An ARC-LoiterTM system comprises a primary radar mounted on the UAV and a network of secondary radars installed at the target location. The Primary device accurately measures the range and direction of the secondary devices and uses this information to provide a precision loiter target position to the UAV flight controller via the MAVLink protocol.
This target point is constantly updated, allowing the UAV to maintain its position while tracking the movement of the ARC Landing Pad constellation, such as in the case where the landing pad is installed on a moving vehicle or ship. ARC-LoiterTM also makes sure that the UAV remains stationary even if the landing pad is lifted, demonstrating the system’s ability to effectively compensate for roll and pitch movements, as seen on moving or unstable platforms.
