NAV PAGES

3-23

Each satellite has a 30-second data transmission that

must be collected (hollow

signal strength bar, see Figure

3-47) before the satellite may be used for navigation
(solid signal strength bar, see Figure 3-46). Once the GPS

receiver has determined the present position, the GNS 430
indicates position, track, and ground speed on the other
navigation pages. The

GPS receiver status field (Figure

3-46) also displays the messages listed in Table 3-5 under

the appropriate conditions:

GPS Receiver Status Messages

Searching Sky

The GPS receiver is searching the sky for ANY visible satellites. The
pilot is informed of this status with a ‘Searching the Sky’ message.

Acquiring Sat

The GPS receiver is acquiring satellites for navigation. In this mode,
the receiver uses satellite orbital data (collected continuously from
the satellites) and last known position to determine which satellites
should be in view.

2D Navigation

The GPS receiver is in 2D navigation mode. Altitude data is provided
by an altitude serializer.

3D Navigation

The GPS receiver is in 3D navigation mode and computes altitude
using satellite data.

Poor Coverg

The GPS receiver cannot acquire sufficient satellites for navigation.

Rcvr Not Usbl

The GPS receiver is unusable due to incorrect initialization or
abnormal satellite conditions. Turn the unit off and on again.

AutoLocate

The GPS receiver is looking for any available satellite. This process
can take up to five minutes to determine a position.

The Satellite Status Page also indicates the accuracy

of the position fix, using Estimated Position Error (EPE),
Dilution of Precision (DOP), and Horizontal Uncertainty
Level (HUL) figures. DOP measures satellite geometry
quality (i.e., number of satellites received and where they
are relative to each other) on a scale from one to ten. The

lowest numbers are the best accuracy and the highest
numbers are the worst.

EPE uses DOP and other factors

to calculate a horizontal position error, in feet or meters.
HUL is explained in Section 13.
