  1. View Hint View Answer Discuss in Forum

    INS stands for Indian Navy Ship. INS was anchored off near Colaba in Mumbai. It is a Naval Hospital Ship. INHS Asvini has the distinction of emerging as the first Armed Forces Hospital with networked radiology images, sourced principally from a recently installed Digital Substraction Angiography (DSA) machine (Siemens Polystar Top 1000 MA). In recent times, newer imaging machines offer digital images that are in DICOM format. DICOM denotes ‘Digital Imaging and Communications in Medicine”. Image management at INHS Asvini, involves transfer of DSA images in DICOM format, their conversion into Joint Photographic Experts Group (JPG) format and subsequent transmission of JPG images through a robust networking system that connects all departments/OPD/Wards, facilitating direct access of images to a variety of specialists and specialities. INHS Asvini is the principal Command Hospital of the Indian Navy with a 825 bed teaching facility. It is presently undergoing modernization, underscored by the rapid induction of ‘state of art’ medical equipment along with continual computerization and networking of various Departments, Wards and OPD.

    Agni-II is a medium range ballistic missile (MRBM) with two solid fuel stages and a Post Boost Vehicle (PBV) integrated into the missile’s Re-entry Vehicle (RV). When the Agni-II was first launched, then Defence Minister George Fernandes indicated that the maximum range of the Agni-II was 3,000 km. Since then, ranges from 2,000 km to 2,500 km have been stated, while Dr. Kalam, at Aero India ’98, stated that Agni-II had a maximum range of 3,700 km. The Agni’s manoeuvring RV is made of a carbon-carbon composite material that is light and able to sustain high thermal stresses of re-entry, in a variety of trajectories. The Ghauri-II is a medium-range ballistic missile (MRBM). A longer ranged variant of the GhauriI, it was developed by increasing the length of the motor assembly and using improved propellants. The Ghauri-II missile has a maximum range of 2,000 km.

    INSAT-3A, a multipurpose satellite built by ISRO was launched by Ariane in April 2003. It is located at 93.5 degree East longitude. It is third satellite in INSAT-3 series after INSAT-3B & INSAT-3C.Built at a cost of $53 mn, it will provide communication, weather and search & rescue services. INSAT 3A was launched by Ariane-5 launch vehicle of Arianespace on April 10, 2003 at 4.22 am IST from Kourou, French Guyana. It was placed into a Geosynchronous Transfer Orbit (GTO), 30 minutes after the lift-off in 3-axis stabilized mode.
    Note : On August 27, 2015, ISRO successfully launched the GSLV-D6 spacecraft carrying the GSAT6 satellite into Geosynchronous Transfer Orbit (GTO).

    INSAT-2E is an Indian geostationary communications and weather satellite which is operated by the Indian Space Research Organisation as part of the Indian National Satellite System. It is positioned in geostationary orbit at a longitude of 83° East, from where it is used to provide communications services to Asia and Australia. It also carries two meteorological instruments; the Very High Resolution Radiometer, and a CCD camera capable of returning images with a resolution of one kilometre. INSAT-2E was launched by Arianespace, using an Ariane 42P carrier rocket flying from ELA-2 at the Guiana Space Centre in Kourou. The launch occurred at 22:03 GMT on 2 April, 1999.

    Barak is an Israeli surface-to-air missile (SAM) designed to be used as a ship-borne point-defense missile system against aircraft, anti-ship missiles, and UAVs. The missile of Barak SAM system is designed to replace or complement gun-based CIWS platforms, such as the Phalanx CIWS, with a more flexible and longer-range SAM. The missiles are mounted in an eight cell container (which requires little maintenance) and are launched straight up. The launcher of Barak SAM system utilizes a compact vertical launching system, with an 8-cell module weighing 1,700 kg. Fire control is provided by an equally compact C3I system that weighs 1,300 kg, which can either operate independently or in conjunction with other onboard sensors. The radar system of C3I provides 360 degree coverage and the missiles can take down an incoming missile as close as 500 meters away from the ship. Note : Recently, India & Israel jointly developed most advanced long range surface to air missile Barak-8 was successfully test fired off the Odisha cost. Reports suggest the missile has been increased to a maximum range of 90 km following “range upgrade discussions” between India and Israel during November 2014. Barak 8 was jointly developed by Israel Aerospace Industries (IAI), India’s Defence Research & Development Organization (DRDO), Israel’s Administration for the Development of Weapons and Technological Infrastructure, Elta Systems, Rafael and other companies. Bharat Dynamics Limited (BDL) produces the missiles.
