Q:Car GPS positioning system what line

Standard GPS locator only 4 lines need to be connected, so the first car in the following bold font to find a few lines. GPS red line, car locator DC12/24v GPS electric car, locator black line anode ground wire / GPS white line, car locator (ACC/ key line detection engine switch state, will take) GPS locator yellow line, car oil / oil line route (which can be accessed by)

Q:What does GPS mean

GPS prospectBecause of all-weather, high precision and automatic measurement of the characteristics of the GPS technology has, as an advanced measurement tools and new productivity, has been integrated into the national economic construction, national defense construction and social development in various applications.With the rapid development of the global economy and the end of the cold war, the U.S. government announced during 2000 to 2006, under the premise of ensuring national security is not threatened, cancel the SA policy, GPS civil signal precision is improved in the global scope, single point positioning by use of C/A code accuracy increased from 100 m to 20 m, application this will further promote GPS technology, improve productivity, work efficiency and scientific level and people's quality of life, stimulate the growth of the GPS market. According to experts predict that in the United States, just the car GPS navigation system, after 2000 the market will reach $3 billion, while in China, the car navigation market will reach 5 billion yuan. Visible, GPS technology market prospects are very impressive.

Q:Stop the car after the oil off the power, GPS locator can be loaded in what position?

In the idle state, unplug the oil film should be immediately pound insurance vehicle flameout, then cut open the corresponding oil supply line will relay 2 pounds, green line series, white line and red line equipment connection and butt joint of yellow line and yellow line locator; after the installation is complete, in the idle condition, the relay the yellow line ground, if the vehicle can immediately turn off line is installed correctly, if not, it may be wrong or cut oil pound line together with the white line without the red line.

Q: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.

Q:How to find whether the car was installed GPS positioning

Now the GPS are generally connected to the battery; in the cab or under the dashboard has a small black box, the line picked on the line. If that kind of power supply can be easily sucked that kind of have to go to the garage.How to install:1, the car battery power is provided by battery cathode is received online, so you find a key in the closed door case, find a common line, the anode of the battery is directly connected to the vehicle frame and the ground can be so negative directly. GPS needs a power supply. Then the antenna will be fine.2, in general, will be positioned in the middle of the tracker to control the good point. Car GPS positioning tracker is divided into three types: wiring (as well as different functions, more functions, a little bit more complex wiring), OBD interface, with strong magnetic. The OBD interface is more convenient installation, like micro company T5S, just plug in the steering wheel below the OBD port can be. With strong magnetic, that is, there is a locator magnet, as long as the car in the adsorption of iron, can be positioned. Wiring a little trouble spots, to take the line, according to different functions to set an gt02a car like rice only positioning function, only the positive and negative two lines, pick up convenient; like the ACC line, relay line etc..The positioner need to insert a CDMA card, connected to the GPS antenna and CDMA antenna signal signal, power supply is connected with the car, can work, if you need to power off the oil, can also be the host power off the oil control line, you can achieve these two functions, the method of installing GPSONE car the following will be the main power line tracker GPS host and auto connect phone card inserted on the login platform ready to start positioning.

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;External antenna: separate equipment and antenna device consists of a host, a signal line, power line, this kind of equipment for external signal line, can be placed closer to the sky outside the range, so the signal and stability will be much better, the accuracy will be better.

Q:What is the GPS locator wireless network

GPS positioning system is the use of satellite positioning. Data is the use of mobile phone SIM data traffic report.

Q:GPS locator if the thief was removed how to do

So how to prevent the GPS locator was removed to prevent GPS locator was removed and what are the effective methods?1, can be used to prevent the demolition of GPS locator, when the equipment is damaged, increase the difficulty of removal.2, the use of standby power supply GPS locator, when the external power supply is damaged, can still be short-term positioning, and issued a warning message.3, as far as possible hidden installation. Equipment installed in the car is not easy to be found.4, after the removal of the track playback function can be used to find the law of motion of people or vehicles.5, in the conditions allow, you can install two GPS locator, the thief after the removal of a lightly, often do not go looking for another.

Q:Do not return the data through the operator GPRS is simply relying on the GPS locator to transfer data, if there are many GPS locator, how to know that locator is what you want,For example, A has a GPS locator body, A home must have a receiving device. In addition B had a B locator, the home also has a receiving device, receiving device is how to know B A's or B's body. A similar pair, do you understand

It is only in a certain range (such as 10km) using the short distance wireless communication, which does not require the support of GPRS, like a battlefield combat squad is much too far away? Only with high power directional antenna or satellite antenna.

Q:Which satellite positioning system is used on Baidu maps?

Baidu maps do not have their own satellite positioning system. GPS satellite positioning system.
