摘　　要：文中针对目前北斗卫星定位系统海上定位精度低,设备成本高的问题,设计开发了应用于远海定位的北斗卫星接收系统,并提出了海上定位坐标的解算方法。该系统在考虑满足海上定位需求的基础上,通过有源阵列天线和低噪声放大器实现了对北斗卫星信号的接收与放大。通过对卫星的伪距观测量,建立伪距方程,并利用最小二乘法将其线性化,最终得到海上位置信息解算矩阵。用户可以根据定位精度需求自行设置求精精度,确定迭代次数,完成海上定位信息的求解。In view of the problem of low positioning accuracy at sea and high cost of equipment at present, this paper designs and develops a Beidou satellite receiving system using Yu Yuanhai positioning, and puts forward the method of calculating the coordinates of the location of the positioning system at sea. The system has realized the reception and amplification of the Beidou satellite signal by active array antenna and low noise amplifier on the basis of meeting the demand tor marine positioning. Based on the pseudo range observation of satellites, the pseudo range equation is established, and the least squares method is used to linearize it. Finally, the solution matrix of sea position information is obtained. Users can set their own precision according to the positioning accuracy requirements, determine the number of iterations, and complete the solution of positioning iniomlation at sea. The research content of this paper is of great significance tor promoting the application of Beidou satellite in marine positioning.
