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:

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.

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).

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.
