GPS module:

The screen provides means to switch the GPS Module between the „<µBlox>‟ or „<Jupiter>‟.

You can force the AIS to search again for the GPS Module installed. Selecting the wrong type

of GPS module may result in invalid position information and/or malfunction so that your AIS

can not operate correct. Select and with [Left] & [Right] arrows the option <SEARCH>to

search which module is installed Please mention the system will restart automatically when

saving these setting later. .

Position Pinning:

The screen provides means to switch the position pinning function of the internal GPS

receiver on and off. For vessels operating with SOG < 0,3 knots it is recommended to switch

position pinning off. Otherwise the internal GPS receiver may deliver wrong position

information.

The data input field is fitted with the recommended default value (<on>). The M6 button is

used for toggling between the two modes of position pinning; the M5 button is used for saving

the settings.

NOTE: The system will be restarted after saving the settings.

<µBlox> GPS Receiver:

This GPS receiver is installed in later versions of NAUTICAST. It is designed for use with

passive and active antennas. The recommended GPS antenna should have a minimum gain

of 15 - 20 dB to compensate signal loss in RF cable. The supplied ACR – GPS antenna is a

active type and has a gain of +30dB it is able to dive cable lengths of 45 meters. Antennas

with more than 50 dB should not be used. This high signal level can damage the GPS

receiver.

<Jupiter> GPS receiver:

As described above, the resulting installation gain should be between 0 to 10 dB. If the

internal GPS receiver will be overloaded with more than 18dB, then it could be damaged.
