Navigation Overview
Global Positioning System (GPS) has developed for many years. It has been
upgraded from stand-alone GPS accurate to 100m which can only be applied
for rough navigation and positioning to real-time differential GPS (DGPS)
accurate to several centimeters which can be applied in various measurement
fields. GPS technology has become increasingly mature, varieties of products
have been produced, and there are more and more users applying DGPS
technology.
As the world's most popular positioning method, DGPS has been widely
applied in marine sounding, waterway survey, engineering exploration
orientation, cadastral survey, terrain cadastral survey, boundary demarcation,
harbor piloting, navigation of geophysical prospecting and hydrocarbon
exploration and staking of seismic shot and other measurement fields. Thus,
a measuring software which can realize multiple functions is needed.
The software is compatible to a variety of import and domestic GPS receivers.
It is a measuring tool software integrating measurement, editing and other
multiple functions with task-based operating mode and fool operation
interface. Adhering to the purpose of high and new technology popularization
as well as plebification. The software will appreciate the users relying on
more economical price as well as intelligent operation.
Principle of Echo sounder
Echo sounding principle
It is assumed that the sound speed under water is V. In case of a pulse
acoustic signal being loaded on a transducer, acoustic wave is transmitted
from the transducer to the seabed and then back. The time of acoustic signal
round trip is t, then:
Page 9
HD-MAX Echo Sounder User Guide
9
Z = V*t/2
Figure 1-1
Z is the depth from the transducer to the seabed, plus transducer draft.
Underwater signal recognition
Although the principle of depth sounding is simple, the situation in the water
is very complicated with parasitic echo, haunted by fish or clutter echo and
different reflection conditions at water bottom. In shoal waters, second trip
echo, triple transit echo may turn up. Relevant technology has to be adopted
on how to track the real underwater echo signal from numerous clutters.
Water bottom gate tracking technology (time gate tracking technology)
Since variations at water bottom are relatively flat, the sounding changes
between two times of depth sounding (about 0.1s) are not too big. Assuming
that the variation of secondary depth is ±10%, a time gate will be set
between 10%*Z before the last correct echo to the next 10%*Z. Only those
echoes within the time gate are correct ones, the ±10% range is referred to
as time door width. Once there is no echo within the time gate, it will
gradually expand the time door until entire echo searching until capturing the
correct echo.
Page 10
HD-MAX Echo Sounder User Guide
10
Figure 1-2
Pulse width selection
In most instances, the echo pulse width at water bottom surface is the Max..
The pulse width of interfering signal and second trip echo are relatively
smaller. Pulse width option is to identify the pulse with the Max. pulse width
as correct echo signal together with time gate.
Signal threshold
If there are more interferences within your measurement area or environment,
signal threshold settings are to be increased thus to filter out interfering
signals. However, signal threshold cannot be too high. Otherwise, it will
also filter out weak echo signal. Different thresholds can affect sounding
accuracy to a certain extent. Thus selection of appropriate signal threshold is
in favor of interference inhibition and stable tracking.
Gain control
Gain control technology is to control amplifying circuit and reduce the gain
in case of too high echo signal to prevent too much interfering signals by
measuring the signal intensity of echo-pulse. When the echo signal is too
small, it will control and receive amplifying circuit automatically and
increase the gain thus to receive echo. The size of gain range is a key factor
to measure receiver performance. The receiving gain control range of
HD-MAX Echo Sounder is 90Db by adopting manual gain control (MGC).
Page 11
HD-MAX Echo Sounder User Guide
11
Time varying gain (TVG)
When the acoustic wave propagates in water, sound intensity will attenuate
according to exponential laws. To maintain stable signal amplitude, TVG will
control the receiving amplifier to increase magnification according to
contrary law, which is the so called TVG.

48
WGS84 is adopted as source ellipsoid and Beijing 54 as local ellipsoid in
China.
Figure 7-4 Ellipsoidal parameter
Projector setting
The role of projection parameters is to achieve the transformation from space
rectangular coordinate system to plane rectangular coordinate system.
Choosing different projection methods will obtain different plane coordinates
correspondingly. The most frequently-used projective modes include
"Mercator", "Transverse Mercator", "Gauss -define" and so on.
Figure 7-5 Projective modes
Major parameters of projective modes setting include central meridian, north
with constants, east with constants, scale etc.. Generally, north with constants,
east with constants, scale are fixed constants. Users only need to set the

Figure 7-8 Seven-parameter
Description of several commonly used Ellipsoid transformation parameters
(1) Bursa-Wolf
Transformation, rotation and scale parameters at spatial vector between two
ellipsoids with extremely small rotation angle is a rigorous transformation
model. At least, three points are required for calculating. It is applicable to
transformation from WGS-84 to national coordinate system.
(2) Molodensky
It is a simplifying form of Bursa-Wolf method, only with transformation
parameters at spatial vector. It is a transformation method with lower
precision. It can calculate from a given point. It is applicable to
transformation from WGS-84 to national coordinate system.
(3) One-touch
Combination of transformation, rotation, scale parameters as well as plane
transformation parameters at spatial vector between two ellipsoids. The
rotation angle can be as an arbitrary value. At least, three points are required
for calculating. It is applicable to transformation from WGS-84 to any
coordinate system.

