Our ARC-Landing radar system is a vital part of supporting the autonomous landing of an Uncrewed Aerial System (UAS) onto a vessel. The UAS will have completed a mission, such as ship-to-shore (or port-to-ship) drop, last mile resupply in a military mission, or an offshore windfarm inspection, then the UAS would need to land, onto either a moving vessel or landing pad, possibly in a GNSS denied environment.
Our Active Radar Cooperating (or ARCTM) technology provides a localisation capability based upon direct radar range measurement, that is independent of satellites and invulnerable to jamming mechanisms, making it a very resilient landing system that you can depend on.
An ARCTM primary radar, installed onto the UAS, will actively cooperate with ARCTM secondary radars on the moving vessel, enabling relative positioning during the critical approach and landing phases of drone flight, through our ARC-Landing radar system. The ARC Primary reports the range, bearing, elevation and ID to other ARC Secondary radars on or around the landing zone, whilst ignoring radar reflections from background infrastructure. The ARC secondary radars on the vessel can help provide the roll, pitch and heading of the vessel, all vital information that is required when you need it most.
Each ARC device is configured with a unique code that is reported over the radar carrier frequency. This supports ‘Default Silent’ technology as the ARC remains silent, none transmitting, until interrogated by a compatible radar in a recognised encoded band, critical where electronic radio stealth is required such as in Emissions Control (EMCON) environment.
Automation removes the need for highly skilled and scarce offshore drone pilots and hence greatly reduces the costs of offshore windfarm maintenance and ship-to-shore or port-to-ship operations. Our radar system also enables critical military logistics to take place, ensuring that the key assets reach their destination in all weather, day, or night.
ARC-Landing can be used in conjunction with RadarAwareTM, our micro radar, which enables a drone to detect objects in the flight path, supporting the safe operation of drones in and around wind turbines, high-value assets, or infrastructure as they are surveyed.
It provides collision avoidance measurements in all weather conditions and minimises costly damage to the high-value assets, minimising time offline as well as providing peace of mind to the asset owners.
