| titleOfInvention | A Polar Grid Inertial Navigation/Ultra-short Baseline Compact Navigation Method |
| abstract | The invention provides a polar area grid inertial navigation/ultra-short baseline tight combined navigation method. The method uses an inertial navigation system as a basic navigation device, adopts a grid coordinate system as a polar area navigation coordinate system, and introduces an ultra-short baseline positioning system to measure Carrier position, based on the Kalman filter, based on the slant range information of the ultra-short baseline positioning system and the more primitive phase difference information, the polar grid inertial navigation/ultra-short baseline tight integrated navigation method is designed to provide real-time and continuous high-speed navigation. Precision navigation information. This method not only overcomes the error amplification caused by the convergence of the meridian in the polar region, but also can effectively suppress the navigation error of the inertial navigation system, improve the navigation accuracy, and better ensure the reliability of the navigation system without destroying the autonomy of the navigation system. Provide high-precision navigation information for polar vehicles. |
