2. INDUSTRIAL TRAINING AT KELTRON
INTRODUCTION
The Kerala state electronics development corporation(KSEDC) was established in
1977
First electronics development corporation in India in the state government sector
They introduce the state-of-the art technology in the field of control and
instrumentation
There is four self-profit generating strategic business unit (SBU) and they are
supported by a common service group (CSG’S)
Control and instrumentation
Pneumatic products
Information technology
Strategic service

3. 1. INFORMATION TECHNOLOGY GROUP (ITG)
• Keltron starts manufacturing of computers in 1999.
• Keltron has widened its IT horizon by enlarging its
production base, and entering other IT domains such as
software development, training and support services.
• Keltron computers are in use in all Government
Departments as well as the schools of the State.
• Entire IT infrastructure is planned, implemented and
maintained by Keltron.

4. 2.STRATEGIC SERVICES GROUP. (STSG)
• This group is in the threshold of more focused larger business from defense
departments
• Thereby the division is also fulfilling the social obligations to a certain extend
• fact the government of Kerala had best owed greater faith in Keltron by
declaring Keltron a Nodal Agency for fulfilling the requirements of
physically disabled.
• Latest product manufactured in STSG section s towed array which is
mainly used in defense applications.

5. 2.1 Towed Arrays
• Towed array sonar is a sonar array that is towed behind a submarine or surface
ship.
• It is basically a long cable, up to 5 km, with hydrophones that is trailed behind
the ship when deployed.
• Towed arrays are used for the detection of missiles and location of submarines
• A hydrophone is a microphone designed to be used underwater for recording or
listening to underwater sound

6. • Most hydrophones are based on a piezoelectric transducer that generates
electricity when subjected to a pressure change.
• A microphone can be buried in the ground, or immersed in water if it is put in
a waterproof container.
(Towed Array Illustration)
• On the first few hundred meters near the ship's propeller there are usually no
hydrophones since their effectiveness would be reduced by noise.
(continued..)

7. • usually only guaranteed when the cable is in a straight line, or else a GPS is
used to monitor the shape of the array.
• The hydrophone assembly consists of a hydrophone and a charge amplifier
• The data detected by the hydrophones is centrally processed to provide a
detection, mapping, etc.
• . It is thus important to also continually monitor the relative positions of the
nodal points of the array
• Presently used towed acoustic receiving arrays are very costly

8. (Working Of Towed Array)
o The hydrophone assembly consists of a hydrophone and a charge
amplifier.
o It has two functions of data acquisition and signal conditioning.
o The data taken in the analog form is converted into digital form in the
corresponding signal conditioning unit.
o This digital data is converted into optical form.

9. • They are thickly arranged for high frequency
applications and loosely arranged for low
frequency applications.
• Data detected by the hydrophones is centrally
processed to provide a detection, mapping,
etc.

10. CONCLUSION
The internship is successfully completed with in two
weeks from July 13, 2016
I was able to understood about the departments in
the company
Towed arrays and computers are the main products
of the company
