????GPS boot positioning is divided into three types: cold start, warm start and hot start:

????Cold start: The following conditions are all cold start. When using it for the first time; when the ephemeris information is lost due to the exhaustion of the battery; when the receiver is turned off, move the receiver for a distance of more than 1000 kilometers.

????Warm Start: Start when the last positioning time is more than two hours.

????Hot Start: Start when the time from the last positioning is less than two hours.
