GPS
Status
The GPS Status screen contains information about signals
received from visible satellites in the sky.
The GPS information screen tells you:
•
The type of position fix currently calculated by the unit:
0D: no signals available
2D: the position fix is calculated based on signals from
only three satellites and GPS altitude is not available
3D: the position fix is calculated based on signals from
four or more satellites, and GPS altitude is available
•
The total number of operational GPS satellites in orbit
•
The number of satellites visible in the sky from your
position and their status
•
The Dilution of Precision (DOP) value for the position
fix provided by the satellite constellation - a high value
(6 or greater) indicates poor position reliability, while a
value of 3 or less indicates good position reliability
In addition, individual satellite information is available by
pressing the
buttons, as follows:
•
The strength of the received signal from each satellite
•
The satellite azimuth and elevation from the current
position
•
The GPS receiver’s current track status for each visible
satellite
Messages The
Precedus
helps you navigate by informing you of
important events or conditions while you fly. When an
important event or condition occurs, an alert message shows
on the display to inform you. When you see one of these
alerts on the display, follow the instruction shown to clear it.
Clearing the alert removes it from the display. The screen
shown before the alert appeared returns to the display. Alerts
may show on the display anytime the unit is operating.
