The packaging design has been optimised and characterised to support multi-year lifetimes. “The packing factor – how densely you can pack the PV cells into a given wing area – has been maximised as well, as that influences how much power you’re carrying.” Alta uses an overlapping design for interconnecting solar cells, which enables close to 100% use of wing area for cell integration. The company has a proprietary modelling suite built around circuit modelling software Spice, and atmospheric radiative transfer simulators for electrical layout and simulating the performance of the solar array in different conditions, including variations in environment, damage, temperature and illumination. Gladiator Technologies has developed a processing firmware suite called Velox, which is installed in all the company’s digital IMUs, gyros and GNSS-INSs. “With Velox we have created a high-speed processing solution that can achieve up to 10 kHz speeds for sampling and data output,” said Eric Yates. ”It also enables a 350 Hz bandwidth, and message latencies of less than 200 µs.” The company is also close to completing development of its LandMark 60LX IMU, which will have a 28 μ g /Hz accelerometer and a 4 º /h in-run bias stability gyro. It will weigh 125 g, measure 50 x 45 x 34 mm, and typically consume 550 mW. The new system is expected to be released shortly. “The 60LX MEMS IMU has exceptionally low-noise accelerometers and gyros,” Yates said. “Velox is also a key feature, offering high-speed processing and filtering duties. Users can configure output rates, bandwidth, baud rate and other settings to meet their particular system requirements, although we’ve found that most users prefer to configure for faster speeds and higher bandwidth.” Southwest Antennas is launching a new line of circularly polarised omnidirectional antennas. The Turbo Cloverleaf range is designed with unmanned systems and multi-antenna MIMO applications in mind. As Adam Krumbein told us, “They are going to be available for the S and C bands, and the circular polarisation can help establish a good link between the GCS and air vehicle, since polarisation mismatch isn’t there to cause comms issues, as it often is with vertical and horizontal antennas. With circular polarisation, the relative angle between the UAV and GCS no longer affects the comms link.” The antennas in the Turbo Cloverleaf range are available as left- or right-hand circularly polarised, and are typically 110- 130 mm in height. Auterion attended the exhibition to announce the latest integrations of its software solutions, including the installation of the Auterion Enterprise PX4 onto Impossible Aerospace’s quadrotor UAV, the US-1. “The US-1 can fly for two hours on electric battery power alone,” said Dr Lorenz Meier. “The PX4 is the flight control and avionics software running on the drone. The full system also runs Auterion Ground Station on a GCS tablet. “The software is based on the open source QGroundControl software architecture. The UAV is connected by LTE to Auterion Cloud Insights, which provides fleet management, automatic log analysis and management, pilot management, and real-time predictive maintenance if there is a problem with the vehicle.” Meier added that the open source nature of Auterion’s software means that integration requires minimal time and work, and that some aspects of Impossible Aerospace’s technology already use very similar software. That therefore reduces the amount of new learning required by manufacturers and test pilots. “By integrating our software onto June/July 2019 | Unmanned Systems Technology The AnyLight solar module, for HALE applications Gladiator Technologies’ LandMark 60LX IMU
