations, and weighs 80 g. “Open source autopilots benefit from tens of thousands of man-hours of engineering and testing, but as a result the open source community has lacked a path forward to be leveraged in a type certification effort,” Ramsey noted. “George fixes that problem by ‘wrapping’ the open source platform in certifiable hardware that meets typical aviation standards, and adds a DAL C safety and sensor processor. That monitors the autopilot’s and aircraft’s performances, warning the operator or taking action such as deploying a parachute if threshold parameters are exceeded.” George will be available this autumn. uAvionix also told us about its newest transponder for enterprise, professional and military UAS integration, the ping200Xr, which enables Modes A, C, S and Extended Squitter ADS-B Out. It has been developed with ease of integration and maintenance in mind, so its design combines the hardware capabilities of the company’s ping200X transponder with its truFYX’s GPS and barometric pressure sensor into a single enclosure, as well as the certifications of those systems. “That simplifies installation, and allows the customer to choose between the existing installed GPS antenna or one provided with the ping200Xr,” Ramsey added. The ping200Xr measures 72 x 27 x 10 mm, weighs 52 g and consumes 1.5 W during typical operations, or up to 4 W peak, over an input of 11-34 V. Riegl has introduced its new VUX-120 Lidar, which it says is well- suited to UAV-mounted geospatial surveys, especially low-altitude corridor applications. Such missions may include the mapping of power lines, pipelines, rail tracks and highways. “At nearly half the weight of the established Riegl VUX-1UAV or VUX-1LR models, the VUX-120 weighs only 2 kg” said My-Linh Truong. “With an FoV of 100 º , the VUX-120 can cover large swathes and only needs one pass to do so, making it suitable for use on fixed- wing UASs.” The VUX-120 has 1 Tbyte of internal storage, which the company notes is key for recording data when operating BVLOS without a live downlink, as well as a unique scan pattern consisting of scan June/July 2021 | Unmanned Systems Technology The Emcore SDI170 MEMS IMU
