Indian Telegraph Act
The Indian Telegraph Act, 1885 is the enabling legislation in India which governs the use of wired and wireless telegraphy, telephones, teletype, radio communications and digital data communications. It gives the Government of India exclusive jurisdiction and privileges for establishing, maintaining, operating, licensing and oversight of all forms of wired and wireless communications within Indian territory. It also authorizes government law enforcement agencies to monitor/intercept communications and tap phone lines under conditions defined within the Indian Constitution. The act came into force on 1 October 1885. Since that time, numerous amendments have been passed to update the act to respond to changes in technology. Background The Indian Telegraph Act, passed in 1883, was intended to give the Central Government power to establish telegraph lines on private as well as public property. At the time the Act was conceived, India was still under the rule of the British Raj. Telegr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Legislative Council
The Imperial Legislative Council (ILC) was the legislature of the British Raj from 1861 to 1947. It was established under the Charter Act of 1853 by providing for the addition of 6 additional members to the Governor General Council for legislative purposes. Thus, the act separated the legislative and executive functions of the council and it was this body within the GG council which came to known as the Indian/Central Legislative Council. In 1861 it was renamed as Imperial Legislative Council and the strength was increased. It succeeded the Council of the Governor-General of India, and was succeeded by the Constituent Assembly of India and after 1950, was succeeded by Parliament of India. During the rule of the East India Company, the council of the Governor-General of India had both executive and legislative responsibilities. The council had four members elected by the Court of Directors. The first three members were permitted to participate on all occasions, but the fou ...

Amateur Station Operator's Certificate
Amateur radio or ham radio is practised by more than 22,000 licensed users in India. The first amateur radio operator was licensed in 1921, and by the mid-1930s, there were around 20 amateur radio operators in India. Amateur radio operators played an important part in the Indian independence movement with the establishment of illegal pro-independence radio stations in the 1940s. The three decades after India's independence saw only slow growth in the number of operators until the then Prime Minister of India and amateur radio operator, Rajiv Gandhi (VU2RG), waived the import duty on wireless equipment in 1984. Since then, numbers have picked up, and , there were more than 16,000 operators in the country. Amateur radio operators have played a vital role during disasters and national emergencies such as earthquakes, tsunamis, cyclones, floods, and bomb blasts, by providing voluntary emergency communications in the affected areas.

Wireless Planning And Coordination Wing
The Wireless Planning & Coordination Wing (WPC) is a Wing of Department of Telecommunications coming under the Ministry of Communications of the Government of India. The department is responsible for issuing amateur radio licenses, allotting the frequency spectrum and monitoring the frequency spectrum. The WPC is headquartered in New Delhi and has regional branches in Mumbai, Chennai, Kolkata and Guwahati. WPC is divided into major sections like Licensing and Regulation (LR), New Technology Group (NTG) and Standing Advisory Committee on Radio Frequency Allocation (SACFA). SACFA makes recommendations on major frequency allocation issues, formulation of the frequency allocation plan, making recommendations on the various issues related to International Telecom Union (ITU), to sort out problems referred to the committee by various wireless users, siting clearance of all wireless installations in the country, etc. Technical Group 'A' officers manning this organisation comes under cad ...

Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and '' amateur-satellite service'') is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which mus ...

RISAT-2
RISAT-2, or Radar Imaging Satellite-2 was an Indian radar imaging reconnaissance satellite that was part of India's RISAT programme. It was built by Indian Space Research Organisation (ISRO) and successfully launched aboard a PSLV-CA launch vehicle at 01:15:00 UTC on 20 April 2009 from the Second Launch Pad at the Satish Dhawan Space Centre. The principal sensor of RISAT-2 was an X-band synthetic-aperture radar (SAR) from Israel Aerospace Industries (IAI). It is designed to monitor India's borders and as part of anti-infiltration and anti-terrorist operations. The satellite has a mass of . History RISAT-2 was built at an accelerated pace following the 2008 Mumbai attacks, due to delay with the indigenously developed C-band for RISAT-1. It is India's first dedicated reconnaissance satellite. The X-band SAR used by RISAT-2 was obtained from Israel in return for launch services for the Israeli TecSAR-1 satellite. The SAR sensor enables RISAT-2 to return images at any time o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RISAT-1
Radar Imaging Satellite 1 or RISAT-1, was an Indian remote sensing satellite built by the Indian Space Research Organisation and operated by National Technical Research Organisation . The second RISAT satellite to be launched, it used a C-band 5.35 GHz synthetic-aperture radar (SAR) for Earth observation. The launch of RISAT-1 came several years after that of RISAT-2, which carried an Israeli-built X-band radar. The RISAT-2 mission was prioritised over RISAT-1 following the 2008 Mumbai attacks, resulting in RISAT-1 being delayed by several years. Satellite description RISAT-1 had a mass at liftoff of , making it the heaviest Earth observation satellite to be launched by India, and the heaviest satellite to be launched using a Polar Satellite Launch Vehicle. It had the capability to take images of Earth during day and night, as well as in cloudy conditions. The satellite is equipped with a 160 × 4 Mbit/s data handling system, 50 Newton-metre-second reaction wheels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RISAT
RISAT (Radar Imaging Satellite) is a series of Indian radar imaging reconnaissance satellites built by ISRO. They provide all-weather surveillance using synthetic aperture radars (SAR). The ''RISAT'' series are the first all-weather Earth observation satellites from ISRO. Previous Indian observation satellites relied primarily on optical and spectral sensors which were hampered by cloud cover. After the 26 November 2008, 2008 Mumbai attacks, the launch plan was modified to launch RISAT-2 before RISAT-1, since the indigenous C-band SAR to be used for RISAT-1 was not ready. RISAT-2 used an Israel Aerospace Industries (IAI) X-band SAR sensor similar to the one employed on TecSAR. Satellites RISAT 2 RISAT-2 was the last of the RISAT series to reach orbit. It was launched successfully on April 20, 2009 at 0015 hours GMT by a PSLV rocket. The 300-kg satellite was built by ISRO using a X-band SAR manufactured by IAI. This satellite was fast tracked in the aftermath of the 2008 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
