Navigation Training Humminbird Field Test
Program Date December 4th, 2008
Special thanks to Keith Counsel for providing
this presentation.

GPS is an acronym for Global Positioning
System. GPS provides accurate position
(latitude, longitude, altitude) information
virtually anywhere on the earth through satellite
technology and personal receivers on the ground.
A series of geosynchronous satellites broadcast
a unique signal toward the earth once per second.
A GPS receiver, receives the signals from these
satellites and is able to determine position
based on very slight differences in the time each
signal is received and the receivers knowledge
of the location of each of the satellites.

GPS Terms

COG- Course Over Ground Course Over Ground is
the current direction the boat is traveling
measured in degrees from North (where 000 is
North, 090 East, 180 is South, 270 is West).
When the Course Over Ground is equal to Bearing,
the boat is said to be On Course and will
arrive at the destination in the most efficient
manner.
N
45deg
290deg
5
SOG- Speed Over Ground Speed Over Ground is the
measurement of the boats progress across a given
distance the speed measurement provided by GPS
accurate destination times can be derived from
this measurement.
SPEED
6
Water Speed The current speed of the water as
it flows past the boat. (Must have optional TSW
or SW Speed Sensor installed)
7
Bearing Bearing is the direction to a
destination waypoint measured in degrees from
North (i.e. 321, where 000 is North, 090 East,
180 is South, 270 is West).
N

290deg

VMG- Velocity Made Good Velocity Made Good is
the speed of travel relative to the next waypoint
on the route. The goal is for VMG to equal Speed.
Actual Course
Next to each orange line is it useful speed
7 mph
10 mph
6 mph
Waypoint
Best Course
10mph
Start Actual speed always 10mph
9
VMG- Velocity Made Good Commonly used in sailing
Wind
Is it better to go slower into the wind or faster
a little more off the wind? Say red and green
arrive at the same time because red was going at
a fast speed its VMG was the same as the boat
going on the more direct course at a slower speed.
10
XTE- Cross Track Error Cross Track Error is the
straight-line distance of the boat from the
intended Track. XTE measures how far the boat is
off course, and also triggers the Off Course
Alarm.

Date, Time, speed, course, and Altitude are all
calculated from the GPS signal we receive. It
takes about 12-13 mins for a 100 signal to be
accrued but we start to have acceptable signal
from 30sec to 2mins. Internal GPS units do take
longer to accrue signals.
13
Fix Type - (No Fix, 2D Fix, 3D Fix, Enhanced.)
Enhanced fix means we have started to use info
from WAAS. HDOP - Horizontal Dilution or
Precision - This data comes from the current
satellite configuration. We will run any were
from 0.6 to 3 normal. Lower number means
better. EPE - (Estimated Position Error) unit
take a number of factors to calculate an
ESTIMATED possible error. (2.5m is our call out)
14
What is WAAS? WAAS Wide Area Augmentation
System. WAAS is a complementary technology to
GPS that provides enhanced accuracy through
correction signals broadcast from Federal
Aviation Administration WAAS satellites stationed
over the USA. These secondary signals are
automatically received by most GPS Receivers.
With WAAS signal, GPS accuracy is improved to
within 3 meters 95 of the time. Outside the
United States, regional governmental coalitions
have created similar systems such as EGNOS
(Europe) and MSAS (Japan).

Main Menu- NAV Tab
16
Main Menu- Nav Tab Current Track Color By Depth
17
Main Menu- Nav Tab Saved Track Same options as
Current Track but you must select the track you
want to affect. Good thing to note- say you have
a track that you do not want to get rid of but do
not want to see. You can do this via this menu
option (edit).
18
Main Menu- Nav Tab Waypoints
19
Main Menu- Nav Tab Routes Routes are multiple
destinations navigation that you want to get to
On water you can go as the crow flies often,
but some times you need to go around a island,
stump field, or some other no-entry area, that is
where routes come in.

23
Main Menu- Nav Tab Trolling Grid Rotation
Why use this?- Girds are great way to ensure you
do not go back over area already covered, by
rotating it you get a reference. Why only
89deg?- 90deg is 0deg, it is a square.
24
Main Menu- Nav Tab Trackpoint Interval and Track
Min Distance These two actually work
together. Let say you are moving at 60 per
min. Now you have your trackpoint interval at 1
second and Track Min Distance at 16 That means
the trackpoint interval is saying put a
trackpoint every 1sec but the min distance says
no you must be at least 16 away from the
last. Let see if I can explain this better
25
Main Menu- Nav Tab Trackpoint Interval and Track
Min Distance - Example - Speed 60 per min (1
per sec)
Trackpoint Interval- 1 sec Track Min Distance-
5 Trackpoint Interval- 5 sec Track Min
Distance- 1 Trackpoint Interval- 1 sec Track
Min Distance- 10 Trackpoint Interval- 20
sec Track Min Distance- 1 Trackpoint Interval-
1 sec Track Min Distance- 50 Why is
this useful? - You are limited on the total
number of trackpoints in the unit!

Main Menu- Nav Tab Export and Delete all Nav
Data Export and Delete only affect saved Tracks,
not your current track! For export to work you
must have an SD card in the unit.
31
Main Menu- Nav Tab Continuous Navigation
Mode What does it do? If you are navigating to a
point, when you arrive, the unit does not stop
navigating to that point unless you cancel. Why
is this useful? No anchor zones or you want to
not anchor and stay over the same point or near
the same point.
32
Main Menu- Nav Tab GPS Receiver Override This
lets you choose which GPS receiver to useif they
are connected. Order Auto InterLink

Navionics Platinum Platinum Options
Features New Menu Satellite overlays. Overlays
only go so far away from shore, remember these
are marine maps. Ability to adjust how
transparent the overlay is.
36
Navionics Platinum Platinum Options
New Features Pilot Book- contains detailed info
on the port (depends heavy on what Navionics has)
This is a new screen called Chart plus pilot
book view Cursor thought by using the cursor
button and goto button. If you press info and
select port then you can get the traditional port
info, the pilot book entry for that port or an
aerial photo of the port.

Main Menu- Chart Tab Map Borders
Navionics data is made up of thousands of
maps Even Uni-map is made of multiple
maps (Uni-map is a Navionics Product that we
purchased.)

Main Menu- Chart Tab Shaded Depth
Something interesting people are doing with
shaded depth is if the water level is extremely
low on their lake they are using the shaded depth
to give them a new outline of the lake.
48
Main Menu- Chart Tab Chart Select Allows someone
override the unit chart selection
49
Main Menu- Chart Tab NVB Chart Preference (only
in NVB units) Allows a user to choice which
chart type to use.
50
Main Menu- Chart Tab NVB Chart Preference(only in
NVB units) Why would you want to be able to do
this? Can occur is areas where Gold and Hotmaps
meet.
51
Main Menu- Chart Tab Set Simulator Location This
will allow you to start up in simulator mode
where ever you set it too. Default is Miami on
Domestic units and England on International
units. Cursor to the location then go to Set
Simulator Location
52
Main Menu- Chart Tab Map offset Cursor to the
location then go to Set Map Offset
Map Offset does not affect GPS or waypoint
position.
In order to make another offset you must clear
the active map offset first if active, clear
Map offset will be in the menu where Set Map
Offset was.

MOB- Man Over Board
Press and hold the GoTo Button, once MOB mode
starts you must cancel in order to do any other
navigation
The Waypoint name means something MOB06141130
means MOB on 06/14 at 1130
