Q: Ask you where to buy the forum of the friends of the shop where to buy GPS locator good? To genuine, to a place?: Xiamen will be the first in the industry to develop a company in the cave, tunnel, underground patent positioning technology, regardless of the vehicle in what position, can achieve positioning and tracking. GPS anti-theft device product features: 1, SMS control: the owner can use the phone to complete the positioning, tracking, query state, query parameters, set parameters, almost all of the operations. The location description is sent to the owner in the form of Chinese text messages. 2, vibration alarm: under the state of security, the vehicle was abnormal vibration, will trigger the alarm. Send alarm information to the owner.

Q: I bought a real carpenter car GPS locator, and then I clearly insert the boot how to display is not enabled? Which God knows?: You look at the following is not the case, in accordance with this solution(1) to see if the card is mobile, Unicom compatible 2G network and open the flow package, you can not use millet card, virtual, Ali, 0 monthly card.(2) insert the card and then boot. Look at the card is not pressed in, the direction of the card is the gap in the direction of the chip down by pressing inside

Q: FiveFor example, tied in the hands of children, the elderly, the family can see the child through the mobile device, the elderly where they are now. Lost can also find back? But the vast majority of the need for SIM cards, there is no need for a similar SIM card locator? Can you recommend a brand?: There is no need to insert the SIM card GPS locator? FiveFor example, tied in the hands of children, the elderly, the family can see the child through the mobile device, the elderly where they are now. Lost can also find back? But the vast majority of the need for SIM cards, there is no need for a similar SIM card locator? Can you recommend a brand?Kissno07Recommended 2016-02-05 06:57:58 best answerPositioning principle:Positioning satellite signal to obtain latitude and longitude,And then upload the latitude and longitude to the server through the network,The server analyzes the specific location,People search the location of the locator by phone or computer;If there is no SIM card, then the latitude and longitude of the device can not be issued, we can not query the location of the device, so there is no SIM card GPS locator does not exist;If applied to navigation, you do not need to upload latitude and longitude information, direct calculation of latitude and longitude in the local navigation and then you can, do not need a SIM card.

Q: Taobao to buy, the brand is the star GT02S, I was full of an electric car, opened only once, put a few days at home did not open, the results of last night to open the door even halfway out of the electricity, and hurt me back to the cart -!: Not great, you should be estimated about 7 days without riding the electric car, you like this, if the car is put in the home, and was afraid of being stolen, you can set the background data upload frequency, the time is a little longer, try not to easily turn off the equipment installed to positioning and theft the;

Q: Can not be installed on the dog like a car on the location of the GPS Dongdong?: Chip to the dog ah, we hit the houseCan not find lost can not know.

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.

Q: What kind of GPS locator meets the needs of the car loan industry?: Wired and wireless combined with the best, wired real-time positioning to understand the trend of the car, looking for a wireless car is the key. Rice gm06 and gm08b together, the only choice

Q: What is the role of GPS: GPS application scopeMainly for ships, automobiles, aircraft and other moving objects for positioning and navigation:1 ocean navigation and incoming water diversion2 aircraft route guidance and approach landing3 vehicle autonomous navigation4 ground vehicle tracking and urban intelligent traffic management5 emergency rescue6 people travel and adventure7 personal communication terminal (with mobile phones, PDA, electronic map integration)1 power, telecommunications, telecommunications and other network time synchronization2 accurate timing of admission3 accurate frequency of admission1 geodetic measurements of various levels2 Road and various line lofting3 underwater topographic survey4 crustal deformation measurement, dam and large building deformation monitoring5.GIS application6 construction machinery (tyre crane, bulldozer, etc.) control7 precision agriculture

Q: What are the benefits of using the vehicle GPS locator: there is a car needs the financial industry, leasing industry to protect their property safety, is it, in the final analysis, the main purpose is to locate and manage. There are questions can be more understanding, look at the map to find me

Q: Is the relay of the GPS locator installed in the front or rear of the high voltage package?: You put the relay directly connected to the battery, the relay into the 12V power on the line
