2. Before you start
The GPS150USB is a smart
“all in one” GPS/GLONASS receiver solution for small boats featuring our DualNav™
technology that allows the unit to be set to use the GPS or GLONASS satellite constellations or a combination of the two
systems. Select the mode you want the GPS150USB to operate in (see Section 4), connect it via USB to a
Windows/Mac/LINUX PC and it will immediately start calculating your position and outputting this data in NMEA 0183
format (4,800, 38,400 or 115,200 baud).
Carefully consider where you wish to mount the GPS150USB and how you will feed the 5m USB cable through to the PC.
Specialist cable glands are available online, that will allow cables with USB connectors to fit through them and we would
definitely recommend using these, rather than cutting, joining or fitting other connectors to the USB cable.
The maximum length of standard USB cables is 5m but special powered extension cables are available if it is necessary
to extend the GPS150USB cable. Digital Yacht can supply a 5m Powered USB Extension cable if required.
IMPORTANT: The GPS150USB should be connected directly to the computer
’s USB port and not via a USB Hub.
To display the GPS/GLONASS data you will need:
Suitable Windows/Mac/LINUX PC with a spare USB port.
The Digital Yacht Software and Drivers CD (supplied with the GPS150USB)
Suitable Navigation software running on the Windows/Mac/LINUX PC that can read GPS data.
3. Installation
Before starting installation select a suitable location for the GPS150USB Receiver. The unit features a very sensitive
GPS/GLONASS receiver and in many boats the GPS150USB will operate quite happily below deck or in a wheel house.
If you find that you are getting good performance with the GPS150USB mounted below deck, then installation is simple
and you just need to find a suitable location where the GPS150USB can be firmly fixed.
For absolute optimum performance, then on-deck
mounting is recommended and the unit is fully
water proof and designed for permanent mounting
outside. The GPS150USB antenna has the
popular 1” x 14 TPI thread mount, found in many
VHF antennas. A wide variety of different brackets
are available for this type of threaded mount,
consult your local marine electronics dealer or
chandlery for more information.
The 1” x 14 TPI thread mount can also be removed
by unscrewing the three hex bolts with a suitable
Allen Key, allowing the GPS150USB to be flush
mounted on a flat horizontal surface using M3 Nuts
and Bolts (not supplied). In this situation, the
antenna should be mounted on a layer of silicone
sealant to avoid standing water accumulating
under the antenna.
The GPS150USB is supplied with 5m of USB cable
and this should be routed through the vessel to a
suitable dry internal location where it can be
connected to the Windows/Mac/LINUX PC which
will provide power to the GPS150USB and receive
the GPS/GLONASS data from the GPS150USB.
