From the following links, you can access the actual up-to-date analysis results obtained from the Key Stone Project VLBI observations. Please note that the observation and data processing system is still under development and, therefore, inaccurate results might be produced through the automatic data analysis processes, occasionally in spite of the error detection procedure. If you have any questions regarding the analysis results, please send an e-mail to us.

• Baseline Length
• Site Position
• Flux Densities of Observed Radio Sources
• Detailed Results
• Comparison of Tape-based and Real-time Data Processing Results
  Until June 2, 1997, data obtained in the daily KSP VLBI experiments were processed mainly by tape-based processing system. On the other hand, real-time data processing was performed in parallel with the tape-based data processing from April 7, 1997 until June 2, 1997. The analyzed results of two methods are compared using the estimated baseline lengths. Since June 3, 1997, the daily VLBI observations are only processed with the real-time VLBI data processing system.
