Preface
Safety Precautions
zBe Sure to "Disconnect" Inboard Power Supply
It is still possible to receive an electric shock caused by unintentionally switching on
the power supply during maintenance work. To prevent this from happening, be sure
to disconnect the inboard power supply and the power supply switch of equipment.
Place a notice "Men working" near the power supply switch of equipment to ensure
safety.
zBe Careful about Dust
Dust can cause temporarily the respiratory diseases. While cleaning inside of
equipment, be careful not to inhale dust. It is advisable to wear a safety mask etc.
zTake Countermeasures against Static Electricity
Carpets laid on the floor and synthetic fiber clothes can generate static electricity, and
can damage the electronic parts on the printed circuit boards. Take appropriate
countermeasures against static electricity before handling the printed circuit boards.

Chapter 1 Overview
1.1 About GPS
1.1.1 GPS satellite alignment
GPS (Global Positioning System) is a position measuring system that uses 4 satellites for each of 6
orbits, with durations of 11 hours 58 minutes, orbiting approximately 20,000km above the earth.
1.1.2 GPS system configuration
GPS is based on the principle of calculating the distance of 3 or more satellites from the user and
deriving the user’s position. The intersecting points of the sphere with the satellite located at its origin
indicate the current position (latitude, longitude, and altitude) measured by you.
Note: GPS uses the WGS (World Geodetic System) coordinate system. Previous
global maps used different coordinate systems for different zones.
The nautical chart of WGS coordinate system and the nautical chart of
non-WGS coordinate system may be different in the latitude and longitude.
1.2 About DGPS, SBAS
DGPS (differential GPS) can improve the GPS positioning accuracy in coastal waters. To get DGPS
positioning, you require a differential GPS navigator. The system works as follows.
Your GPS navigator gets position data from satellites (measured by the GPS) and combines this with
correction data from a DGPS reference station (existing radio beacon station).
The DGPS station compares the known surveyed position of the station itself with current position
information from the GPS system and calculates the error based on this data. The DGPS station then
sends correction data via (RTCM SC-104 format) using the beacon transmitter and to your DGPS
receiver module. The DGPS receiver module receives this information and applies this correction to
your navigator.
The accuracy is higher the closer you are to the beacon station. Generally speaking, the DGPS
system can be used within 100 to 200 nautical miles from the reference station.
SBAS is a robust system designed to improve the accuracy of GPS positioning using geostationary
satellites that are currently being developed in the US, Europe and Japan. There are 3 types of
systems being developed: WAAS in the US, EGNOS in Europe and MSAS in Japan. WAAS and
EGNOS are in operation. MSAS is going through application testing and is transmitting position
correction data at the same frequency as GPS satellites. Because position correction data is
transmitted from geostationary satellites, it is possible to receive position correction data anywhere in
the world. However, in case of application testing, the quality of the position correction data may be
degraded depending on the time.

1.3 Equipment outline
The KBG-3 incorporates an 18-channel parallel GPS receiver sensor that corresponds to SBAS. It
also incorporates a DGPS beacon receiver. It is a high-performance DGPS sensor. By simply
connecting a power supply, highly accurate position data can be quickly supplied to a Plotter or the
ship’s navigation devices.
When the unit is shipped out from the factory, it is initially set for automatic DGPS mode (Differential
GPS by beacon signal) and at automatically selects the best beacon station to use by just turning on
the unit. Of SBAS correction or manual selection of a beacon station is required, please setup the unit
by referring to the operation manual of KBG-3 and the interlaced navigation equipment. Setup may not
be effective sometimes except connection to Koden plotters.
1.4 Applicable standard
The KBG-3 conforms to the technical criteria of international standard that specifies General
Requirements of Maritime Navigation and Radiocommunication Equipment and Systems, IEC 60945
(Ed.4).
