FAQ
- I heard that the function is the most complete, you can listen to it? Many function
- Since it is the most complete function, it must be able to monitor, I just looked at their website, you can also see
- How to find mobile phone GpS satellite positioning car
- Automobile GPS installation method:Step 1: find the lineInventory required positioning terminal parts and wiring tools are complete.GPS locator standard in only 4 lines to pick up, so the first to find out a few lines in the car following bold font.GPS locator, red line constant electric car DC12/24vGPS locator black line, car / ground wire electrodeGPS white line, locator car line (ACC/ key switch state detection engine, will take)GPS locator, yellow line automobile oil / oil line route (which can be accessed by)The second step: install SIM cardSIM card in GPS positioning system plays an important role, that is to say a GPS locator for the acquisition of latitude and longitude data acquisition terminal, to the latitude and longitude data, through the SIM card of the GSM network in the form of GPRS to transmit data to the specified background, the final form of positioning and monitoring system.Note: please make sure that the GPS positioning terminal SIM card inserted in the case of electricity, otherwise easy to burn card.
- Is the GPS positioning system based on electromagnetic waves?GPS system depends on electromagnetic wave location. Is this the right or wrong?
- GPS global satellite positioning system consists of three parts: the space part - GPS constellation; ground control part - ground monitoring system; user equipment Part - GPS signal receiver
- Car GPS locator buy what brand good
- GPS locator has a lot of brands, each brand positioning is not the same;Some manufacturers are part of the development of vehicle locator for a long time, as well as the main research and development of personal use of the GPS locator, there is a small pet locator, etc.;
- GPS locator useful in the basement?
- There is no effect, because the tall buildings and hidden rooms, basements will block the satellite, satellite information lost.GPS locator is built-in GPS terminal module and a mobile communication module, GPS module for positioning data obtained at Internet on a server through the mobile communication module, which can realize the query terminal location on a computer or mobile phone.Principle: the spatial distribution of the GPS is composed of 24 GPS working satellites, these GPS working satellites together constitute the GPS satellite constellation, of which 21 are available for navigation of the satellite, the 3 for the active backup satellites. The 24 satellites are distributed around the earth in 6 orbits with an angle of 55 degrees. The cycle of the satellite is about 12. Each GPS working satellite sends out a signal for navigation and positioning. GPS users are using these signals to work.
- Do not return the data through the operator GPRS is simply relying on the GPS locator to transfer data, if there are many GPS locator, how to know that locator is what you want,For example, A has a GPS locator body, A home must have a receiving device. In addition B had a B locator, the home also has a receiving device, receiving device is how to know B A's or B's body. A similar pair, do you understand
- It is only in a certain range (such as 10km) using the short distance wireless communication, which does not require the support of GPRS, like a battlefield combat squad is much too far away? Only with high power directional antenna or satellite antenna.
- 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.
- Chengdu GPS locator installed there
- 3, cross-border alarm: under the state of defense, the vehicle moves beyond the set range, will trigger the alarm. Alarm information automatically sent to the monitoring center and the owner of the phone.4, online search car: positioning, monitoring, historical trajectory query, marking locations and other operations, providing the latest electronic maps, GOOGLE maps, three-dimensional satellite map.5, web alarm: overspeed alarm, regional alarm, web pop-up alarm tips.6, data statistics: speeding statistics, mileage statistics, speed statistics, alarm statistics.7, cut off the oil: you can cut off the oil off the computer remote, so as to play the role of anti-theft
