GPS does not have a signal strength statement, but you can get an approximate accuracy value by judging the error range
I don’t understand ocj-c
html5 has geolocation API, see: http://www.w3school.com.cn/html5/html_5_geolocation.asp
The accuracy attribute of the coordinates object is the position accuracy
update1:
According to my previous experiments, the accuracy of using wifi+3G signal is 600~1800 meters
If you use GPS, you need to check whether the GPS has been positioned. Generally, if the accuracy value is greater than 25 meters, the navigation software will display that the GPS has not been positioned
Positioned will be displayed after 5 to 20 years
