| 摘 要： | 研究和分析了脉冲星定位方法中的绝对定位法。通过一系列的公式和图表详细分析了定位算法的理论依据,同时还对整周模糊度问题的解算进行了研究。最后,利用MATLAB建立了一个简单模型,对定位算法进行仿真。结果表明定位准确度与星载原子钟准确度、脉冲星相位模型准确度以及相位观测误差有直接联系。

| Abstract: | The method of Absolute Position Determination is studied and analyzed mainly.A series of formulas and pictures are used to analyze the theory foundation of pulsar positioning.At the same time,the ambiguity problem and the solving method are studied.In the end,a simple model using MATLAB is built to simulate the method of pulsar positioning.The result show that the positioning error is tightly connected with the atomic clock quality,the error of X-ray pulsar phase model and the error of observation phase. |
