Recently, we have the opportunity to transplant a GPS device to our product. It is very easy for the GPS module to transplant itself. A friend who has developed GPS for wince or PC must be clear about it. He just reads the standard GPS data from the serial port, parses the data, and the application obtains the longitud

[Reprinted] Implementation ideas: 1. Use GPS to collect the signals from the satellites in the sky, and then transmit the data to the PDA through Bluetooth (of course other methods can also be used. 2. Run gpsgate on the PDA, accept data from GPS, and forward the data to the Internet through UDP sender to your home computer. 3. The data forwarded by gpsgate is connected to

GPS Information Processing System Based on Single Chip Microcomputer Global PositioningSystem, GPS) is a non-autonomous navigation and positioning System developed by the United States in 1970s and fully established in 1994 based on satellite signals With the ability to provide high-precision 3D location, 3D speed and time information around the world, around the clock, and in real t

Research and development of GPS products is the choice of GPS module or chip scheme. The market above the GPS program, how to choose it. I have been in contact with GPS design for several years, and now the experience of GPS project selection summarized as follows: First, t

Introduction to GPS GPS is short for the English Global Positioning System (GPS. GPS was jointly developed by the US Army of land, sea, and air in 1970s. A new generation of spatial satellite navigation and positioning systems. Its main purpose is to provide real-time, around-the-clock, and global navigation services f

Chinese is called: Global satellite navigation system, global navigation satellite system.GNSS refers to all satellite navigation systems, including global, regional and enhanced, such as the U.S. GPS, Russian GLONASS, European Galileo, China's Beidou satellite navigation system, and related enhancement systems, such as the United States of WAAS (wide area enhancement syst

I used to find information that I could not find. Using appropriate initialization statements and control commands can greatly speed up search and reduce power consumption. It is used when designing low-power instruments. Currently, the design of the instrument is measured on foot, and the movement speed is very slow. Therefore, the update time is changed from 1 second to 10 seconds, which can reduce power consumption. After all, battery devices can be used, the power supply is still very tight

The first purchase of the car navigation system has a GPS signal reception function, you can receive GPS latitude and longitude signal, and then the navigation terminal installed in the navigation map can be very detailed to display the specific latitude and longitude coordinates and figure information. The navigation terminal receives the free latitude and longitude signal of the satellite 24-hour uninterr

Recently, a customer asked for a GPS Vehicle Monitoring System to display the location of a car on an electronic map in real time. He had never been in touch with it before and learned from the beginning. First, you must understand the GPS signal format and transmission method. Otherwise, how can you use a program to get the coordinates of the car. Internet g, GPS
