摘要
在卫星时钟、系统时钟、用户接收机时钟同步为前提假设的基础上,描述了用户接收机定位的数学原理;又在以上时钟非同步条件下建立用户接收机位置定量求解模型和算法,在线性化的基础上,用迭代法进行位置求解.为定位软件的设计提供了理论依据.
The paper introduces the basic mathematics principle of receiver positioning based on the condition of synchronization of satellite time, system time and the receiver time. Then a mathematics model is established and a position calculating method is proposed based on the situation that the above three timing factors are asynchronous. After the linearized, the receiver position equation is resolved by iterative computations. The paper establishes a theoretical basis for the design of positioning software.
