[0024] Example 1:
[0025] like Figure 1-7 As shown, the embodiment of the present invention provides a deep-water high-precision navigation positioning technology based on multi-method fusion, including aquatic positioning system, inertial navigation system, map matching positioning system, and multi-sensor data fusion positioning system, a water sound positioning system, Inertial navigation system, map matching positioning system and multi-sensor data fusion positioning system for connection fusion, need to pass the Doppler tester, the pressure sensor, the pressure sensor, the water sound positioning system is used by the multi-line navigation system before use. The transducer, the underwater transponder composition, by measuring the sound wave signal propagation time or the phase difference, underwater positioning, the information measured by the water sound positioning system can be an input as an information fusion, providing a cumulative error correction of the inertial navi...
