7.6 F.A.Q
7.6.1 I cannot see the vessel on the Internet AIS service
Websites providing AIS services like e.g. www.marinetraffic.com does not cover all the
seas of the world, but only specific coastal areas where AIS receivers have been
installed and that upload the data to the websites. The vessel must be in reception
range of these AIS receivers to show up on the Internet AIS service.
7.6.2 I can “see” the other vessel, but they do not “see” my vessel
There are several reasons why this might happen. The first thing to check is if the R5
SOLID is transmitting at all or if is transmitting in low power mode. In VHF Status view
described in section 4.24 it is possible to check the status on all R5 SOLID VHF
transceivers. Make sure that correct channels and power mode are used. There might
be a regional area set in the transponder that changes the operating mode of the R5
SOLID. Regional areas are listed in the Regional Area view (see section 4.17).
The MMSI must also be configured in order for the R5 SOLID to transmit. If the MMSI
is zero, the R5 SOLID will be silent.
Another possibility is that the other vessels’ transponder requires a shorter reception
range in order to receive the R5 SOLID transmissions. In the Target List view and the
Plot view it is possible to see the range and bearing to other vessels.
7.6.3 The VHF range seems to be short
As a general rule, the VHF range is equal to line of sight from the antenna position,
which means that the higher the antenna is installed, the longer the range will be. It is
also important to follow the guide lines for an antenna installation as thorough as
possible. Section 3.5.1 describes how to best install the VHF antenna.
7.6.4 I can only receive a few GPS satellites
The position of the GPS antenna is of high importance to optimize the GPS reception.
Follow the guide lines of GPS antenna installation described in section 3.6 “Mount the
R5 SOLID GPS Antenna” as thorough as possible.
