China successfully launched two satellites for the Beidou Navigation Satellite System (BDS) from the Xichang Satellite Launch Center on Monday afternoon Beijing time, the Xinhua news agency reported.
The launch means all the 24 medium earth orbit (MEO) satellites of the BDS-3 have been successfully sent into space, and the deployment of the core BDS-3 constellation system has been completed, according to Yang Changfeng, chief designer of the BDS.
“BDS now has the full capacity for global service. It will be able to provide excellent navigation service to global users,” Yang said.
China started to build the BDS-3 system in 2009. The system, independently constructed and operated by China, consists of three geostationary orbit satellites, three inclined geosynchronous orbit satellites and 24 MEO satellites.
A Long March-3A booster launched the two satellites into orbit.
The world’s launch providers were extremely busy in the first half of 2018, with China and the United States battling for the lead.
There with 55 orbital launches through the end of June, which amounted to a launch every 3.29 days or 79 hours. The total is more than half the 90 launches attempted in 2017. With approximately 42 missions scheduled for the last six months of the year, the total could reach 97. (more…)
There are a dozen orbital launches planned around the world through the end of June.
China will lead off on Sunday as it launches its Chang’e-4 lunar relay satellite from Xichang. A lunar lander and rover targeted for the far side of the moon is scheduled for launch at the end of the year.
Orbital ATK will follow with the launch of a Cygnus resupply ship bound for the International Space Station (ISS) on Monday from Wallops Island. On Tuesday, SpaceX is scheduled to launch 5 Iridium Next satellites and a pair of scientific spacecraft for NASA.
Other notable missions scheduled through June include a Soyuz crew mission and a SpaceX Dragon resupply flight. Rocket Lab is probably going to launch the first commercial flight of its Electron booster from New Zealand. However, the company has not published a launch window for the flight.
