　　The GPS module has three parameters: cold start, hot start, and warm start (the current technology has basically made the parameters of the cold start and warm start modes very close, thus gradually canceling the warm start). If the GPS module is powered on for the first time or powered on after moving more than 500 kilometers, the module needs to recalculate the ephemeris data, Under normal circumstances, the GPS module can locate normally in just over 30 seconds (which is called a cold start). The S-87 has a built-in button battery that can store ephemeris data inside the module. When the module works next time, it can quickly locate. Generally, a new positioning can be achieved in just 1-3 seconds like the S-87, which is called a hot start. If the module loses power for more than 4 hours, the internal RTC does not have real-time power supply, So starting up again is also equivalent to a cold start.
