About the GPS Tracker drift

Earliest ,GPS tracker because accept ability is weak, always broken, to be used for navigation, especially in the city to travel caused many inconvenience. Later development some civilian GPS chip, the signals are not strong in the GPS signal is income, thus causing the drift phenomenon.

Xtrac technology of GPS signal will be gone with the wind are most frequently happened problems (Gao Gan degrees of GPS is mostly use Xtrac technology, GM - 270 - u), because it is the use of computing to locate the weak signal amplification, and the satellite signal all the time change, so the GPS continuous operation to correct error, when the received signal before and after very different, you will see the drift phenomenon. Navigation software is only receive signals from the GPS, the positioning signal appeared on the screen, so it has nothing to do with the signal drift, is purely a GPS receiver position error.

Moreover, the error of the GPS who number is 5 ~ 25 meters, lock road map software programming is about, of course, but the receiver factor is larger.

Last used GPS coordinates system and the electronic map coordinates system (rare) are the same?

GPS cold startup, warm startup, warm start

GPS trackers  boot is divided into cold start and warm start and hot start:

Cold start, the following several ways on cold start. Used for the first time; Ephemeris information loss, as a result of its battery runs out; Shutdown condition. Move the receiver more than 1000 km distance.

1. The shape material work

This method is the simplest and most intuitive method, generally private car GPS terminal equipment appearance is square shape, all will have ling side appear user when buying can to hand to touch the ling side did see whether smooth hand feel, piracy GPS in order to save time and the price won't spend too much time to get these, GPS shell on the radiation intensity is crucial, users also want to pay attention to distinguish the singing of these key components and materials.

2. See the data return rate.

This refers to: from the speed of the car is returned to the monitoring center which is affected even sex and accuracy of data, common rebates time for 30 seconds or so commonly, such as the all a 70 degree bend, back when you turn into a point, leave curves you use for 30 seconds, leave and return to a point, when I was in the middle that's 30 seconds away he said can only in a straight line, because in the center of the monitor that is equivalent to 30 seconds of his blind spots. You can look at the log in the merchant's platform.

3. Look at a map is updated in a timely manner

Navigation electronic map is a core technology in GPS devices, is of vital importance in the navigation is generally are equipped with the original authorized brand GPS map, and the less known and inferior brand usually adopt cracking map to deceive consumers, so the owner will be in doubt whether the map is good, to judge the stand or fall of navigation electronic map is the most intuitive way to know how much is the updated date then.

Warm prompt: above is for the caboose star will teach you how to choose and GPS car tracker related knowledge introduction, here is to remind the user more than three points is the most intuitive to judge out there you can also from the GPS system, chip, antenna, the processor, memory, screen, buttons, speakers and so on to look at it.

To achieve this purpose, the position of the satellite can record according to the spaceborne clock time found in the satellite ephemeris. While the user is the distance to the satellite transmitted to the user experiences by recording the satellite's signal, multiplied by the speed of light to get it again (because of the atmosphere, the ionosphere disturbance, GPS tracker, this distance is not the real distance between user and satellite, but the pseudorange (PR) : when GPS satellite work normally, will continue to use the binary 1 s and 0 s element consisting of pseudo-random code (pn code) launch navigation message.

GPS vehicle tracker system using the pseudo code of A total of two kinds, respectively is civil C/A code and P (Y) code for the military. C/A code frequency 1.023 MHz, repeat cycle is A millisecond, code spacing of 1 millisecond, equivalent to 300 m; P code frequency 10.23 MHz and 266.4 days, repeat cycle code spacing 0.1 microseconds, equivalent to 30 m. And Y code is on the basis of P code, secrecy performance is better. Navigation message includes satellite ephemeris, working conditions, and clock correction, ionospheric delay correction, correction of atmospheric refraction and other information. It came from a satellite signal demodulation to 50 b/s on the carrier frequency modulation launch. Navigation message contains five child frame each main frame of the frame length 6 s. The first three frames each ten word; Repeat every 30 seconds, updated every hour
