QZS 1R is a navigation satellite of Japan in the Quasi Zenith satellite system. The QZS1R will replace the QZS1 satellite launched in the year 2010. QZS1 has a nominal lifespan of 10 years. QZS1 is a satellite which is experimental, it does not transmit Multi GNSS Advanced Demonstration Engine for Orbital and Clockwise Analysis (MADOCA) signals, which can be used for centimeter-by-centimeter navigation. With the launch of QZS1R, all QZSS satellites will be able to transmit MADOCA signals, reaching their operating capacity.
Highlights
The QZS1R is the 4th operational quasi-zenith satellite to be launched. The satellite design is based on QZS 4 and 2, but there are some differences which are minor such as an increased number of temperature sensors on its board.
QZS 1R was launched from the Tanegashima Space Center. QZS 1r has been designed to have a life span of 15 years.
The QZS1R was installed on the H IIA rocket which has been made by the Mitsubishi Heavy Industries. The flight proceeded as planned and the payload was separated from the launcher after take-off.
Conclusion
QZSS started service on four satellites in the year 2018. The Japan Aerospace Exploration Agency plans to deploy seven satellites by the year 2023.
