from the news foreign. Announced: The French SEABER company has developed a Raven compact underwater UAV for detecting sea mines. The device is able to operate autonomously under water for up to eight hours. Report (quote): “During mine operations, Raven can examine potentially mined areas and record the coordinates of suspicious objects. This information can later be used by divers or special underwater vehicles to inspect and clear mines. The Raven can be equipped with a side scan sonar that creates an acoustic image of the bottom. SEABER offers two changes to the UAV. The SCAN-MAG version received a magnetometer for searching and locating metal objects underwater. Another option, SCAN-LUMEN, is equipped with a high-resolution camera and a lighting system with a power of 24 thousand lumens. This equipment allows you to perform a visual inspection of previously found objects and determine their nature. Raven weighs 13 kg, length - from 131 to 137 cm, and body diameter - 12 cm. It can dive to a depth of 300 meters, reach speeds of 3 to 6 knots and operate autonomously for up to eight hours. One operator is enough to launch. One of the features of the UAV is SEABER's proprietary inertial navigation system, which works in conjunction with a Doppler bottom speedometer. The manufacturer claims a cumulative position error of less than 0.2% of the distance traveled during movement in a straight line. Before diving, the UAV determines its position using a satellite receiver with two antennas, which, according to the manufacturer, increase resistance to electronic interference. Underwater communication is provided by an acoustic modem, which allows commands to be transmitted and the device to be tracked at a distance of up to 2-3 kilometers.
