The invention discloses a method and system for determining the sea depth measurement precision of a deep sea pressure gauge. The method comprises the following steps: acquiring the arrangement position of a deep sea pressure gauge; acquiring satellite orbit data during synchronous observation of the height measurement satellite and the deep sea pressure gauge and sea depth measurement data of thedeep sea pressure gauge during the topping time of the height measurement satellite; acquiring sea surface altitude difference according to the satellite orbit data and the arrangement position of the deep sea pressure gauge; according to the satellite orbit data, obtaining a satellite measurement sea surface height value at the point PCA; according to the sea depth measurement data of the deep sea pressure gauge at the peak-crossing time of the height measurement satellite, obtaining a sea depth measurement value of the deep sea pressure gauge at the moment corresponding to the sea surface height value measured by the satellite by adopting difference calculation; obtaining the measurement standard deviation of the deep sea pressure gauge, and obtaining the precision of the deep sea pressure gauge during sea depth measurement. The method can achieve the evaluation of the relative sea depth measurement precision of the deep sea pressure gauge, and is high in evaluation result reliability.
Description
Technical field [0001] The invention relates to the field of marine surveying and mapping, and in particular to a method and system for determining the sea depth measurement accuracy of a deep sea pressure meter. Background technique [0002] With the continuous improvement of human needs for precise understanding of the deep blue ocean, high-precision and large-scale depth measurement equipment has emerged. In recent years, the performance of sea depth measurement equipment has been further improved, and its measurement resolution has reached the order of millimeters when observing sea depths of several kilometers. However, the accuracy assessment of sea depth measurement equipment has long lacked effective means. This is mainly due to two reasons: On the one hand, the measurement accuracy of the pressure gauge used for deep-sea depth change monitoring is difficult to evaluate through simulated experimental environments; on the other hand, it is difficult to find high precision...
