Embodiment Construction

[0034] The invention discloses a three-point deep-sea submersible buoy positioning method. The method is easy to implement, the measurement process can be completed in the recovery navigation process, and the actual position of the heavy block in the submersible buoy system on the seabed can be located more accurately. Lay the groundwork for recovery or salvage work. First, the data of three stations are measured and recorded. The present invention has very low requirements for the required data stations, and the measurement can be completed during the recovery navigation process, and it is only necessary to ensure that the three measurement points are not on the same straight line; secondly, Substitute the measured data into the geometric model for calculation; thirdly, calculate the target latitude and longitude and draw a schematic diagram of the measurement experiment; finally, the obtained results can be verified by experiments. Embodiments of the present invention will b...

Abstract

The invention, which relates to the deep-sea subsurface buoy positioning, provides a three-point type deep-sea subsurface buoy positioning method. Longitudes and latitudes at different positions within response distances of three releasers and corresponding ranging values are obtained; data are introduced into a designed geometric model; and calculation is carried out by a calculation program to obtain calculation values and sketch maps of a longitude, a latitude, and a depth of a weight block. A scientific and effective method that can be implemented simply and conveniently is provided for positioning work in deep-sea subsurface buoy recycling; and only with the three-point positioning, the actual position of the subsurface buoy in water is obtained and then recycling is carried out, so that time needed by recycling is saved to the great extent and the risk of subsurface buoy losing is reduced.

Description

technical field [0001] The invention relates to deep-sea submersible buoy positioning, in particular to a three-point deep-sea submersible buoy positioning method applicable to the positioning, recovery and detection of a deep-sea submersible buoy system. Background technique [0002] The submersible buoy is an important technical equipment for obtaining information on marine environmental noise. The submersible device can carry a variety of measurement and detection instruments, and can carry out long-term, fixed-point, continuous, and multi-level synchronous measurements in a relatively concealed manner under harsh sea conditions. Therefore, the submersible device has been widely used in marine scientific investigations and marine military reconnaissance Applications. [0003] Deep-sea submersible positioning: After the submersible enters the water, the weight will drift under the influence of the ocean current, and the drift distance in the deep sea increases with the de...
