72 Show report | Intergeo 2022 “That in turn created a gap between our Spatial FOG Dual, which is a traditional GNSS-aided FOG, and the Boreas range; the D70 fills that gap. It has the D90’s SWaP, and can still do the north-seeking gyro-compassing that the D90 does, but it is far less expensive, with the caveat of having slightly lower performance. “We specifically made it for clients who said they didn’t require as much accuracy but very much needed to save development costs, and keep on functioning robustly in GNSS-denied environments such as mining, offshore and some defence applications.” The D70 is a 2.5 kg unit measuring 160 x 140 x 115.5 mm. It integrates the Advanced Navigation Aries GNSS receiver with GPS L1 and L2, GLONASS L1 and L2, Galileo E1 and E5b, and BeiDou B1 and B2, as well as the WAAS, EGNOS, GAGAN and QZSS SBAS aiding services. It has an update rate of up to 20 Hz, a timing accuracy of 20 ns, velocity accuracy of 0.05 m/s and unaided horizontal position accuracy of 1.2 m (0.5 m with SBAS; 1 cm with RTK). Its gyroscope has a range of ±490 º /s, a bias instability within 0.01 º /hour, an initial bias within 0.05 º /hour, and an angular random walk of less than 0.005 º / √ hour. Its accelerometer meanwhile has a range of ±15 g , less than 7 µg bias instability, within 100 µg initial bias, and less than 23 mm/s/ √ hour of velocity random walk. With dual GNSS, the D70 outputs headings accurate to 0.01 º , while also giving pitch and roll to 0.01 º , and heave to 2% or 0.02 m (whichever value is greater), all at a rate of up to 1000 Hz. Maxon showcased its latest electric motors optimised for low-SWaP, cost-effective and robust propulsion on uncrewed aircraft. Of particular note was its ECX 32 UAV flat motor, which is 32 mm in diameter, 18.5 mm tall and 47.9 g in weight, while producing up to 1 kg of thrust force (or 105 W of power output) continuously. “Developing the ECX 32 was based closely on a proven design from our newest industrial flat motors, whose base technology has had around 20 years of use,” said Marco Sicher. “With sufficient simulation based on pre-existing data, we were able to strip down weight, increase performance and even make it run as a sensorless device – since most industrial motors use encoders or Hall effect sensors to operate – but we’re still able to produce the ECX 32s with our existing manufacturing lines, and validate their reliability in our existing quality control and testing facilities.” Maxon also plans to bring out two more sizes of electric motor in the next few months. One, the ECX 42, will be 42 mm in diameter; the other will be smaller, at 22 mm across, with both designs being based on the ECX 32’s architecture. “These new motors extend Maxon’s UAV propulsion motor portfolio further, and bigger motors are available as well – specifically our EC69 and EC87 flat UAV motors,” Sicher added. YellowScan spoke with us about its new Voyager solution, its latest product and one that integrates the Riegl VUX-120. “The Voyager is intended for integration on UAVs and light piloted aircraft, with customers in need of not only precision but also cost efficiency, high survey altitudes, and wide survey ranges, all with a high-density point cloud,” explained Morgane Selve. It weighs 3.5 kg, excluding battery, and is capable of recording 1.5 million points per second over a 100 º FOV (with up to 15 echoes per shot), each measurement having a 0.5 cm precision and 1 cm accuracy. Meant for UAVs as well as light crewed aircraft, the Voyager has a maximum operating altitude of 440 m AGL. Its users can choose to integrate either the APX-20 UAV or AP+ 50 Air from Applanix as a GNSS inertial board, and it can be powered using its own battery for up to an hour, or the operator can provide external power for the 55 W it requires through the Fischer connector for longer operations. Applanix POSPac UAV/MMS and YellowScan CloudStation software help facilitate post-processing, visualisation and analysis of gathered point cloud data. Tallysman presented three new GNSS antenna products it said are key to accurate mapping and survey missions. First was the IP67-housed SSL990XF, which uses a derivative of Tallysman’s patented VeroStar antenna element to provide full frequency coverage of available GNSS and L-band correction services. The SSL990XF is 63 mm in diameter and 28 mm tall, while weighing 50 g. It has an average phase centre variation of 4 mm or lower for all frequencies and overall azimuths and elevation angles. It supports GPS/QZSS L1/L2/L5, QZSS December/January 2023 | Uncrewed Systems Technology Maxon’s ECX 32 flat electric motor for UAVs