Attention: Users shall pay attention to coherent units of
seven-parameter. Especially when the "K" value dimensional unit is
ppm (percent per million), users shall pay more attention at
inputting!
Plane transformation
Plane transformation parameters refer to transformation from
plane-coordinate system to local ellipsoid plane coordinate system after
completing source ellipsoid projection. The frequently-used conversion
methods include: 2D Helmert, TGO, Grid etc.
Figure 7-9 Plane transformation model
Set up parameters based on the selected model, or acquire the parameters
through Utilities, such as 2D Helmert:

Figure 7-10 2D Helmert
Description of several commonly used plane transformation parameters
(1) 2D Helmert
Transformation, rotation and scaling parameters between two
plane-coordinate systems. It is applicable to most common engineering users.
Parametric solution can be performed from the known coordinates of two
arbitrary coordinate systems.
(2) TGO
A plane transformation method of TGO software. Comparing to 2D Helmert,
origin of coordinate north and origin of coordinate east are increased.
(3) Grid
Call-in the edited grid file format to WGS-84 coordinate transformation to
grid coordinate.
(4) FreeSurvey
It is a plane transformation method self-defined by THALES. Comparing to
four-parameter, origin of coordinate north and origin of coordinate east are
increased.
Height Fitting
Page 53
HD-MAX Echo Sounder User Guide
53
Height fitting is parameter correction to elevation fitting. Generally, it is
jointly used together with plane transformation parameters. The
frequently-used Polynomial fitting parameters include: Geometric Surface,
TGO, Grid, FreeSurvey Height fitting, and elevation fitting pattern
description etc.
Figure 7-11 Elevation fitting model
According to the fitting method selected, generally select "Constant" of "
Geometric Surface". Equations are obtained through inputting parameters or
elevation fitting algorithm of [UtilityTools], such as parameter fitting and
plane fitting:
Figure 7-12 Fixed difference correction
Description of several commonly used elevation fitting parameters:
(1) Geometric Surface
Constant correction: Take GPS measured elevation and the fixed constant as
operational elevation. Only a starting point is required.
Plane fitting: An optimal fitting plane will be generated corresponding to
height anomaly at multiple benchmarks based on three starting points. When
the plan is parallel to horizontal plane, the plane fitting is equal to fixed
difference correction.
Page 54
HD-MAX Echo Sounder User Guide
54
Quadratic Surface fitting: An optimal fitting paraboloid will be generated
corresponding to height anomaly at multiple benchmarks based on five
starting points. Quadratic Surface fitting is subjected to stricter start counting.
If the fitting degree is too poor, it may cause elevation correction value
divergence in the working area.
(2) TGO
Elevation transformation model of Trimble TGO software include five
parameters: constant balancing, northern slope, eastern slope, the origin of
north and the origin of east.
(3) Grid fitting
Grid fitting requires to select grid file fitting to support Trimble (ggf),
HI-TARGET (zgf), Geoid99 (bin) which can be compatible with egm-9
model. Generally, grid fitting files are great in size. Thus it may require more
time for reading. The grid fitting is rarely used in China at present. If "grid
fitting" and the other four elevation fitting methods are applied
simultaneously, perform "grid fitting" prior to other fitting methods.
(4) Free Survey Height fitting
Elevation transformation model of Trimble includes five parameters: constant
HO, northern slope, eastern slope, origin latitude and original longitude.

Points translation
Generally speaking, points translation (TruckPoint) only has one known
point in the working area. The GPS differential mode adopted by users is
code differential (beacon or SBAS). Besides, in case of no other translation
parameters, coordinate correction is to be performed to ensure measurement
accuracy. It is similar to fixed difference correction of the previous ocean
sounding software. The only difference is that the plus-minus signs of input
value are opposite.
dx, dy and dh can be entered as translation parameter directly. Or you can
obtain accurate translation parameter through point translation parameter
calculation tools in [UtilityTools].
Figure 7-14 Points translation
Attention: The points translation parameters of the software are
consistent with that of Hi-RTK hand book software.
However the fixed correction parameters of previous
software are different and the plus-minus signs of parameters
are opposite. For example, the fixed difference of previous
software can be input as dx, dy, dh. And for the software, the
translation parameters should be input as -dx, -dy and -dh.

Conclusion of This Chapter
Coordinate parameter setting is an essential link for measurement setup
which determines local coordinate precision directly. Generally, there are two
types of coordinate transformation methods, seven-parameter, and
four-parameter plus elevation fitting. If transformation parameters of local
coordinate system are provided, the user only needs to input corresponding
parameter. If not, it is necessary to solve the transformation parameters.
When the number of known points is more than three, generally,
seven-parameter will be applied; when the number of known points is two,
four-parameter plus elevation fitting will be applied.

Ship Design
At the software main menu interface, click [BoatShape] to enter the design
interface. The outer contour of the ship can be designed. The instrument
installation parameters can be setup.
Figure 9-1 Ship Design
Design outer contour of the ship: Select existing ship model or import hull
outline data in DXF format. Set up the length and width of the ship. The
software will perform self-adapting calculation according to hull model and
width to generate outer contour of the ship. The outside contour line of the
hull will affect visual effects of ship but without any effects on acquisition
data.
Instrument installation parameters setup: Select installation position of
transducer. [Left Side], [Right Side] or [Custom] are optional. The
self-defined settings will select green squares to move forward as shown in
the schematic diagram. Set the deviation between GPS antenna
position to transducer. Instrument installation parameters will affect the
measured result data thus they should be measured accurately.
Attention: At positions near to bow, there are more waves and
bubbles which will generate great interference on sounding of Echo
sounder. While at positions near to the stern, the waves and bubbles
generated by propeller will generate great interference on sounding
of Echo sounder as well. Therefore, the optimal installation position
of transducer is at the middle section of the ship. Generally, the
transducer is subordinate to stroke-side or starboard. If the actual
installation location is at the other position, select [Left Side] or
[Right Side] if it is installed at a position close to stroke-side or
starboard correspondingly.

Conclusion of This Chapter
For ship design, ship model as well as the width of the hull will not affect the
measuring result data. Users only need to input approximate values of hull
length and width. (Only the deviation parameter of GPS antenna position and
transducer position will affect measuring results. The parameters need
accurate measurement.)
