precision. satellite navigation capable of global coverage is called a global navigation satellite system. the electronic receiver analyzes the time and the distance from each of the satellites to reach the user's receiver antenna. the fourth satellite in the navigation system helps in removing the ...
There is not much of a difference between the two other than accuracy. GPS has a constellation size of 31 satellites, whereas the new BeiDou will have about 35 of them. When fully operational (by 2020), BeiDou Satellite Navigation System is expected to provide moreaccurate location servicesthan...
What is Beidou? Beidou is a navigation (导航) satellite (卫星) system. It is developed by China. China is the third country in the world to have its own navigation satellite system. With Beidou, China no longer has to depend on foreign systems. This is very impormant for national safety...
The Beidou Navigation Satellite System will be more powerful than any other navigation satellite system in the world.Yang Changfeng is a designer of Beidou.He said the system can notice the sway(晃动)of a building in strong winds. Beidou has brought much benefit(益处)to our lives.In many cit...

GPS, or the Global Positioning System, is a global navigation satellite system that provides location, velocity and time synchronisation. GPS is everywhere. You can find GPS systems in your car, your smartphone and your watch. GPS helps you get where you are going, from point A to point B...
Introduction to Global Positioning System: The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth. Global Positioning Systems usually refer to the GPS receiver. It was developed by th...
What is GNSS? The term GPS is now so familiar to the general public that it has become synonymous with any satellite navigation system—but we need to be careful. The term GPS is actually the name of the system created by the American military, and stands for Global Positioning System. Th...
For example, the 22 satellites China just sent up are part of the Beidou Navigation Satellite System (北斗卫星导航系统). Shared bikes that use BeiDou chips (芯片) can have more accurate (精准的) positioning, making them easier to...
