The GPS module generally supports two modes: cold start and hot start (note: warm start is not discussed)
Generally, the cold start time is much longer than the hot start time. Taking the signal as an example, the hot start time of SirFIII is less than 15 seconds, and the cold start time is less than 42 seconds; In case of weak signal, it will take longer; The hot start conditions are as follows:
(1) The location information (longitude, latitude, height) before the last shutdown is known (so the next shutdown in the garage must be a cold start);
(2) The current time, calendar and ephemeris are known (real-time clock support and E666 support are required)
(3) The time from the last shutdown is less than 4 hours (if the time is too long, the ephemeris changes, that is, the previous satellite cannot see it)
