Abstract

Satellite Navigation Unit has been generating the precise orbit and clock products of GNSS satellites by using MADOCA (Multi-GNSS Advanced Demonstration tool for Orbit and Clock Analysis), and been distributing to user via network routinely. On the JSS2, we aim to realize fast computation for the long-term data analysis and simulation.

Please refer to ‘MADOCA Products‘.

Reasons for using JSS2

To improve of the MADOCA products accuracy, we need to do long-term data analysis. By using JSS2, we have been expecting the reduction of the data analysis time.

Achievements of the Year

In this financial year, we just installed and tested the MADOCA. And, we confirmed that the test result was agreed with the result which calculated on the general-purpose PC in the permissible range.
