Test the u-box GPS professional testing software u-center map function
Some time ago, I mailed a GPS module from the Internet and recently played GPS positioning. I found a Go-GPS module that can call GoogleEarth, and the coordinates are displayed in real time, but I have not completed the transmission part, I can onl
Mobile manages the ing of GPS ports, so GPS supports multipleProgramRun simultaneously. During GPS development, we can read NMEA metadata from the GPS hardware and parse it according to the protocol. Of course, you can also use the existing open-source class libraries. I have two open-source class libraries: gpsreader
Pdop: Position dilution of precision. It is translated as "precision intensity" and is usually translated as "relative error ". The specific meaning is: because the quality of the observed results is related to the geometric shape between the measured man-made satellite and the receiver, therefore, calculating the error volume caused by the above is called the strength of accuracy. The better the satellite distribution in the sky, the higher the positioning accuracy (smaller the value ).Pdop is
This is the case. I bought a Sony as100v motion camera to record my own life and be interested in video editing. When the company arrived, he took a picture on his way home. He rushed home to connect to the computer and wanted to see GPS data. He found that Sony had a private variety. So he found related information on the Internet, I want to convert it into Google Earth's kml, Chinese search, and English search. I couldn't find it until three o'clo

Android GPS obtains the coordinates of the current longitude and latitude
In the APP, there may be a need to upload the coordinates of the current location to the server. Today, I provide three ways to obtain the coordinates of the longitude and latitude. The first is implemented through the Android API, the second is implemented through the Baidu map API, and the third is implemented through the map world API.
The first method (Android API implementa

When the Linux Startup configuration file grub is started, a file named grub is located in/boot/grub. conf configuration file. If the configuration file cannot be found, the command line mode is directly entered without entering the menu mode.

started in inetd mode, define the port used in inetd. conf.
Root permission is required to use port 80 in Unix. for security reasons, some administrators believe that the httpd server cannot have security vulnerabilities. Therefore, they prefer to use the permissions of common users to start the server, in this way, port 80 and other ports smaller than 1024 cannot be used, but Port greater than 1024 must be used to start httpd. generally, port 8000
