Differential GPS

Based on principle that GPS receiver on ground in a known

location, acts like a static reference point

Transmits the error correction message to other GPSreceiver to improve results.

POSITIONING ERRORS:

Correctable errorsNon Correctable errors

Provides advantage of

selective ability

MINE DETECTING SET

Detect mines and unexploded ammunitions.

Operating temperature : -30 degree to +55 degree .

Operating principle : Building up a magnetic field via

electric pulse to produce secondary field which is

picked by a receiver coil.


8/15

Harmonic Radar: Super Broom

Detects electronic components such as diodes, transistors, ICs

etc.

Does not react to components that do not contain

semiconductor materials.

Signal generated is pure radio

signal with a freq. of888.5 MHz for 1st harmonic

1777 MHz for 2nd harmonic

2666.5 MHz for 3rd harmonic

Automatic Electronic Switch(AES)

Integrated modular switch

Provides voice & data communication service

Uses two signals-

Hook

Highway.

Uses real time operating system(irk)

AES is of two types:

1). AES mark 1:-capacity 32cd,

192 voice channels,256 teleprinters.

2). AES mark 2:-capacity 60cd,

360 voice channels, 480 teleprinters

Working:

This laser based perimeter protection systemhaving -9 to +9 volt DC supply system.Transmitter card consists-IC LM/NE 567,LF 356.Receiver is tuned to the transmitter's

frequency.IC 567 is a CCO which generate a pulsedwaveform of frequency1 k Hz.Value of frequency is set by (1.1/R1C1).

IC356 & transistor (2N2222) is a output drivercircuit.


15/15

It drive the laser diode with a pulse amplitude 3V.

When an intruder tries to cross the unauthorized

Area or boundary, then the LASER link betweenthe transmitter and receiver is broken.

When laser beam is interrupted, diode act as open

circuit.Thus o/p of NIV amplifier become Low.

The pin-8 ofic goes LOW and the alarm connectedvia Buzzer is switched ON.

So the protection system is fool-proof and highlyreliable.
