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 Google
Earth, and the coordinates are displayed in real time, but I have not completed the transmission part, I can only put the GPS module on the serial port, the antenna to the window account positioning.

I used the u-center software debugging module of the u-box company a few days ago and accidentally found that there was a map function, but there was no suitable map at hand, so I did not study it in depth.

I saw the notice on the school website today and accidentally saw a good map. It is still relatively new, and the new buildings are also marked. It is better to use it to try the map function of the u-center. After several attempts, the system finally successfully located the site after multiple failures. Now, the setting method is recorded here for interested friends to check.

U-center supports most image format maps (bmp, gif, and jpg). After opening the map for the first time, the system prompts that there are no coordinates. You must confirm the coordinates of the longitude and latitude of the three points before using the map. The longitude and latitude coordinates of the geographical location can be obtained through Google
Earth. It is best to select a corner of a building with characteristics. I use Google
The landmark function of earth to accurately determine the coordinates of a building's corners. As shown in. Locate the longitude and latitude coordinates of the three locations and record them on the paper for backup.

Then you can open the u
The center imports the map to determine the coordinates. Generally, when you create a chart for the first time, the system prompts that no calibration file exists in the dialog box. You must select three known points on the map and enter the coordinates and click OK, then select the location you just found and enter the longitude and latitude coordinates (in the form of recommended usage, minute, and second, no need to convert it again ). As shown in.

After entering the coordinates of the three known locations, you can locate them. Of course, you must ensure that your GPS module is connected to the serial port and works properly. You have tracked the satellite and started positioning. Is the positioning effect. Erase coordinates, saving people from flying me with missiles.

GoGPS + Google earth navigation and positioning map.

Conclusion:

Both the u center and GoGPS + Google earth can be easily positioned (the precision between several meters and dozens of meters will drift with time), while the u
Center allows you to import your own maps for positioning, making it more flexible and entertaining. Of course, both of them require PC support, so they cannot go outdoors and use the GPS function, while GoGPS + Google
Earth also needs to download maps from the Network (some people on the Internet also want to download the local map in advance and then break the network to play, but unfortunately my hard disk is too small to match that condition ).

Try to learn embedded systems. If you have time, make a usable navigation.
