| 摘 要： | 为了实现终端定位不依赖于GPS，解决终端自主定位导航，针对双模手机终端，提出了一种根据终端位置环境和运动状态，利用卡尔曼滤波的终端自主定位算法。采用该方法可以为用户提供高精度、高概率和高保密性的定位业务，Matlab仿真表明该方法具有终端信道环境和运动状态的自适应处理能力，并提出了相应的措施来进一步提高定位精度。

| Abstract: | Aiming at the dual-mode mobile terminal, this paper presents a Kalman filter-based terminal autonomous positioning algorithm in accordance with environment and movement, which realizes the terminal positioning to be independent of GPS and the terminal autonomous positioning navigation. This method has broad application with high-precision, high probability and high confidentiality, and Matlab simulation shows that it has adaptive processing ability by the terminal channel environment and movement state. In addition, the corresponding measures are given for further improvement of the positioning accuracy. |
