Table 1: A2235-H GPS characteristics

(1) The calibrated clock of the receiver has not stopped, thus it knows precise time (to the µs level).

(2) The receiver has estimates of time/date/position and valid almanac and ephemeris data.

(3) The receiver has estimates of time/date/position and recent almanac.

(4) The receiver has no estimate of time/date/position, and no recent almanac.

Note: Performance (sensitivity and TTFF) might slightly decrease below -30°C.
