Nav Mode
is the navigational status of GPS Fix. A 2-D (two
dimensional) fix only includes latitude and longitude data. A 3-D
(three dimensional) fix also includes altitude data. The available
constellation of satellites available affects whether altitude can
be calculated.
This GPS Info utility also has a Config menu that allows access to the following tools:
•
Cold Start
•
Settings
Cold Start
Should your MapSight unit be taking a long time to get a useable
GPS fix, the GPS can be forced to restart and require a completely
fresh almanac from available satellites. A full Cold Start and
almanac refresh can take up to 30 minutes depending on local
satellite coverage.
Tapping the [Yes] button at the ‘Do you really want to cold start
the GPS?’ prompt will flush all current information in the GPS and
force it to reacquire this data. Tapping [No] will cancel the Cold
Start request.
CAUTION
: Cold starting the GPS will reset GPS position
reception and will not result in an accurate or useable GPS
position fix until the new fix is achieved.
Settings
This is a shortcut to the MapSight Settings ‘GPS’ tab.
