ACQUIRING SATELLITES & VIEWING MESSAGES
The satellite status page will appear as the GNS 530 will begin to collect satellite
information. An 'Acquiring' status will be displayed on the satellite status page, and the
signal strength of any satellites received will appear as 'bar graph' readings. This is a
good indication that you are receiving signals and a position fix will be determined.
Following the first-time use of your GNS 530, the time required for a position fix will
vary - usually from one to two minutes.
If the unit can only obtain enough satellites for 2D navigation (no altitude), the unit will
use the altitude provided by the altitude encoder.
If the GNS 530 has not been operated for a period of six months or more, it may have
to 'Search the Sky' to collect new data. This means the unit is acquiring satellite data
to establish almanac and satellite orbit information, which can take 5 to 10 minutes.
The satellite status page will display a 'Searching Sky' status, and the message
annunciator (MSG), above the MSG key, will also flash to alert you of a system
message, 'Searching the Sky'.
To view a system message, press MSG.
