Abstract:	We have performed a preliminary demonstration of the operation of a real-time system for kinematic survey using GPS. The GKSS system tested in March 1992 at Shimonoseki, Japan showed relative horizontal position- ing accuracy of about 5 cm in real time. The M&try of Transport is planning to use the final version of this system for surveying and dredging of waterways in the surrounding region of Japan. The Phase I demonstration GKSS comprises two Furuno GPS receivers with 6 parallel C/A code and carrier chan- nels, a color plotter for real time display, and a fiber optic referencelinl.Fotthisp~ofthe&~nstrationambigu- ity resolution was done on a fixed known baseline and real time kinematic survey was performed overarange of about 30 m. Development and testing of hardware and software algo- rithms for the Phase II program are in progress. For this effort we plan to demonstrate on-the-fly ambiguity resolu- tion using a least squares technique. The demonstration will be performed in the Sea of Japan over a range of S-20 km. The new hardware, algorithms, and plans for Phase II aredescrihed.
