The Position page will be displayed when the GPS 150 has locked on to satellites
and is ready for navigation. Note that if you begin using the GPS 150 in any way
before it has obtained a fix, it will not automatically display the Position page, but will
inform you when the GPS 150 is displaying current navigation information with the
‘Ready for navigation’ message.
Typically, if you turn on the GPS 150 when you leave the hangar, it will have
acquired satellites and be ready for navigation before you are ready to take off. Satellite
acquisition times can be as little as 15 seconds, or as long as 5 minutes. If the
antenna has a clear view of the sky, it should not take over 5 minutes, unless the unit
is acquiring new satellite data. This condition will be accompanied by a ‘Searching
the sky’ message.
If you are having trouble acquiring satellites on a routine basis, check the antenna
installation and cabling to the GPS 150 rack. If the installation appears to be in good
order, this may signal that there is a problem with the unit. If you feel there may be a
problem with your GPS 150, please contact your local avionics dealer.
