| Outline of Final Research Achievements |
Improvement of terrestrial reference frames and gravity field of the Earth was investigated through precise orbit determination of low-Earth-orbit satellites. A simulation study is carried out to find out the best position for a new SLR (satellite laser ranging) tracking station, and we found the high-latitude area in the southern hemisphere is effective. We also focused on the inter-annual variation of Earth gravity field derived from SLR data, and, by matching it with atmospheric, oceanic, hydrologic and glacial models, the primary cause was found to be changing in time.
