GPS module used in 4G GPS locator

The GPS module is a GPS signal receiver, which can be connected to a computer or mobile phone with wireless Bluetooth or wired, and transfer the GPS signal it receives to the GPS software in the computer or mobile phone for processing. The GPS positioning module we often say is called the user part, which receives and demodulates the satellite's broadcast C/A code signals like a "radio". The GPS module does not broadcast signals and is passive positioning.

The key to the application of the GPS module is the formulation of the serial communication protocol, that is, the relevant input and output protocol format of the module. It mainly includes data types and information formats. The data types mainly include binary information and NMEA National Marine Electronics Association data information. These two types of information can communicate with the GPS receiver through the serial port.

The GPS module calculates the pseudo-distance with each satellite and uses the distance rendezvous method to obtain the four parameters of the receiver's longitude, latitude, altitude, and time correction. The characteristic is that the point speed is fast, but the error is large. The module for initial positioning requires at least 4 satellites to participate in the calculation, which is called 3D positioning. 3 satellites can achieve 2D positioning, but the accuracy is not good.

With the development of society and the emergence and growing of demand for personal positioning services, personal locators have begun to enter people’s daily lives. This kind of personal locator with GPS module can monitor the position of the wearer in real time and send the information. Therefore, it can be used for personal positioning, anti-lost of children and the elderly, and anti-theft of objects.

In the personal locator, the GPS module can determine the location of the carrier by receiving signals from multiple positioning satellites, and the orbit data and transmission time of these satellites. Because this kind of positioning device is usually small, it has certain requirements on the size of the GPS module. At the same time, such devices are generally powered by batteries, so the power consumption of the positioning module should not be too large to maintain the working time of the personal locator as much as possible.

With 15 years of manufacturing experience, Eelink Communication Technology Limited has mass-produced various GPS tracking equipment, including vehicle tracking equipment, cargo tracking equipment, wireless temperature monitoring equipment, asset tracking equipment, etc. With years of development and technology accumulation, Eelink has become the world's top GPS tracker manufacturer company.
