shows that DRDO has carried out tests on the radar. Already tested on airborne platform for range etc. If i am not mistaken they have put that platform on 100 ft near airport to track the aircrafts etc. Looks like things are serious from the start.

The white one would be a DRDO made model of the same aircraft while the grey one is perhaps the Brazilian made model which is more accurate.

Isn`t this was possible that after fligth testing was done drdo could have taken all radars , antennas to brazil itself and then tested it on a single plane module so that any shortcomings could have been know instead of now waiting till mid 2012.

also why india is getting aircrafts in mid 2012 when they are ready

They will flight certify the plane, this processes will complete and certificate is issued for flight safty, then it will be taken to India where all the dummies equipment will be removed and real one will be installed then again processes of testing of radar and certification will start in India.

antennas to brazil itself and then tested it on a single plane module so that any shortcomings could have been know instead of now waiting till mid 2012.
it was flight tested by DRDO.

All the test facilities are in India, not in Brazil.

The aircraft is not ready until tests are complete and the aircraft is certified. India will receive them only after that. Actual integration and tests are yet to happen. Induction date is 2015-16.

Embraer flies Indias prying plane in Brazil

BANGALORE: India's dream of having a plane embedded with home-grown prying technologies finally inched closer to reality when the modified Embraer-built Airborne Early Warning and Control System (AEW&CS) took off on its maiden flight from the Sao Jose dos Campos flight test facilities in Brazil on December 6.

As reported recently, the systems for the EMB-145I aircraft is being developed by Bangalore-based Centre for Air Borne Systems (CABS), a Defence Research and Development Organisation (DRDO) facility.

The first aircraft will arrive in Bangalore early June for CABS' integration and flight trials will be executed by test pilots from the Indian Air Force's (IAF) Aircraft Systems Testing Establishment (ASTE).

"The first flight concludes another important phase in this programme and starts the flight test campaign. We are moving towards the delivery of the first aircraft during the first half 2012," says Eduardo Bonini Santos Pinto, senior vice-president (Operations), Embraer Defence and Security. The EMB-145I is a member of Embraer's Intelligence, Surveillance and Reconnaissance (ISR) family of aircraft and systems, modelled on ERJ 145, one of the most successful regional jet platforms in the world, with more than 1,100 units delivered and 1,918 million hours flown.

The aircraft was piloted by Embraer pilot and co-piloted by Gp Capt N Tiwari, chief test pilot, ASTE.
"The aircraft took off smoothly and flew for more than an hour without any hiccups and followed the simulated prediction closely. This critical milestone will put India in the elite class of countries, which have developed similar systems," G Elangovan, DRDO chief controller (Avionics) told Express from Brazil.

We are buying the same type of equipment from a variety of sources.

It will ensure that sanctions, if ever applied to India, will not hurt India.

However, maintenance will become a problem since each type will required specialised people and the inventory will multiply.

DRDO seeks nod for domestic AWACS - Indian Express

Buoyed by the success of its indigenous eye-in-the-sky last December, the Defence Research & Development Organisation (DRDO) has pushed for a homemade version of the advanced Airborne Warning & Control System (AWACS) that can peer deep into enemy territory from higher altitudes.

Days before testing the maiden flight of its Airborne Early Warning & Control system in Brazil, the DRDO shot off a proposal to the Defence Ministry seeking Rs 850 crore to "design and develop AWACS for the IAF".

The DRDO's proposal does not identify a technology partner but keeps open the option of taking on consultants as and when required. The aim is to develop long-range radars with onboard command, control and communications for both tactical and air defence forces from higher altitudes, says the proposal sent on November 21.

The AWACS is extremely useful for India in large conflicts as it surveys a wider expanse of airspace and coastlines, and can monitor large number of aircraft and warships from a greater height than the AEWCs. Moreover, it can provide a 360-degree coverage of aircraft movement and troop build-up nearly 400 km inside neighbouring terrains compared to normal 250 km (375 km extended) detection with a 240-degree vision of AEWCs.

The DRDO proposal highlights this ability of AWACS to track multiple targets through large distances, said sources.

So far, India has got three Phalcon AWACS, the last of which was delivered in mid-2011, from Israel's Elta. A major follow-on contract has been rumored since April 2008 but the contract is yet to be signed.

Armed with more than double the number of control operator stations, AWACS can trap more electronic intelligence and communications intercepts from air as well as maritime and key border stations.

The Rs 1,800-crore AEWC development programme, approved by the Cabinet Committee on Security in October 2004, was "a major milestone" towards realising the dream of indigenous AEWC to put India into a select club of countries.

Indian eye in the sky

SOURCE: FRONTLINE

A MODEL on a table of a Brazilian Embraer aircraft with an "antenna" mounted on its fuselage caught the eye as we entered a hall in the System Test and Integration Rig (STIR) unit at the Centre for Airborne Systems (CABS) in Bangalore. Inside, women software specialists were busy in front of computer screens. A few feet away, a life-size model of the fuselage of the Embraer EMB-145 aircraft had been modified into five operator work stations (OWS) where Indian Air Force (IAF) officers were simulating combat situations on computer screens.

