Q:What is the meaning of the GPS locator LBS?

To detect vehicle OBD GPS locator self-test function as the European Bidi car safety steward

Q:GPS satellite positioning card how to apply for network services?

You buy in the end is a locator or card. Locator inside is a GPS positioning chip plus a mobile phone card, the chip is used to locate the phone card used to transfer data. It's no use buying only one card.If you are buying a locator, manufacturers will give you a sign on platform (some software, there is a website), you enter a user name and password. You can see, or in the mobile phone on a client can view, to give you the manufacturers as the standard, if the manufacturer does not have to you, you will find manufacturers to be

Q:Expert advice, which GPS locator is better?

The team's words with a professional GPS positioning is better we specialize in the production of GPS positioning support oil detection function, track playback, real-time positioning and other functions

Q:What brand of car GPS positioning system is good?

I am a communications professional, but also like cars and fresh stuff, after a lot of comparison after the election of a loaded in the car, with more than half a year is still worth recommending.Now the vehicle GPS positioning a lot of products, such as the basic functions of the track to find the location of real-time alarm, and so many can be done, I chose this now, there are several factors that attract me.1, the appearance of exquisite production process is done to see a large, supporting the charger and other accessories, packaging are very elegant.2, the antenna is built-in, not only convenient for concealed installation, and the sensitivity is very high, I tried to put in the back of the box can also be normal positioning.3, for enterprise users, the embedded vehicle management system and GPS system can realize the linkage, the driver not every day and then reported to the mileage, the system automatically collect data and generate statistical reports, real vehicle management automation, the system functions very much, not one out.5, the new position of SMS reminders, sometimes vehicles entering the underground garage, no signal, positioning equipment generally only know the final position, you have to know the new position, have to continue to pay attention to the page, and they are just sending a query message, the system will automatically determine whether the final positioning time in time, if found not in real time position in the new position to the web pages at the same time, but also the mobile phone SMS alert monitor.6, hand in vehicle mode interchangeable, handheld mode as well as the call text messaging function, the equivalent of a mobile phone for the elderly, children custody.Many of the products are designed to fit the needs of the user, I think it is moving in the brain, coupled with a lot of customers are government agencies users, indicating that the company is also a considerable strength.

Q:What is a dual-mode GPS locator

Such as: while supporting the United States GPS navigation satellite signals, as well as Russia's GLONASS navigation satellite signal.

Q:How to build GPS (location tracker) service platform

The first to have a second positioning software, to the server, so that you can, recommend software ECTEL GPS positioning

Q:Hello, not much, because it has a very low quiescent current!

The second: binding some devices are bound to bind the phone number to listen to the sound. But to spend six yuan to open the display, the device can know who is calling, is bound to the number, it is connected, you can hear. This brand is the city walk this way.

Q:Mobile GPS positioning official certification 837706606 is true

Mobile GPS positioning itself is true. Said the positioning of others, it is not necessarily true, there are many people, many. But on the whole can grasp:

Q:My friend bought a car to install satellite positioning system I am interested in my friend explained that I would like to ask who knows the professional interpretation (product principle) who knows who

It can be seen that the role of the GPS navigation satellite system is to continuously transmit navigation messages. However, because the user receives the clock and satellite machine using a carrier clock may not always synchronized, so in addition to the 3D coordinates of X, y, Z users, but also the introduction of a t that is the time difference between the satellite and the receiver as unknown, and then use the 4 equation the 4 unknowns out. So if you want to know the location of the receiver, at least to receive the signal of 4 satellites.The GPS receiver may receive for accurate timing information to nanosecond time; for forecasting ephemeris in the next few months which the approximate location of the satellite; used to calculate the required positioning satellite coordinates of the broadcast ephemeris, the accuracy of several meters to tens of meters (each satellite is different at any time change) and GPS system information; such as satellite status.The GPS receiver can get the distance from the satellite to the receiver by the measurement of the code, because it contains the receiver satellite clock error and atmospheric propagation error, it is called the pseudo distance. The pseudo distance measured by the 0A code is called the pseudo distance of the UA code, the precision is about 20 meters, the pseudo distance measured by the P code is called the pseudo distance of the P code, and the precision is about 2 meters.
