It is not an exaggeration to say that as long as the use of navigation and positioning productsgps gnss module, basically all can use the GPS module. So, what is the use of GPS module in daily life? Here's a brief introduction to you.
As a senior positioning module research and development manufacturer, SKYLAB has been based on the market for more than ten years, developing a series of industrial-grade high-quality GNSS (GPS/BDS/GALILEO/GLONASS) navigation and positioning modules for the market of car, smart wear (watch, bracelet ......), drone, car recorder, security, measurement and mapping manufacturers. /GLONASS) navigation and positioning modules. About the use of GPS in daily life, in a word summary is: as long as the use of navigation and positioning products, the basic GPS module can be used. However, it should be especially noted that because the GPS module's signal is affected indoors, indoor positioning is not possible with the GPS module and requires wireless communication, such as Bluetooth/UWB-based indoor positioning solutions.
The use of GPS in daily life is positioning, navigation, history track and distance measurement.
Positioning: Positioning is actually well understood. By measuring the distance between the satellites at known locations and the GPS module, and then integrating the data from multiple satellites, the detailed location of the receiver can be known, and with the support of electronic map information, the location information of people/objects can be determined for mobile users.
Navigation: The process of moving from one place to another based on the location information provided by the GPS module.
History track: Taking the GPS module used for vehicle as an example, the GPS module will automatically record all the information such as the speed of the travel route over a period of time, providing the manager to analyze whether the driver's work route is reasonable.
Distance measurement: the starting point (default current position), the distance moved to the other point to be measured.
Receiving sensitivity is the minimum signal receiving power that the receiver can correctly take out the useful signal. good receiving sensitivity of GPS navigation module makes the wireless products have stronger ability to capture weak signals. In this way, as the transmission distance increases, the received signal becomes weaker, the high sensitivity wireless products can still receive data, maintain a stable connection and significantly improve the transmission distance.
Positioning time refers to how long the GPS device will automatically start to determine its position, generally in seconds. When this time is reached, the GPS device will send a signal to the GPS positioning satellite and start to determine its own position. And it includes the positioning time of initial start, cold start, and hot (warm) start. No matter it is car navigation or map navigation in cell phone, it is built on the basis of equipped GPS module, the shorter the positioning time, the test data is more likely to be approved by engineers. At present, the cold start time of GPS modules developed and produced by SKYLAB is 23s, the warm start time is 2~3s, and the hot start time is less than 1s.
Position accuracy refers to the degree of conformity between the coordinate values obtained from spatial points and their real coordinate values. High accuracy of positioning accuracy is the basis of GPS positioning module design. If the positioning accuracy does not achieve the functional effect, then the magnificent GPD module design will also make people dislike. Of course, different navigation environments should be considered first before other factors are considered.
Positioning accuracy can be examined under static and dynamic conditions, and the dynamic positioning effect is better than static positioning. the GPS module's nominal positioning parameters are measured under a completely open sky with excellent satellite signals. Therefore, it is difficult to achieve the nominal positioning time and positioning accuracy in the conventional test.
Power consumption is the loss of power, referring to the difference between the input power and output power of equipment, devices, etc. With the rapid development of computer technology and microelectronics technology, embedded systems application areas are becoming more and more extensive. Energy saving is the globalization craze, such as many chips in the computer used to use 5V power supply, now use 3.3V, 1.8V, and put forward the concept of green system. Many manufacturers pay much attention to the low power consumption of GPS modules. The low power consumption design of the circuit and system has always been an important factor for electronic engineers to consider when designing. The GPS modules developed and produced by SKYLAB have power consumption values of only a few tens of mA, all of which are low-power modules, and engineers can use them with confidence.
Remote sensing of the Earth's surface and atmosphere has been accomplished using GNSS signals that have been refracted, reflected, and scattered. It has shown that it is capable of sensing the cryosphere, ocean, terrestrial surfaces, and the atmosphere and ionosphere.
A software-defined radio implementation that has been designed and developed in accordance with GNSS standards is known as a GNSS software receiver. A reconfigurable computational platform, such as a microprocessor, graphic processor, digital signal processing element, or field programmable gate array, is used to accomplish this.
Today, an aircraft's basic on-board equipment includes a GNSS (Global Navigation Satellite System) sensor, which enables it to record numerous navigational parameters in real time, including position, speed, time, and rotation angle.
