India's SARAL-Altika satellite to study rising sea level

-

With ocean scientists reporting a nine mm rise in sea levels in four years, India will launch an exclusive satellite later this year to study the changes in the environment.

The SARAL-Altika satellite will complement the current observations of the sea made by current satellites like Jason-2 of the French Space Agency and NASA.

“The SARAL-Altika to be launched by this year-end will have a high-resolution altimeter in the Ka-band,” Marc Pircher, Director of the Centre National d’Etudes Spatiales (CNES), the French space agency said on the sidelines of the 97th Indian Science Congress here.

He said the satellite would be useful in studying the sea state, light rainfall climatalogy, mean sea level and coastal altimetry.

Shailesh Nayak, Secretary, Ministry of Earth Sciences, said that SARAL-Altika would help ocean scientists gather accurate data on the rise in the sea level which could threaten the low lying and coastal areas of the country.

“SARAL-Altika will have a Ka-band altimeter which will measure the rise in the sea levels accurately than the current satellites,” he said.

SARAL-Altika, an Indo-French collaboration in the environment monitoring domain, will have two independent payloads – ARGOS-3 and Altika – whose objective would be to promote the study of environment from space.

The first batch of the indigenously built T-90 Bhishma tanks was on Monday (August 24) flagged off by Minister of State for Defence MM Pallam Raju at the rolling out ceremony held at the Heavy Vehicles Factory, Avadi, in Chennai. The T-90S tank incorporates many new technologies in terms of mobility, protection, fighting capabilities, safety and communication. The tank is equipped with 125mm smooth bore gun stabilised in Elevation and Azimuth, 12.7mm anti-craft machine gun and 7.62mm co-axial machine gun supported with high accuracy sighting systems and Automatic Loader ensuring high rate of fire. A significant feature of this tank is its capability to fire guided missile in addition to conventional ammunition using the same main gun barrel. The integrated fire control system consisting of the gunner’s sight, guided weapon system and ballistic computer facilitates accurate firing of conventional ammunitions as well as the guided missiles. The built in Explosive Reactive Arm

Second only to US IAF & Navy to get DRDO's CHAFF tech for protecting Aircrafts and Ships from enemy missile

-

The Indian Air Force and Navy have partnered with the Defence Research and Development Organisation to acquire the CHAFF technology, which protects warships from anti-ship missiles during combat. After the United States, India is now the second country to develop this capability, signalling a major Aatmanirbhar push in the field of defence. The development is significant because the Indian navy is investigating the sinking of the Russian missile cruiser Moskva and concentrating on how to protect our warships from anti-ship ballistic missiles such as the Chinese DF-21. What exactly is CHAFF? CHAFF is a critical defence technology that protects fighter planes and naval ships from enemy radar-guided missiles during wartime. The importance of this technology stems from the fact that a small amount of CHAFF material deployed in the air acts as a decoy to deflect enemy missiles, ensuring the safety of fighter planes and naval ships. This advanced CHAFF technology was developed by the DRDO to

India built N-sub in Kalpakkam under codename 'PRP'

-
The secrecy attached to the development of the indigenous nuclear submarine project is almost legendary. What’s little known is the extent to which the Indian N-establishment went to conceal the research not only from the public but also large sections of the scientific community within the Department of Atomic Energy (DAE). For almost nine years, most staff working at the Indira Gandhi Centre for Atomic Research (IGCAR) in Kalpakkam believed the Plutonium Recycle Project (PRP) in the complex was used only for that purpose, that is recycling plutonium. But with the launch of INS Arihant on July 25, top DAE officials have finally begun to lift the veil and reveal that they were actually building the core (nuclear reactor and propulsion systems) of the submarine as well as the land-based version of the hull of the indigenous vessel, which served as the technology demonstrator of the main vessel, within the PRP unit. For those in the know, even the term ‘PRP’ denoted the N-sub.
