Q:There is no device can detect the location of the GPS locator
An external power supply GPS locator must be connected to the vehicle power supply, can work 24 hours, the general criminals want to use this product to track other vehicles, it is impossible. Because the car must be connected with the power supply, the difference between the general plug-in locator. Therefore, the use of external power supply is not recommended. rn
Q:How to effectively avoid accidental loss of the elderly? If the use of GPS positioning products which brand is good?
360 is designed for children. Keys are too small, the old man is not convenient to use. Rather than buy a special for the elderly with GPS locator, such as sharp peaks RF-V16 what the wise.
Q:Where to buy car locator
Taobao has price is not expensive about three hundred because the GPS store locator is generally not sold after all is the corresponding special group of market.
Q:GPS positioning is how to get offline
2, locator no cell phone signal.Dial the phone number through the phone locator, if the prompt can not be connected, not in the service area, this is the case. As far as possible to stop the car in a better signal environment. The positioner mounting position not too closed, do not have the metal of the block, installed on the car to rely on. In the underground garage, tunnel, remote occlusion and other areas without cell phone signal, will lead to the locator off line
Q:GPS if you can not use the military code to crack the military GPS high-precision positioning?
1, since it is "secret" crack, even if the people's Liberation Army will tell you?2, this involves GPS channel coding problem (I just took a course last Saturday), and crack the password is completely different concepts of the two. You confuse this crack with the password. It is a very complicated process to encrypt the spread spectrum codes of military channels. I learned one semester is not fully understood... Is spreading code added scrambling encryption and interference technology etc.. And the channel cycle is at least a few days, to try to crack do not want to think.
Q:There is no need to insert the SIM card GPS locator?
At present, it is impossible to have such a product.After receiving the signal from the GPS satellite, the GPS locator obtains the latitude and longitude information through the software calculation. This information must be sent out to be received by other devices, so that people who need to know the location of the locator get this information. So in the current circumstances, the launch of information, but also with the help of the mobile phone network, there is no other public network can be used, so the phone's SIM card is essential.
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:How much does it cost to install a concealed GPS locator? Which brand is good
1, look at what you install, there are wiring and wiring, I would like to install my own for example
Q:How to locate the car car
First, buy a satellite on the Internet to install the car, you can use a mobile phone or computer to locate the car,
Q:Car GPS locator is not a battery
Hello, there is a battery connected to the original car power
