Q:GPS positioning system accuracy?
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:Car GPS locator is not a battery
Travel GPS solution:Car locator with battery GPS is divided into two kinds: one is the connection type, is to wiring to the car with a car battery, and GPS equipment itself with the battery, if the car battery power, the GPS device itself can also adhere to the localization of 3-5 days.

There are several possible:First: signal interference, GPS antenna near the iron or magnetic field.Second: the shelter, tall buildings, mountains and basements will cover the satellite signal.Third: time set, time is not allowed or return interval is too long error.My answer to your help please take ah!
Q:How to locate a car with a cell phone
Automobile GPS installation method:Step 1: find the lineInventory required positioning terminal parts and wiring tools are complete.GPS locator standard in only 4 lines to pick up, so the first to find out a few lines in the car following bold font.GPS locator, red line constant electric car DC12/24vGPS locator black line, car / ground wire electrodeGPS white line, locator car line (ACC/ key switch state detection engine, will take)GPS locator, yellow line automobile oil / oil line route (which can be accessed by)The second step: install SIM cardSIM card in GPS positioning system plays an important role, that is to say a GPS locator for the acquisition of latitude and longitude data acquisition terminal, to the latitude and longitude data, through the SIM card of the GSM network in the form of GPRS to transmit data to the specified background, the final form of positioning and monitoring system.Note: please make sure that the GPS positioning terminal SIM card inserted in the case of electricity, otherwise easy to burn card.
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.
