Abstract

The invention discloses a whole-sea tidal observation system based on Beidou. The whole-sea tidal observation system comprises a Beidou second-generation satellite navigation and positioning system, a Beidou satellite communication system, a shoreside base station, and a tidal observation data acquisition device positioned on a carrier in ocean; meanwhile, the invention discloses a tidal observation method for the tidal observation system; the tidal observation method comprises the following steps: determining a tide model of a sea area where the shoreside base station is located by the shoreside base station according to latitude and longitude coordinates of the tidal observation data acquisition device, determining a main tidal component type of the sea area where the shoreside base station is located, and carrying out trigonometric polynomial fitting on daylong tidal level data according to the period of the tidal component type to obtain a high-precision daily tide level curve. The whole-sea tidal observation system disclosed by the invention can be applied to any one sea area which can receive an electromagnetic wave signal of a Beidou second-generation satellite; the defect that a conventional tidal observation means only can be operated near shore is overcome, and the working range of marine tide measurement is widened; in addition, the Beidou satellite communication system is adopted for carrying out data transmission, so high data security is realized.

Description

technical field [0001] The invention belongs to the field of marine environment monitoring, and in particular relates to a method for checking tides in any sea area in the world based on the Beidou second-generation satellite navigation and positioning system and the Beidou satellite communication system. Background technique [0002] Accurately obtaining tidal information in the ocean plays a vital role in ship navigation, marine disaster forecasting, marine fisheries, and military operations. At present, the existing tide measurement methods include tide well, float type tide measurement, acoustic tide measurement and pressure tide measurement. The above tide measurement methods can only be applied to the near shore, and cannot be applied to the deep sea. With the gradual improvement of my country's Beidou satellite navigation and positioning system and the gradual maturity of Beidou single-point positioning technology, it will be applied to the tide measurement method in ...
