| titleOfInvention | Integrated high-precision underwater inertial navigation and Doppler velocimeter combined navigation system |
| abstract | The invention provides an integrated high-precision underwater inertial navigation and Doppler velocimeter combined navigation system, comprising: a casing, which is fixedly installed on the aircraft, and has a cylindrical structure with closed ends, and is fixedly installed inside the casing. There are DVL and SINS; signal processing circuit, which is fixed inside the housing and connected to DVL and SINS by signal, the signal processing circuit is calculated based on the velocity value measured by DVL, the acceleration value and angular velocity value measured by SINS through the built-in navigation algorithm. The speed value, position, and attitude information of the aircraft in the navigation coordinate system are sent to the external device. The signal processing circuit adjusts the working state based on the control instructions sent by the external device, such as starting or stopping work; at least one signal interface is provided in the shell. It is used to realize data transmission between the signal processing circuit and external equipment. The integrated navigation system of the present invention only needs to calibrate the installation declination angle between the DVL and the SINS once. |
