Abstract
A precise geodetic measurement network using three modern space geodetic
techniques, i.e. Very Long Baseline Interferometry, Satellite Laser Ranging,
and Global Positioning System, is being established around Tokyo, Japan by
the Communications Research Laboratory. The Key Stone Project, which is the
name of the project, was started to obtain precise relative positions of
four stations using these three space geodetic techniques on a daily basis.
The system was designed to make frequent observations possible with minimum
human operations and to provide analyzed results as fast as possible. This
paper describes various aspects of new features and the performance of the
automatic geodetic Very Long Baseline Interferometry observation and data
analysis system designed for the Key Stone Project. This automated design
has allowed daily Very Long Baseline Interferometry experiments to be
conducted since January 1995 and the results to be immediately made
available for public use after each experiment.
