China's BeiDou Navigation Satellite System (BDS-3) has improved its timing service, according to a new study.
Researchers from the National Time Service Center of the Chinese Academy of Sciences analyzed the time transfer performance of BDS-3 signals. Results showed that the time transfer performance of the BDS-3 is over 50 percent higher than that of the BDS-2.
After conducting the zero-baseline common clock time comparison and other analyses, the research found that the time transfer performance of BDS-3 signals is comparable to that of Galileo and GPS.
The study was published in the international journal Metrologia.
According to the National Time Service Center, the publication shows that the center's research in BDS-3's time application has won international recognition. It also shows that BDS-3's timing service has been recognized by international experts in the field of time and frequency, conducive to promoting the international application of the BDS.

Fourth Lockheed Martin-Built GPS III Satellite's On Board Engine Now Propelling It To Orbit
Denver CO (SPX) Nov 05, 2020
The fourth Lockheed Martin-built Global Positioning System III (GPS III) satellite is now headed to orbit under its own propulsion. Following a successful launch earlier this evening, GPS III Space Vehicle 04 (GPS III SV04) separated from its rocket and is now using onboard power to climb to its operational orbit, approximately 12,550 miles above the Earth. About 89 minutes after a 6:24 p.m. EST liftoff from Cape Canaveral Air Force Station, Florida, U.S. Space Force and Lockheed Martin engineers ... read more
