Determination of the Position of Shimosato by Lageos I and Lageos II Long-arc Analysis and Transformation Parameters between Tokyo Datum and World Geodetic System
To determine precise position of the satellite laser ranging (SLR) station at the Shimosato Hydrographic Observatory in a geocentric terrestrial reference system, or a world geodetic system, 13 year Lageos SLR data obtained at global SLR network were analyzed. Combining 1-year solutions of Lageos l and Lageos ll, a terrestrial reference frame based on the world geodetic system was established. This reference frame is compatible with International Terrestrial Reference Frame 96 (ITRF96) but the coordinate values of Shimosato is closer to ITRF 97. Position of the datum origin of the Tokyo Datum was connected to Shimosato using SLR and GPS techniques. The transformation parameters were re-determined from the coordinate values at the datum origm. The parameters give only several-cm difference from those determined by the Geographic Survey Institute, though these are independent results derived from different techniques.

| Summary: | To determine precise position of the satellite laser ranging (SLR) station at the Shimosato
Hydrographic Observatory in a geocentric terrestrial reference system, or a world geodetic system,
13 year Lageos SLR data obtained at global SLR network were analyzed. Combining 1-year
solutions of Lageos l and Lageos ll, a terrestrial reference frame based on the world geodetic system
was established. This reference frame is compatible with International Terrestrial Reference
Frame 96 (ITRF96) but the coordinate values of Shimosato is closer to ITRF 97. Position of the
datum origin of the Tokyo Datum was connected to Shimosato using SLR and GPS techniques. The
transformation parameters were re-determined from the coordinate values at the datum origm.
The parameters give only several-cm difference from those determined by the Geographic Survey
Institute, though these are independent results derived from different techniques. |
