FIELD: instrumentation.
SUBSTANCE: device comprises a solid metal casing (3), inside of which there is a control module (1) with an optional GPS unit, a power supply source (2), a digital three-component accelerometer (15), a three-component magnetometer (17). In the lower part of the casing (3) there is a sliding anchor device (4), and also a stabilising device (5). The stabilising device (5) is made in the form of wings coupled with the casing (3) by means of hinged joints (6) and rubber shock absorbers (7). The power supply source (2) is equipped with a generator coupled with the stabilising device (5). The casing (3) in its underwater part is equipped with a damping device (14), made of an attachment, equipped with the even number of tabs. Tabs of the attachment are fixed to the buoy casing with the help of flat springs. Besides, even tabs are fixed as inclined downwards, and odd tabs - as inclined upwards. The optional GPS unit of the control module (1) comprises a four-channel receiver of satellite signals made as capable of simultaneous measurement of delta pseudo-ranges to four artificial satellites of the Earth. At the same time the receiver of the satellite communication channel comprises a navigation filter for buoy movement modelling. The casing (3) is equipped with elements (8) of the parachute system and a device (13) for transfer of information along radio and satellite communication channels. A digital three-component accelerometer (15) and a three-component magnetometer (17) are placed in a single body (16).
EFFECT: increased accuracy of determination of characteristics of sea wind waves.
