Japan launches advanced GPS satellite into orbit

Tokyo, Oct 26 (IANS) Japan has successfully launched a new navigation satellite into orbit that will replace its decade-old navigation satellite.The satellite, QZS-1R, was launched onboard H-2A rocket that lifted off from the Tanegashima Space Center at 10.19 p.m. on Monday night, Mitsubishi Heavy Industries said in a statement. The company builds and operates H-2A rockets the Japan Aerospace Exploration Agency (JAXA). QZS-1R is a replacement for Quasi-Zenith Satellite System 1 satellite first launched in 2010. "It was really beautiful launch," the company said in a tweet after a successful lift-off. "H-IIA F44 flight proceeded nominally. Approximately 28 minutes 6 seconds after launch, as planned, the payload separated from the launch vehicle," the statement said.The official QZSS website lists four satellites in the constellation: QZS-1, QZS-2, QZS-3 and QZS-4, Space.com reported.The QZSS constellation will eventually consist of a total of seven satellites that fly in an orbit passing through a near-zenith (or directly overhead) above Japan, and QZS-R1 is meant to share nearly the same transmission signals as recent GPS satellites, according to JAXA. It is specially optimised for mountainous and urban regions in Japan, JAXA said.Mitsubishi's H-2A 202 rocket launch system has been operational since 2003 and has sent satellites to locations such as Venus (Akatsuki) and Mars (Emirates Mars Mission). The latest H2-A rocket launch is the first since November 29, 2020, when Japan launched an advanced relay satellite with laser communications tech into orbit, the report said.
