and providing useful information and data on time related business applications and solutions.
We are developing the time management system for the quasi zenith satellite system (QZSS),
and also carrying out precise time and frequency comparison experiments between a clock on a satellite
and the clocks on the ground using ETS-VIII (engineering test satellite 8).
