Main map
Surface drifting buoys are mainly used in Marine resources development, Marine environment monitoring, Marine ecological protection and Marine scientific research . To be specific, the drifting buoy is put into the sea by ship or aircraft. The surface drifting buoy drifts with the current, and uses satellites (such as Beidou, Iridium) or wireless real-time system to locate and monitor some data of the current and wave in real time. After collecting these data, it is timely transmitted to the designated software platform and data center. It provides important information support for the Marine research of scientific researchers. Its advantages include: small size, light weight, easy to put and recover; Strong continuous working ability, can provide long-term, continuous observation data; Its structure is mainly composed of solar energy or battery power supply system unit, wireless communication equipment unit including data acquisition and transmission, corrosion resistant floating body unit these 3 parts. It is generally round in appearance, so as to be better suitable for the working environment in the deep sea or the far sea. The design mainly takes into account the principle of ocean wind and wave, and adopts the Lagrange method to measure the surface velocity on a large scale and track the trend of ocean current . The data is transmitted by UHF transmitter. The system is controlled by microcomputer. It is widely used in various experiments in the Global atmospheric research program, such as the Atlantic test, the North Pacific test and the first phase of the Global Atmospheric Research Program global experiment.

Wave drifting buoy is a small buoy measurement system that uses the principle of gravitational acceleration to measure waves. It can obtain real-time wave height, wave period, wave direction, one-dimensional energy density spectrum, two-dimensional directional spectrum, and spectral characteristic parameters of wind waves and swells. At the same time, it can invert wind speed, wind direction, and other data based on the wave spectrum.
