陆标定位问题解算

The Solution of the Problem of Fixing by Landmark

随着船舶定位自动化程度的提高,陆标定位问题解算越来越引起航海界的重视。本文对常用的方位定位、距离定位、水平角定位解算问题进行了探讨,列出了位置线线性方程组(陆标定位数字模型),通过解算方程组,可直接得到船位坐标((φ,λ),对实现陆标定位解算自动化有一定参考和实用价值。

With the improvement of the automaticity of Ship's position fixing. The solution of the problem of fixing by landmark is becoming more and more concerned about by the navigation community. This paper presents a research into the solution of the problems of fixing by cross bearings, fixing by distances and fixing by horizontal angles. It also gives the linear equation group of Lop (Line of position), the mathmatical model of fixing by landmark. The latitude and longi tude of a ship's position can be obtained directly with the solution of the linear equation (?)oup. It is of both referential and practical value for the realization of the automation of f(?)gy by landmark solution.
