Use GPS positioning a month 3 hours a day with less traffic
- First: GPS professional equipment, GPS satellite positioning is not the flow of traffic, but to return to the network background software, to achieve background monitoring.For example: set five seconds to return a message, then it is a point of five seconds, and then point to the point of the connection of the straight line, if you turn in the next five seconds is not calculated, so the more the greater the deviation.You can also set the return interval is small, the smaller the distance, the greater the flow? Is 24 hours a day positioning five seconds interval return of 5 yuan package / month of 30 megabytes of traffic is enough.Second: mobile phone GPS, GPS does not need to flow, but the positioning information to be displayed on the map, then see what software you use, because the map is updated in real time online map, map it cost flow, this is the charge flow map refresh, especially for mobile phone navigation software, it depends on how much you load pictures and routes, the number of different loading, the flow is different, you can open one hour traffic statistics look at how much traffic navigation will know.You can try the offline map, so you can avoid traffics
