1 Introduction
Congratulations on your purchase of the Maretron GPS100 GPS/WAAS Antenna/Receiver.
Maretron has designed and built your GPS100 to the highest standards for years of reliable,
dependable, and accurate service.
The Maretron GPS100 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed and maintained in the correct manner. Please read carefully and follow these
instructions for installation and usage of the Maretron GPS100 in order to ensure optimal
performance.
1.1 Firmware Revision
This manual corresponds to GPS100 firmware revision 1.5.
1.2 GPS100 Features
The Maretron GPS100 has the following features.
• NMEA 2000® Interface
• 12 Channel GPS Antenna/Receiver
• Satellite Based Augmentation System (SBAS) capable (WAAS, EGNOS and MSAS)
• Accurate Location, COG and SOG Data to Any NMEA 2000® Device Including Chart
Plotters, Autopilots, and Instrumentation Displays
• Magnetic Variation Output Based on World Magnetic Model (WMM2005)
• Waterproof Enclosure and Cable System
2 Installation
2.1 Unpacking the Box
When unpacking the box containing the Maretron GPS100, you should find the following items:
1 - GPS100 GPS/WAAS Antenna/Receiver
1 - Pole Mount Base
3 - Mounting Screws and Lock Washers
1 - GPS100 User’s Manual
1 - Warranty Registration Card
If any of these items are missing or damaged, please contact Maretron.
2.2 Choosing a Mounting Location
The selection of a suitable mounting location is important for the optimal performance of the
Maretron GPS100. The mounting location and orientation of the GPS100 should be:
1. Level with the earth’s horizontal plane – This gives the GPS100 antenna the optimal view
of satellites from all directions.
Revision 1.2 Page 1
GPS100 User’s Manual
2. High Enough to have a clear view of the sky to the horizon in all directions unblocked by
masts or antennas – The GPS100 provides the best readings when it has access to as
many satellites as possible.
3. As far as possible from VHF, satellite, or radar antennas – Radio frequency transmissions
from these antennas can interfere with the proper reception of GPS satellite signals by the
GPS100.
2.3 Mounting the GPS100
The Maretron GPS100 can be mounted directly on top of a horizontal surface (Section 2.3.1)
or on top of a 1” 14 threads per inch standard marine pole mount (Section 2.3.2).
2.3.1 Mounting the GPS100 to a Horizontal Surface
Attach the GPS100 securely to the vessel using the included brass mounting screws and
included lock washers or other fasteners as shown in Figure 1 (see mounting template in
Section 8 for drill pattern).

2.3.2 Mounting the GPS100 to a Standard Marine Pole Mount
Screw the included GPS100 antenna mount base to the standard marine mount. Thread the
NMEA 2000® cable through the standard marine mount and the antenna mount base from the
bottom out through the top and connect it to the GPS100 unit (see Section 2.4 below). Finally,
attach the GPS100 to the antenna mount base using the included brass mounting screws and
lock washers as shown in Figure 2.

2.4 Connecting the GPS100
The Maretron GPS100 provides a connection to an NMEA 2000® interface through a
connector that can be found on the bottom of the device (see Figure 3).
Figure 3 – GPS100 Interface Connector
The NMEA 2000® connector is a five pin male connector (see Figure 4). You connect the
GPS100 to an NMEA 2000® network using a Maretron NMEA 2000® cable (or compatible
cable) by connecting the female end of the cable to the GPS100 (note the key on the male
connector and keyway on the female connector). Be sure the cable is connected securely and
that the collar on the cable connector is tightened firmly. Connect the other end of the cable
(male) to the NMEA 2000® network in the same manner. The GPS100 is designed such that
you can plug or unplug it from an NMEA 2000® network while the power to the network is
connected or disconnected. Please follow recommended practices for installing NMEA 2000®
network products.
