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:Mobile phone can be tracked after the closure of the GPS?
When you open the phone GPS service, and through the wireless network to locate the GPS positioning information, the phone can be traced. If the phone closes the GPS service, can it be traced?

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:GPS and tracking locator are two different things,
GPS tracking is to be used together with the software platform, you need a traffic card (cards), GPS tracker receives the position information sent to the car after the satellite communication module through GPS tracking which sends the location information to the software platform, which is through your traffic card, the the process will have a certain flow of costs;
