- Q: I drive a friend's car, I want to know if his car is a satellite positioning system, in the absence of his case, how can I know?
- Correct upstairs:1 car butt probe is reversing radar or camera, and GPS unrelated.2.GPS general built-in antenna. In short, the outside can not see.3 large screen LCD screen is a necessary condition for GPS, but not a sufficient condition...Conclusion: depending on the host system interface there is no GPS menu.
- Q: Is the GPS positioning system based on electromagnetic waves?GPS system depends on electromagnetic wave location. Is this the right or wrong?
- GPS global satellite positioning system consists of three parts: the space part - GPS constellation; ground control part - ground monitoring system; user equipment Part - GPS signal receiver
- Q: My mobile phone is Samsung, why can not locate GPS positioning
- According to your description, it is recommended that you try the following:1 shutdown to try to open the phone.2 when the weather is clear, try to search more than 3 satellites, if the search is not possible with the satellite weather, location, buildings.3 if you can not search the satellite, you can download the High German navigation map data packets to the phone, click on the following link http://c.autonavi /club/update/ please try to re map the package.4 if not successful, it is recommended that you download other navigation software to try.
- Q: Phone can not locate GPS
- No Rev GPS determine the GPS module damage to determine the brush bar
- Q: At present, the accuracy of civil GPS in the end is how much?
- GPS general civil 3M accuracy, military 0.3m. Carrier positioning speed is slow, regardless of civilian or military, precise point positioning, then more than half an hour, if the observation time is long enough to reach mm level accuracy. In addition to differential positioning, accurate location is known one or several points, for those who point to be modified using the location information of several points, can use the mobile phone signal, radio data transmission to the designated station, which quickly and accurately obtain the coordinates of points to be determined, but it is limited to a certain extent the.The positioning accuracy is measured by the coordinate (x, y, z) and reference (ellipsoid, the 3D coordinates of the human definition of direction) of the point on the real coordinates of the gap between the actual coordinates cannot be obtained, the general accuracy is obtained by using the mathematical method of valuation, the probability and statistic.
- Q: GPS locator what brand is better? What is the most stable platform?
- 1, to say the GPS locator what brand is better, this is too difficult, now on the market GPS brand to innumerable locator, what brand is good, or after their actual use to know.2, while the GPS locator to normal use, or to rely on a powerful query platform, this platform must be stable, and now on the market a lot of small brand platform or third party software to build a platform, or just build, this is not their own R & D team, is to hang a business, so everyone in the choice must see clearly3, take the use of my own, I used an car locator rice technology, quality can also, mainly is the auto search platform, online platform, more practical, most of the function of our appetites, some people to look at the proposal
- Q: My friend bought a car to install satellite positioning system I am interested in my friend explained that I would like to ask who knows the professional interpretation (product principle) who knows who
- It can be seen that the role of the GPS navigation satellite system is to continuously transmit navigation messages. However, because the user receives the clock and satellite machine using a carrier clock may not always synchronized, so in addition to the 3D coordinates of X, y, Z users, but also the introduction of a t that is the time difference between the satellite and the receiver as unknown, and then use the 4 equation the 4 unknowns out. So if you want to know the location of the receiver, at least to receive the signal of 4 satellites.The GPS receiver may receive for accurate timing information to nanosecond time; for forecasting ephemeris in the next few months which the approximate location of the satellite; used to calculate the required positioning satellite coordinates of the broadcast ephemeris, the accuracy of several meters to tens of meters (each satellite is different at any time change) and GPS system information; such as satellite status.The GPS receiver can get the distance from the satellite to the receiver by the measurement of the code, because it contains the receiver satellite clock error and atmospheric propagation error, it is called the pseudo distance. The pseudo distance measured by the 0A code is called the pseudo distance of the UA code, the precision is about 20 meters, the pseudo distance measured by the P code is called the pseudo distance of the P code, and the precision is about 2 meters.
- Q: What is the meaning of the GPS locator LBS?
- Location based service, by means of radio communication network or external positioning mobile telecommunications operator, to obtain location information of a mobile terminal user, supported by the GIS platform, a value-added service to provide the corresponding service for the user.
- Q: What is the price of the car mounted GPS locator
- Cost structure:1, GPS locator hardware costs about 300 investment;2, mobile phone traffic card monthly package costs about 5 dollars a month;3, GPS positioning platform cost three six five things first free 60 per
- Q: Method of use of GPS
- There are a lot of applications in life, like our usual car navigation, traffic recorder...... Are built-in GPS module for positioning navigation. GPS is positioning and navigation, as long as you need to locate the device and navigation functions can be built or external GPS module. Shenzhen Tiangong GPS module
