摘要
Abstract
Inertial navigation system has many advantages such as strong independence, high update rate, good realtime performance, but the system error will accumulate with time. GPS will limit the error within a certain range, but the data update is slow and vulnerable to outside interference. Low-cost navigation system, which consists of IMU, GPS and magnetic heading meter, is becoming a research hotspot. A low-cost small AHRS is consructed. In order to apply theory into practice, taking into account the impact of time delay on the system, a 10 dimensional Kalman filter for navigation is designed. The actual measurement data are used to simulation. In a series of ground lest, it is shown that the system accuracy and stability meet navigation requirements.关键词
