| 摘 要： | 针对单历元RTK定位中受到卫星升起、周跳频发等外界条件干扰时,整周模糊度长时间不能固定,严重影响RTK定位实时精度的问题。文中提出一种用载波相位约束整周模糊度的方法来提高模糊度固定率、Ratio值和解算精度,并且结合GPS单系统、GPS/GLONASS双系统两组实测数据进行未加入和加入载波相位约束整周模糊度的比较实验。结果表明该方法可行。

| Abstract: | When external factors such as the rising satellite and frequent cycle slips interfere with the process of single epoch RTK positioning ,the integer ambiguity cannot be fixed within long time ,which severely impacts the RT K positioning accuracy .Aiming at the problem mentioned above ,this paper puts forward a method of using carrier phase to constrain integer ambiguity ,in order to improve the fixed rate of ambiguity ,the value of the Ratio ,and the calculates precision .Additionally ,the method proposed is adopted to conduct the experiment for the measured data of GPS and GPS/GLONASS system ,and then to make a comparison with the method without adding the carrier phase constraint .The results indicate that this method is feasible . |
