Abstract
A new processing approach is proposed for the ultra-orbit orbit product of International GNSS Monitoring and Assessment System (iGMAS) Analysis Center. With this approach, a length of 22 h normal equation matrix and 3 h normal equation matrix are combined into a complete one to determinate the satellite orbits, which can satisfy the 2 h submit delay required by ultra-rapid products. In addition, one more hour observed data can be used compared with the traditional method with 24 h determination and 24 h prediction. Meanwhile the user available part in predicted orbit decreases from 2nd–8th to 1st–7th h. Details and procedures of this method are introduced in this paper, as well as the connection of orbit parameters when combining the normal matrices, especially the ambiguity parameters. To assess the impact of this new approach, the user available part in predicted orbit generated from the new and the old methods for 9 consecutive days is compared to the reference orbits. The results show that compared with the traditional method, the new method can improve the accuracy of quad-constellation predicted part of satellite orbit. This method is applicable to IGS analysis center equally.
