Table 1: A1029 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.
(5) Receiver is powered off, clock stops. Start-up time depends on time passed since power-off and
power-on location.
(6) In order to improve TTFF, the receiver allows setting of time/date/position.
