What are the four global positioning systems?
- China's Beidou satellite navigation system and the United States, GPS, Russia's Glonass, the European Galileo (Galileo) and known as the world's four largest satellite positioning system.s
Does the car have its own positioning system?
- Such as high-grade cars are some, ordinary cars to buy their owns
GPS locator, tracker useful
- GPS locator can not meet your needs, if you can meet your needs, it is useful, can not meet your needs that is useless;GPS locator can provide the most basic function is to real-time positioning, you can view the current location information anytime, anywhere;Although this feature looks simple, but it can play a very big role;s
I bought a real carpenter car GPS locator, and then I clearly insert the boot how to display is not enabled? Which God knows?
- On the market most of the GPS locator is 100 meters range, if the location to be more precise, is an GPS car loan location is within 30 meters, the location is also according to the platform, if you use the GPS locator platform is not stable, it is in vain. The platform, GPS positioning platform three six five IOT is very stable.s
What is a GPS positioning system?
- GPS system compositionGPS system has three major components, namely, the space constellation, ground monitoring and user equipment. Space constellation in GPS 24 satellites distributed evenly in 6 orbital planes, orbital plane angle relative to the equatorial plane is 55 degrees, the angle between the plane of the orbit is 60 degrees, each satellite orbital plane 90 degrees, either on the satellite orbit plane than in the west adjacent corresponding satellite orbital plane the lead on 30 degrees. The average altitude of the satellite orbit is 20200km, and the satellite running period is 11 hours and 58 minutes. Each satellite every day about 5 hours above the horizon, and at the same time the number of satellites above the horizon varies with time and location are different, can be 4~11; the ground monitoring part of GPS at present mainly by the distribution in 5 ground stations around the world, including the injection station inspection station, master station and information. The space part and ground monitoring part of the GPS is the basis of the navigation and positioning of the system which is widely used by the user, which is controlled by the United States. The user equipment of the GPS is mainly composed of the receiver hardware and processing software. The user receives the GPS satellite signal through the user equipment, obtains the user position, the speed and so on through the signal processing, finally realizes uses GPS to carry on the navigation and the localization goal.s
QQ inexplicably with GPS positioning how to cancel
- There are two ways to turn off the GPS positioning function.First, in the message interface, click on the upper left corner of the personal avatar, open the menu, select the lower left corner of the "Settings" into the settings interface, in the "contact, privacy" option, close to the people can be seen".Second, into the group chat interface, click on the upper right corner of the icon of the three individuals, into the group information, close the shared location information option.So, you can turn off your location information.s
How to shield the signal of GPS vehicle locator
- Baidu GPS shield many manufacturers to sell, to open the shield also has the price of 100s
What is the role of GPS
- Other applications of GPSIn addition to GPS for navigation, positioning, measurement, the GPS satellite system space contained accurate clock time and frequency information can be released, therefore, the accurate clock space satellite based on the ground control station, the precise time and frequency of transmission is another important application of GPS, application of the control function for precise time or frequency, engineering experiments for many services. In addition, GPS can also use the meteorological data obtained, some experiments and engineering applications.The global positioning system GPS is the development of this year one of the most high-tech pioneering, its global, versatile, navigation, weather all day long timing, speed advantages will be more and more widely used in many fields. In developed countries, GPS technology has been applied in transportation and traffic engineering. At present, the application of GPS technology in China road engineering and traffic management has just started, with the development of Chinese economy, research and application of high grade highway construction and the rapid GPS technology gradually thorough, its application in road engineering will be more extensive and in-depth, and play a bigger role.s
