GPS Status
15.2.1 GPS Status Page
The GPS Status page provides a visual reference of GPS receiver functions,
including current satellite coverage, GPS receiver status, position accuracy, and
displays your present position (in latitude and longitude) and altitude.
The Satellite Status page is helpful in troubleshooting weak (or missing) signal
levels due to poor satellite coverage or installation problems. You may wish to
refer to this page occasionally to monitor GPS receiver performance and establish
a normal pattern for system operation. Should problems occur at a later date,
you may find it helpful to have an established baseline from which to compare.
