一种动态对动态相对定位模型及试验研究

摘要

Traditional relative positioning usually needs one or more fixed reference stations .In some special applica‐tion ,the reference stations could be in motion .In order to resolve this problem ,a KINRTK model is studied by using a base‐line length constraint with three antenna configuration .The baseline and integer resolution method is given .A quasi‐KIN‐RTK experiment is done ,using the data collected on ship enroute ,the resolved baselines'lengths are compared with the pre‐determined baselines',which show that the KINREK model's baseline length errors are within 5cm .%传统的相对定位通常需要一个或多个位置固定的参考站，在一些特殊的应用场合参考站也处于运动状态。针对这种问题，给出了一种附加基线长度约束条件的三天线配置下的动对动相对定位模型，分析了该模型下模糊度和基线的求解方法，采用准动对动的试验方法，以海上航行实测数据解算三天线间的基线向量，以解算的动态基线长度误差分析动对动基线解算结果的精度，结果表明在该模型下的基线长度解算误差在5cm以内。
