112 reinforced by secure login procedures for both GCS equipment and onboard processors, he emphasises. “The most common radios we use also utilise antispoofing technology to further resist rogue RF communications.” Anti-jamming capabilities also feature, including frequency hopping, encryption, and redundant communication links. With the latter, it can automatically switch to alternative frequencies or communication methods if interference is detected. “Additionally, onboard AI may recognise and mitigate jamming attempts by adjusting flight parameters or activating autonomous return-tohome (RTH0205) functions.” In this vein, multiple fail-safe communication protocols are used, including redundant RF, satellite (Starlink/ Iridium), and 4G/5G LTE links with automatic switching. If all links fail, the vehicle follows emergency procedures such as RTH, loitering, autonomous landing, or – if it has beyond-visual-line-of-sight (BVLOS) approval – mission continuation. In addition to the flight termination system, geofencing helps ensure safety. Customisation is possible with modular RF bands, encrypted data links, and bespoke systems for specific missions. The UAV integrates with cloud platforms like AWS and Azure for real-time data analysis. Future advancements may include AI-driven communication for intelligent bandwidth allocation. Depending on the handset and GCS selected, the maximum operating range of a Sensus L is 90 km from its take-off point. However, ISS also offers satcombased control, including Starlink Mini and other, more secure systems. The vehicles also have an onboard gigabit network for high-speed comms between connected devices, and options for 10 Gb optical fibre lines. The latter are particularly useful for data and C2 comms when the UAVs are employed in tethered operations. Environmental resistance Robustness to the operating environment is also a key consideration in material selection. “We look for materials that are corrosion resistant, have a long shelf life, and that are compatible with our machining and manufacturing techniques,” Kempley says. “They also need to meet the requirements for our standard IP ratings, ie non-porous, and have the ability to withstand consistent temperatures above 55 C.” In terms of environmental resistance, all variants are offered with an ingress protection rating of IP54 with the option to upgrade that to IP65 to ensure reliable performance in a wide range of weather conditions without limitations, he emphasises. The result is that Sensus L and the rest of the family can operate comfortably within a temperature range of -19 to +55 C, and in climatic conditions ranging from very humid to very dry. In large measure, this ability to shrug off very high temperatures is enabled by extensive cooling features integrated into the vehicle’s processing infrastructure. This helps manage heat generated by onboard electronics and power systems even in high ambient temperatures. For example, they have been flown in Kuwait, Oman, Saudi Arabia, Abu Dhabi, Canada, the Atacama Desert in Chile, and Papua New Guinea. “Depending on the rating required by the customer we have a number of April/May 2025 | Uncrewed Systems Technology In addition to the red GPR antenna, this view shows a Yelloscan lidar, twin GNSS antennas and a GBS10/350 parachute recovery system from Galaxy GRS Sensus L’s motherboard with electronics including the Cube autopilot, Microhard data link, and dual RTK GPS modules from ARK Electronics
