Q:GPS locator in the ACC detection function is what mean
ACC detection means that the vehicle ignition switch detection, when the ACC display is open, that means the vehicle is the ignition state.
Q:Europe creates GPS locator plus traffic card and no traffic card what is the difference?
The addition of the flow of the card is to make it always send data to the network users more simple client, such as WeChat, so that users do not need professional software, you can get locator location information.
Q:GPS locator platform to show off how is going on
GPS locator platform display offline two cases:First, the GPS locator dropped (wiring) can not electrify.
Q:Micro GPS locator locator locator shows no data display
6 3.SIM card arrears, GPRS service expires or package changes.7 consultation SIM card operators (for example: Mobile, Unicom: 10086: 10010), card arrears, whether the opening of the Internet, Internet is in effect, whether packages change, if it is a mobile SIM card, to confirm whether the GPRS access point is cmnet.After the exclusion of the above 7 conditions, the device is normal on the line, the GPS positioning platform or software can display the current location information and other related data!Hope to help you.
Q:Method of use of GPS
There are a lot of applications in life, like our usual car navigation, traffic recorder...... Are built-in GPS module for positioning navigation. GPS is positioning and navigation, as long as you need to locate the device and navigation functions can be built or external GPS module. Shenzhen Tiangong GPS module
Q:How can we know that the car is not installed GPS positioning system?
More than and 10 of the 200 thousand does not come, only the installation, if there is no radio on the installation of GPS
Q:Is it necessary for the car to mount GPS
The above may not have a clear understanding of the meaning of the GPS positioning device, GPS positioning and GPS navigation is not the same device, GPS positioning is the computer can be clearly seen on the map of the vehicle's real-time location information.Vehicle installation of such equipment, you can sit next to the computer, you can achieve the monitoring of vehicles, more suitable for the management of their own vehicles, as well as personal vehicle theft.If your vehicle is relatively high, the security can be installed.
Q:UU vehicle GPS locator convenient?
1, private cars, rental cars installed GPS positioning system, you can better manage the use of vehicles and anti-theft.2, concrete vehicles installed GPS positioning system, can better monitor the amount of concrete and construction progress.
Q:What is the principle of automobile positioning system?
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.
Q:What's the difference between AGPS and GPS?
Whether it is GPS or A-GPS, are mainly to receive satellite navigation signal using GPS navigation chip equipment, and GPS chip receiving satellite navigation signals are free of charge, but the positioning time is very slow, because it will take a few minutes to wait for a satellite to locate the GPS module to the navigation on your device. A-GPS based on the receiving satellite navigation signal, but also through the network (GPRS) to get you the instant communication equipment operation base station information (signal base seat), you can easily find the instant seat, let the satellite fast positioning of your equipment. So the A-GPS than the GPS positioning time soon.
