Since the advent of GPS self-positioning technology, it has been maturing and expanding its range of applications. In all relevant applications, it is inseparable from a special component which is the GPS module.
What is a GPS module
GPS module is GPS signal receiver is a signal receiver that can be connected to a computer or cell phone via wireless Bluetooth or wired GPS signal transmission to the computer or cell phone GPS processing software. We often say that the GPS positioning module is called the user part, just like the "radio" the same receive and demodulate satellite broadcasts C / A intermediate frequency of 1575.42MHz. GPS the module does not play the signal, belongs to the passive positioning.
The application of the GPS module is the key to the development of serial communication protocols, that is, the module of the relevant input and output protocol format. It mainly includes data type and information format, where the data type is mainly binary information and NMEA through the serial port and GPS receiver communication.
GPS The module obtains four parameters of the receiver by calculating the pseudo-distance to each satellite using the distance-crossing method: longitude, latitude, altitude, and the amount of time correction. It is characterized by a fast point location, but with a large error. Initial positioning module requires at least four satellites to participate in the calculation, known as 3 D three satellites can be positioned 2 D positioning, but the accuracy is poor.GPS through the serial communications port continuous output module NMEA receiver can choose the format positioning information and auxiliary information.
With the development of society and the emergence and growth of the demand for personal locator service, personal locator is beginning to enter people's daily life.Personal locator with GPS module can monitor the wearer's location in real time and send information. Therefore, it can be used for personal localization, children and elderly people to prevent loss and anti-theft of goods.
The GPS module in a personal locator can determine the geographic location of the carrier by receiving signals from multiple positioning satellites and the orbit data and transmission times of these satellites. Because such positioning devices are usually small in size, yes the size of the GPS module has certain requirements. At the same time, such devices are usually battery-powered, so the power consumption of the positioning module is not too large in order to maintain the operating time of the personal locator as long as possible.
GPS improves the ultra-high sensitivity of the module through cold-start technology TTFF This total solution can be used to design ultra-compact applications (time to first fix) and indoor positioning accuracy. Compared with the traditional than PCB with printed circuit boards, the cost of using this solution is very low, only a small amount of external BOM is required, and also able to greatly reduce the size of the package.
