Q:Would like to give a child with a primary school, children carry, I do not know whether it will bring bad results to the child. Please help us to understand this analysis.: You're talking about GPS+GSM or CDMA's personal tracker.The core component is divided into two parts, one is the GPS part, this part of the radiation is very small, almost negligible, because it is pure receiving equipment, like radio.There is a part of the location of the sending part, similar to a short message module, this part of the radiation and the phone almost. Especially in areas where the signal is relatively weak, the transmitter will automatically increase the transmit power.

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:Samsung smart phone has no positioning system: Recommendation:1 use the GPS in an open space and position it as far as possible in a static state (about 5 minutes), and then try to use it in a state of motion.2 if the phone supports A-GPS function, it is recommended to open the function. Method: setting - Positioning Services - using wireless networks - hook (open A-GPS will consume traffic).3 try to replace other location.4 if it is invalid, please backup the phone data (phone, SMS, multimedia information, etc.) to restore the phone factory settings to try again.If the problem still exists, it is recommended to carry the purchase invoice, warranty card and mobile phone to the local Samsung service center, by the engineer to solve.

Q:Does the car have its own positioning system?: Such as high-grade cars are some, ordinary cars to buy their own

Q:At present, the accuracy of civil GPS in the end is how much?: The navigation accuracy of GPS type belongs to the single point positioning accuracy, probably between 3~15 meters; high precision measurement of GPS generally refers to the accuracy of RTK, to 10 cm; the accuracy of WGS84 coordinates accuracy; usually see vehicle navigation or mobile phone navigation precision is high when there is a map of the correct.

Q:Principle and application of GPS: Three, the application of GPS in car navigation and traffic managementThree dimensional navigation is the primary function of GPS, aircraft, ships, ground vehicles and pedestrians can use GPS navigation navigation. Vehicle navigation system is a new technology developed on the basis of global positioning system GPS. The vehicle navigation system is composed of GPS navigation, autonomous navigation, microprocessor, vehicle speed sensor, gyro sensor, CD-ROM driver, LCD display. GPS navigation system and electronic map, radio communication network, computer vehicle management information system can be achieved, such as vehicle tracking and traffic management and many other functions.GPS positioning system is not only used for navigation and positioning of missile, spacecraft, is widely used in automobile, ship, aircraft navigation, public security, banking, medical, fire protection, the establishment of monitoring alarm and rescue system with it, the establishment of a modern enterprise logistics management system with it, agriculture, forestry, environmental protection, resource investigation, physical exploration, telecom all cannot do without navigation, especially with the integration of micro satellite navigation receiver, a personal information terminal of various financial communication, computer and GPS in one of the satellite navigation technology applied to the public from professional application, become after communications and Internet IT third new growth points. GPS as the representative of the satellite navigation and positioning industry is attracting more and more attention.

Q:How to shield the signal of GPS vehicle locator: This year, people really strange good features do not have to block up

Q:What is the meaning of the GPS locator LBS?: It includes two meanings: the first is to determine the location of the mobile device or user; secondly, to provide various information services related to the location.
