French Exail Unveils Marins M1 Navigation System, Keeping Naval Drones on Course Without GPS
Exail unveiled Marins M1, a compact fibre-optic gyroscope inertial navigation system designed for small naval craft and unmanned surface and underwater vehicles. The 4.5-kilogram unit consumes 13 watts and is rated for position drift of one nautical mile after three hours without external aiding. Its specified heading accuracy of 0.01 degrees applies with GNSS assistance. Its intended applications include rigid-hull inflatable boats, interception craft and patrol vessels operating when satellite-navigation signals are jammed, spoofed or unavailable. The system extends Exail's Marins range to smaller platforms whose limited space, weight and electrical capacity constrain installation of larger navigation equipment.
