All GPSs cannot receive satellites or signals indoors very weak. Only signals can be received outdoors. This is common sense.China
The method of searching the signal correctly is:
1. Fix the search signal, do not walk, because walking GPS is not good for positioning.
2. Open the machine to the navigation interface, click on the upper right corner of the navigation interface. The signal logo can be seen, you can see the number of satellite number diagrams, normal positioning, 5 navigation.<Our Xinghangtong GPS can receive 7-12 satellite navigation signals to stabilize, enough for you to use it.
3. Open the GPS on the right upper right side of the machine to receive the satellite signal module and the machine to form a 90 -degree angle to receive the signal.
4. The speed of receiving signal: involves two concepts
(1) The meaning of cold launch: It is the first time that the GPS search satellite is called cold start, usually slow.
Different GPS searches are different. Some GPS cold startup searches for satellite time is within 1 point, some are 1 point, about 1 to 2 minutes, and some are 2 points.
(2) The meaning of heat startup: After that after 2 hours, the heat start is the hot start. The hot start is the fastest.
Satellites are usually found in 1-2 seconds.2 hours-4 hours are warm start
About electronic dogs
At present, the function of electronic dogs in all GPS is the function of the navigation map, that is, the electronic dog map with an electronic dog in the machine."Da is a state forbidden to sell goods, and it is also forbidden to sell Taobao."About GPS electronic dog function is as follows:
1. That is, there is a speed measurement information point at the crossroads in the GPS map, and GPS will remind you of voice.
2. There is no speed measurement point in the map, it will not remind you.So you cant just rely on GPS to reverse speed measurement. There is a good way to help you solve: you can set the speed in the GPS yourself, and the speed of GPS will remind you of speed limit.
