基于概率统计模型的测控通信链路计算方法
Calculation Method of TT&C Communication Link Based on Probability Statistics Model
摘要
Abstract
In view of the low confidence of the current measurement and control communication link calculation method,this study analyzes the traditional analysis method of measurement and control communication link,and puts forward a calculation method of measurement and control communication link based on probability statistical model.According to the characteristic parameters of triangular,uniform and Gaussian distribution and probability density function,the forward and reverse tolerances of measurement and control communication links are calculated,and the calculated values under different confidence degrees are obtained.The calculation process is illustrated by taking the estimation of the operating distance of the measurement and control equipment and the calculation of the EIRP(Effec-tive Isotropic Radiated Power)of the synchronous orbit satellite as examples.The calculation error of EIRP is reduced from 14.8%to 1.47%,and the estimation error of action distance is reduced from 12.35%to 1.84%,which proves that the link calculation method can effectively improve the accuracy of link prediction.关键词
