Electronic corporation of India (ECIL)
Submitted by Nagelli Srikanth Goud(11bec0244)
About the company ECIL was setup under the Department of Atomic Energy on 11th April, 1967 with a view to generate a strong indigenous capability in the field of professional grade electronics. The initial accent was on total self-reliance and ECIL was engaged in the Design, Development, Manufacture and Marketing of several products with emphasis on three technology lines viz. Computers, Control Systems and Communications. Over the years, ECIL pioneered the development of various complex electronics products without any external technological help and scored several 'firsts' in these fields prominent among them being country's
First Digital Computer
First Solid State TV
First Control & Instrumentation of Nuclear Power Plants
First Earth Station Antenna
First Computerized Operator Information System
First Radiation Monitoring & Detection Systems
First Automatic Message Switching Systems
First Operation & Maintenance Center For E-108 Exchange
First Programmable Logic Controller
First Solid State Cockpit Voice Recorder
First Electronic Voting Machines
The company played a very significant role in the training and growth of high caliber technical and managerial manpower especially in the fields of Computers and Information Technology. Though the initial thrust was on meeting the Control & Instrumentation requirements of the Nuclear Power Program, the expanded scope of self-reliance pursued by ECIL enabled the company to develop various products to cater to the needs of Defence, Civil Aviation, Information & Broadcasting, Telecommunications, Insurance, Banking, Police, and Para-Military Forces, Oil & Gas, Power, Space Education, Health, Agriculture, Steel and Coal sectors and various user departments in the Government domain. ECIL thus evolved as a multi-product company serving multiple sectors of Indian economy with emphasis on import of country substitution and development of products & services that are of economic and strategic significance to the country.

HF/VHF RADIOSWeek 1
Different types of Radios are used for different mode of communication based on the assigned frequency spectrum for different purpose . VHF: Man to Man ( Manpacks)
UHF: Ground to Air for Close Support
HF: Around the Corner to Around the World
HF RADIOVHF RADIO
Frequency allocation
Available Radio Frequency
Contd..usable frequency range for radio waves extends from about 20 kHz (just above sound waves) to above 30,000 MHz High Frequency (HF) Band :3 to 30 MHzVery High Frequency (VHF) Band: 30 to 300 MHz Ultra High Frequency (UHF) Band : 300 MHz to 2450 MHz
SECURING COMMUNICATIONS
Digital EncryptionTransmission security (TRANSEC)
Information security is becoming a high priority for businesses around the world. With the dramatic increase in electronic communications and electronic commerce, there has been a corresponding increase in the malicious compromise of that information. In order to reduce this different communications security techniques are employed

EMI/EMC LABWeek 2
Electromagnetic Interference (EMI) : It is defined as electromagnetic energy from sources external or internal to electrical or electronic equipment that adversely affects equipment by creating undesirable responses (degraded performance or malfunctions). Electromagnetic Compatibility (EMC) : It is defined as an electrical system's ability to perform its specified functions in the presence of electrical noise generated either internally or externally by other systems. The goal of EMC is to minimize the influence of electrical noise. EMI/EMC testing is designed to ensure that electrical/electronic equipment will perform properly in its expected electromagnetic environment, thus maintaining an acceptable degree of Electromagnetic Compatibility (EMC

Anechoic Chambers
The walls, ceilings and floor are lined with special electromagnetic wave absorbing material. Indoor ranges are desirable because the test conditions can be much more tightly controlled than that of outdoor ranges. The material is often jagged in shape as well, making these chambers quite interesting to see. The jagged triangle shapes are designed so that what is reflected from them tends to spread in random directions, and what is added together from all the random reflections tends to add incoherently and is thus suppressed further.

MACE TELESCOPEVery High Energy (VHE) gamma - rays offer a unique insight into some of the most extreme regions of our universe. These exceptionally energetic photons need huge Telescopes that can collect the gamma-rays.MACE (Major Atmospheric Cherenkov Experiment ) will enable study of cosmic rays between 20 and 100 Gev and upto 5 Tev. It is the world’s largest telescope at the highest altitude. It will be remotely operated and will run on solar power. When a VHE gamma-ray enters theEarth’s atmosphere, it generates a showerof secondary charged particles which inturn cause a flash of blue Cherenkov light, which lasts for just ten thousand millionths of a second. To detect the flashes of Cherenkov light, photomultiplier tube cameras are used at the focus of large Telescope.
21m MACE Telescope Components
It is comprised of a large area tessellated light collector (356sqm), made up of 356 mirror panels. A high resolution Imaging camera (weighing about 1500 Kgs) for detection and quantification of the atmospheric Cherenkov events forms the focal plane instrumentation of the telescope. The elevation over azimuth mounted telescope basket structure has two axes movement capability ±2700 in azimuth and -260 to +1650 in elevation for pointing towards and tracking any direction in the sky in the 00 to 700 Zenithal angle range .The novel feature of the telescope is the design of the integrated imaging camera, which contains 832 photomultiplier-based pixels and all the signal processing and data acquisition electronics.
