China launches another GPS-type satellite

China today successfully launched another of its Beidou GPS-type satellites, using its Long March 3B rocket.

I found this data point from the link interesting:

Real-time, stand-alone Beidou horizontal positioning accuracy was classed as better than 6 meters (95 percent) and with a vertical accuracy better than 10 meters (95 percent). …[However, t]he system will be dual-use, based on a civilian service that will provide an accuracy of 10 meters in the user position, 0.2 m/s on the user velocity and 50 nanoseconds in time accuracy; and the military and authorized user’s service, providing higher accuracies.

New commercial GPS units will eventually add the Beidou constellation, and when combined with data from the U.S, Russian, European, and Indian systems, will likely get accuracies even higher.

The leaders in the the 2020 launch race:

5 China
4 SpaceX
2 Arianespace (Europe)
2 Russia

The U.S. still leads China 7 to 5 in the national rankings.

China launches two more Beidou GPS-type satellites

The new colonial movement: China today used its Long March 3B rocket to launch two more Beidou GPS-type satellites.

With this launch China has successfully matched its predicted number of launches for 2019, a number that it should exceed with several more launches scheduled before the end of the year.

The leaders in the 2019 launch race:

30 China
20 Russia
12 SpaceX
7 Europe (Arianespace)

China now leads the U.S. in the national rankings 30 to 25. These numbers should change later today, as SpaceX has a commercial launch scheduled.

China today used its Long March 3B rocket to launch two more GPS-type satellites in its Beidou constellation.

The leaders in the 2019 launch race:

17 China
14 Russia
10 SpaceX
6 Europe (Arianespace)

The U.S. continues to lead China in the national rankings 19 to 17, but China has been creeping up.
