Quasi-Zenith Satellite System Constellation ← QZS-4 QZS-5 →

QZS-1R is a Japanese navigation satellite consisting part of the Quasi-Zenith Satellite System (QZSS). QZS-1R will replace the QZS-1 (Michibiki-1) satellite launched in September 2010. QZS-1 has a design life of ten years. As QZS-1 is an experimental satellite, it did not broadcast the MADOCA (Multi-GNSS Advanced Demonstration tool for Orbit and Clock Analysis) signal, which can be used for centimeter-order navigation.^[2]^[3] With the launch of QZS-1R, all satellites of QZSS will be capable of transmitting in the MADOCA signal, reaching operational capacity.^[2]

Satellite

QZS-1R is the fourth operational Quasi-Zenith Satellite to be launched. The design of the satellite is based on QZS-2 and 4, with minor differences such as an increase in the number of temperature sensors on board.^[4]^[5]

Launch

QZS-1R was launched on 26 October 2021 by Mitsubishi Heavy Industries.^[4]
