Positioning Accuracy Super GPS! Purple Show Sharp New Push Four In One Navigation Chip: Support Beidou 3!

Jan 22, 2019

BDS is a global satellite navigation system independently built and operated by China and compatible with other global satellite navigation systems.
On December 27, 2018, the state council information office announced the completion of the basic beidou 3 system, which will provide global services from now on. This marks the expansion of the service scope of the beidou system from regional to global. The beidou system has officially entered the global era and become a truly global satellite navigation system.
The accuracy and reliability of beidou 3 have been greatly improved, with the positioning accuracy of 2.5 to 5 meters, the speed measurement accuracy of 0.2 meters/second, the timing accuracy of 20 nanoseconds, and the design life increased from 8 years to 10-12 years.
Compared with GPS, the third generation of beidou has the technical advantage of late development. The space segment USES three kinds of orbital satellites to form a hybrid constellation. Compared with other satellite navigation systems, high-orbit satellites have stronger anti-blocking ability, especially in the low-latitude areas.
In addition, beidou-3 can provide navigation signals of multiple frequency points, and improve service accuracy through the combination of multi-frequency signals.
According to the plan, by 2020, beidou iii will have 35 satellites and be fully completed, making it the world's largest satellite navigation system.
