 Q: What is the GPS single positioning?

A: Because V8 is a personal portable GPS communicator , is limited by the battery life, in order to save electricity, immediately enter a dormant state after each GPS positioning, so V8S every location is actually cold start.
If shorten the V8 positioning interval to 1 minute, in the motion state for a while, would be much better, but this can only maintain the standby time about 6 hours.

A: Yes, it’s mean the GPS don’t work now

1. Because the GPS is very power-hungry, so V8 is designed to position every 10 minutes, and immediately dormancy after positioning so as to save electricity,  to ensure the standby 50 hours.
