Abstract

We performed the precise orbit determination of ADEOS-II using single frequency GPS data and reviewed the results. JAXA precise orbit determination system is called “GUTS (Global and high accUracy Trajectory determination system)”. In the 18th ISSFD, we reported that the accuracy of precise orbit determination achieved about 51cm. We compared the results with DLR’s orbit determination and SLR (Satellite Laser Ranging) data. The comparison showed that the DLR’s orbit determination was more precise than JAXA’s and there was a larger error in the along track component of GUTS results. We supposed that the difference in orbit determination accuracy between JAXA and DLR was partly due to the difference of the earth gravity potential model, and we upgraded the gravity potential model. We also corrected earth rotation parameter and redetermined the ADEOS-II orbit. The result was about 23cm. This result was precise enough for ADEOS-II, and comparable to DLR’s result.
