No fix
Possible causes
Possible solutions
No GNSS (GPS) receiver
connected.
In order to obtain a position fix your product requires a GNSS
(GPS) receiver. Your product may include an internal GNSS
(GPS) receiver, if not then an external GNSS (GPS) receiver
such as the RS150 is required.
No antenna connected to GNSS
(GPS) receiver.
Depending on variant, your product may include an internal
GNSS (GPS) receiver. The receiver may or may not include
an internal antenna. If your product’s internal GNSS (GPS)
receiver does not include an internal antenna then you will
need to connect an external passive antenna to the GNSS
(GPS) / GA150 connection.
GNSS (GPS) Antenna location.
For optimum performance, external GNSS (GPS) antennas and
GNSS (GPS) receivers that include an internal antenna should
be mounted above decks and have a clear, unobstructed
view of the sky, and not be in close proximity to any structural
bulkheads or other electrical equipment or cables which may
cause interference.
GNSS (GPS) switched off.
Ensure your internal GNSS (GPS) receiver is switched on in
the relevant settings menu.
Geographic location or prevailing
conditions preventing satellite fix.
Check periodically to see if a fix is obtained in better
conditions or another geographic location.
