UAV Navigation, a Spanish guidance, navigation and control company in the Oesía Group, has developed the HES01, a heading estimation system for uncrewed aircraft. The company says it makes landings easier and gives a heading reference where GNSS signals are unavailable or jammed.
The HES01 combines dual GNSS signals with RTK, a built-in magnetometer and a MEMS inertial measurement unit. According to the company, this gives a heading accurate to 0.4 degrees, both standing still and on the move, without any alignment manoeuvres.
One of its main uses is recovering drones on moving platforms such as ships. The HES01 follows a landing point that moves with the vessel: RTK corrections give relative positions to the centimetre, while the inertial unit makes up for the pitch, roll and heave of the platform in waves.
Where GNSS is denied, it can work with UAV Navigation's VNS01 visual navigation system. It also keeps comparing the magnetometer with the heading from GNSS to catch errors from electromagnetic interference before they affect navigation. It is built to work with the company's Vector autopilots and GHU-100 ground control station.
