7.1 GPS Check
Checking GPS operation
You can check that the GPS is functioning correctly
using the chart application.
1. Select the Chart page.
2. Check the screen.
With the chart displayed, you should see:
Your boat position (indicates a GPS fix) . Your
current position is represented by a boat symbol
or solid circle. Your position is also displayed in
the data bar under VES POS.
A solid circle on the chart indicates that neither
heading nor Course Over Ground (COG) data
is available.
Note: Raymarine recommends that you check the
displayed vessel position in the chart application
against your actual proximity to a known charted
object. GPS receivers typically have an accuracy
of between 5 and 15 m.
Note: A GPS Status screen is available within the
Setup menu of Raymarine multifunction displays.
This provides satellite signal strength and other
relevant information.
