As of December 2021, initial on-orbit testing (IOT) and tuning of the precise orbit determination (POD) function in the ground control segment was ongoing. QZS-1R is the first QZSS satellite that will transmit the L1 C/B signal, splitting the power spectrum at the L1 center frequency by adopting BOC modulation on the existing C/A signal, to mitigate interference into the GPS L1 C/A signal. C/B signal transmission was verified during the IOT phase. QZS-1R will transmit the C/A signal continuously until QZS-5, 6 and 7 are launched and the noise floor increased.
The launch of QZS-1R was a milestone toward a sustainable national infrastructure for Japan.
というような書き出しで、持続可能な日本のQZSS衛星セグメントの増強方針と、増強1号機QZS-1Rの特徴点と現況が長文でまとめられています。ロシアとウクライナの戦争が深刻化しつつあるタイミングで、東アジアとオセアニアをしっかりとカバーする日本のQZSS増強計画が、代表的英語誌にオンライン掲載されたことは大きな意義があるでしょう。
