Q: What does GPS mean: GPS principle24 GPS satellites orbiting the earth at an altitude of about 12 thousand kilometers from the ground, making it possible to observe more than 4 satellites at any point on the ground at any time, at any point in the.That due to the precise position of the satellite in the GPS observations, we can get the satellite to the receiver distance, the distance formula of three-dimensional coordinates, using 3 satellites, can be composed of 3 equations, solved observation point (X, Y, Z). Considering the error between the satellite clock and receiver clock, in fact there are 4 unknowns, X, Y, Z and clock, which requires the introduction of fourth satellites, the formation of 4 equations to solve, in order to get the observation points of latitude and longitude and elevation.In fact, the receiver can often be locked more than 4 satellites, then the receiver according to the distribution of the satellite constellation is divided into several groups, each group had 4 teeth, and then through the algorithm selected a set of minimum error for positioning, so as to improve the accuracy of.Due to the orbit of the satellite, the satellite clock error, the impact of the atmospheric troposphere and ionosphere on the signal, as well as the artificial SA protection policy, the positioning accuracy of civil GPS is only 100 meters. In order to improve the positioning accuracy, commonly used differential GPS (DGPS) technology, the establishment of base station (differential Taiwan) were observed in GPS, using the known exact coordinates of the base station, compared with the observed values, so that a number of amendments, and released. After receiving the correction, the receiver compares with the observed values, eliminates most of the errors, and obtains a more accurate position. The experimental results show that the positioning accuracy can be increased to 5 meters by using differential GPS.

Q: How to locate a car with a cell phone: The third step: wiringAfter installed card, back to the first step. Installation of a variety of color line order to ensure that the connector is not loose, not water. Please use the connection process auto circuit wiring method standard, do not do things carelessly. Wiring processing is not good, on the one hand, it is easy to make the GPS locator power fail to work, there are some short circuit fire safety risks.

Q: At present, the global positioning system (GPS), vehicle positioning accuracy can be increased to less than 3 meters, if so, what is the theoretical basis? If not, what is the reason?: We use the accuracy of less than 15 meters, the Americans themselves can be very highThe use of GPS positioning, will be affected by a variety of factors. The factors affecting the accuracy of GPS positioning with GPS satellite can be divided into the following four categories:(1) SA from the U.S. government interests, by reducing the precision of broadcast ephemeris (Technology), adding high frequency jitter in GPS reference signal (Technology) and other methods, reduce the ordinary users using GPS navigation and positioning accuracy.(2) the satellite ephemeris error in GPS positioning, calculation of satellite orbit parameters at a time the GPS satellite position required is provided by various types of [7] ephemeris, but irrespective of the type of ephemeris, the calculated satellite location will be its true position difference, this is the so-called ephemeris error.(3) the satellite clock error of satellite clock error is the error between the installation on the GPS satellite atomic clock clock with GPS standard time.(4) satellite signal transmitting antenna phase center deviation satellite signal transmitting antenna phase center deviation is the difference between the nominal phase center and the true phase center of the signal transmitting antenna on the GPS satellite.

Q: Taobao to buy, the brand is the star GT02S, I was full of an electric car, opened only once, put a few days at home did not open, the results of last night to open the door even halfway out of the electricity, and hurt me back to the cart -!: Hello, not much, because it has a very low quiescent current!Yeah, it's a lot of money, don't take too long

Q: Car GPS locator which is good: So, don't listen to other people say bad, oneself choose.

Q: Principle and application of GPS: The basic principle of GPS positioningGPS is the use of satellite positioning basic triangle positioning principle, GPS receiving device to transmit radio signals in time measurement to measure the distance, the distance to determine the position of the satellite in space, this is a kind of high precision positioning and orbit observation way. That satellite in 11000 miles high, measuring the distance from us, first to 11000 miles radius, this satellite drew a circle as the center, and the location is in a sphere.Application of GPS in personal positioningThe first voice MMS GPS locator (what is GPS) - sunstudy wholly owned technology MMS GPS locator for the column, it built the map data, without the background support, combined with the GPS global positioning system, GSM communication technology, embedded technology, GIS technology, voice broadcast GIS search engine, image processing and image transmission technology, direct response Chinese terminal address, MMS, voice broadcast or location

Q: QQ inexplicably with GPS positioning how to cancel: You want to cancel the GPS function there are two ways,A: in the phone settings, find the GPS positioning function, close, the general mobile phone drop-down menu button to close the GPS function.Two: open the QQ, the menu settings to find the GPS function off, but so that other software can also use the GPS function, but closed the QQThank you

Q: European GPS locator customer service phone: My device IMEI number forgot? Can you help me find it

Q: The difference between the built-in antenna and external antenna of GPS positioning equipment: Built in antenna, is a device and an antenna, the antenna in the device, the appearance of such equipment will generally be relatively small, but how much will affect the signal reception;

Q: After the phone off the GPS service, but also be tracked?: If the mobile phone when the hand closed the GPS service, can be traced to? The answer is yes, but also needs some conditions.The principle is: one of the GPS mobile phone only realize the function of positioning technology, but also through the communication base station, Wi-Fi hotspot to mobile phone positioning. The localization technique is used most in all kinds of mobile phone positioning software is GPS positioning technology and base station positioning.
