(Autonomous Operation in Standard Sensitivity Mode)
< 2 s (90 %)
< 10 s (50 %), < 13 s (90 %)
< 38 s (50 %), < 42 s (90 %)
< 50 s (50 %), < 84 s (90 %)
Cold start requires no initialization.
Warm start implies last position, time, and
almanac are saved by backup power.
Hot start implies ephemeris also saved.
