fully automatic and, under normal circumstances, will
take about 5 minutes to achieve a navigation solution.
However, the host system should allow the GPS 35/
36 to remain on for at least 12.5 minutes after the first
satellite is acquired (see Section 4 for more information
on status indications).
2) If the internal memory backup battery fails or is not
installed while the host system power is off and not
connected to standby power, the GPS 35/36 will
search the sky as described above. The system
designer should be aware of the availability of standby
power input to the GPS 35/36 to prevent this situation.
3) If the initial data is significantly inaccurate, the GPS
35/36 will perform an operation known as
AutoLocate
TM
. This procedure is fully automatic and,
under normal circumstances, will require about 5
minutes to calculate a navigation solution.
AutoLocate
TM
, unlike search the sky, does not require
that the GPS 35/36 continue to operate after a fix has
been obtained.
