China launches GPS satellite, matches record for annual launches
China today completed its 20th launch in 2018, putting a GPS satellite into orbit with its Long March 3C rocket.
Twenty launches matches China’s 2016 record for annual launches, but they have done so in just over half a year. They continue on track to meet their prediction of about 40 launches in2018.
The updated 2018 leader launch standings:
20 China
12 SpaceX
8 Russia
5 ULA
4 Japan
China now leads the U.S. 20 to 18 in the national rankings.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Do the Chinese communists ignite their rockets with a four foot long wooden match jammed into each
combustion chamber like the Russian communists, or do they still rely on waterproof fuse?
Technically it isn’t GPS. Global Navigation Satellite System (GNSS) is used to describe the generic idea of navsats.
China has its own system called BeiDou Navigation Satellite System

Russia has Glonass, Europe has Galileo and India has NAVIC for the Indian ocean region. Also Japanese have QZSS to boost GPS availability in Japan and the SBAS satellites are also GPS compatible.
There is a nice app on the Google PlayStore called GNSSview that can can show all constellations in view.
Right now where I am I have 45 GNSS satellites visible.
4QZSS, 12 GPS8 Glonass, 10 beidou 6 Galileo and 5 SBAS.