"In an air battle, it is the pilot-controller coordination and trust that will win the battle. This software is one of its kind and has been developed by the CABS," said S. Christopher, Director, CABS, which is a unit of the Defence Research and Development Organisation (DRDO). He has been at the helm of affairs since January 1, 2007.

Elsewhere inside the "aircraft" was an Airborne Early Warning and Control (AEW&C) system simulator. "You can simulate any kind of aircraft, radars, and emitters in the form of radars, which can be airborne or ground-based," said Reena Sharma, scientist, CABS. In OWS-3 is the electronics support measures (ESM) system, which provides the bearing and location of hostile emitters and analyses their characteristics. The communication support measures (CSM) intercepts communication signals and analyses them. The Mission Systems Controller (MSC), the heart of the AEW&C system, integrates the data from all the sensors and facilitates the airborne surveillance operations. All the five OWSs were developed in-house by CABS scientist Rekha Sinha and her team. On December 6, 2011, an Embraer EMB-145 fitted with the Indian AEW&C system made its maiden flight at Sao Jose dos Campos at Sao Paulo in Brazil. It had about 1,000 mission system components developed by the CABS, including the critical Active Electronic Scanning Array (AESA) developed by the Electronics and Radar Development Establishment (LRDE), Bangalore, a DRDO laboratory. While the antenna called Active Antenna Array Unit (AAAU) is made by CABS, the AESA radar, which is the processor part of the AAAU, is made by the LRDE.

"The flight is a major milestone towards realising the dream of developing an AEW&C system indigenously, which will put India in a select club of countries," said V.K. Saraswat, DRDO Director General and Scientific Adviser to the Defence Minister.

While this aircraft will now undergo a full certification process over the next two years, India will receive two more Embraer aircraft by the middle of next year to be integrated with the AEW&C System.

The Indian AESA radar is the primary sensor for the indigenous AEW & C. The radar can look 240 degrees within a short time and has a range of 350 km; it can track more than 500 targets simultaneously.

The DRDO is spearheading the indigenous AEW&C programme with the CABS as the nodal agency. The latter is executing it in association with DRDO laboratories such as the LRDE; the Defence Avionics Research Establishment (DARE), Bangalore; the Defence Electronics Research Laboratory (DLRL), Hyderabad; and the Defence Electronics Application Laboratory (DEAL), Dehradun. Each of these laboratories is developing subsystems for the AEW&C programme.

The IAF has stationed an Air Force Project Team at the CABS to interact with the in-house team and convey the IAF's requirements. Air Commodore A.I. Mehta is the Project Director of the team.

The Brazilian Embraer aircraft EMB-145 was chosen because Brazil, Mexico and Greece had based their AEW&C systems on this aircraft. The DRDO was tasked with the mission.

The primary radar mounted on the Embraer aircraft is the AESA radar. The secondary surveillance sensor is the Identification of Friend or Foe (IFF) system. Two radiating planar arrays assembled back-to-back and mounted on the fuselage in an AAAU will provide 120 degrees coverage on either side of the AAAU. "The important modes of operation of the system are surface surveillance and air surveillance," Christopher said.

SOURCE: CABS, Bangalore


The IFF system has been developed entirely by the CABS. Christopher said, "The IFF determines whether the target determined the primary radar is a friend or foe. The interrogator emits a message querying the target in a particular sector. Replies from the target are automatically associated with the primary radar detections. This information is then used by the AEW&C system to identify friendly and unfriendly aircraft in the area and deal with them appropriately."

The Defence Acquisition Council has given approval for the indigenous development of 2,700 IFF systems and the Services want a single-box solution in the IFF system. The government has the option of buying the remaining 500 IFF systems in the global market.

It was a challenge for the CABS to integrate the AEW&C system components in the Embraer transport aircraft. While the aircraft's payload capacity was four tonnes, the AAAU alone weighed 1.5 tonnes. Besides, there were five OWSs with electronic systems inside, crew seats, special protection suites, and so on.

The AAAU had to be mounted on the fuselage without affecting the aircraft's structure and stability. If the aircraft were to crash, the AAAU should not get detached. The attachment had to be capable of bearing nine times the weight of the AAAU, that is, 13.5 tonnes, said Christopher. The attachment is done with only four bolts, which should be able to carry all the weight. Each bolt, made of titanium, has a diameter of one inch.



K. MURALI KUMAR

DR S. CHRISTOPHER, Director, CABS.


There are two levels of operation here. In the first, the aircraft is modified in Brazil and the DRDO sent all the components, including the antenna, the AAAU with dummy electronics, and so on for integration with the aircraft. M/s Embraer Engineers mounted them on the aircraft and configured it for the flight. Embraer's engineers also received the air-worthy certification for the aircraft from the Agencia Nacional de Aviacao Civil, the Brazilian agency responsible for overseeing the safety of civil aviation in that country.

In the second level, when the three aircraft with the Indian AEW&C systems are delivered in India after flight trials in Brazil, the remaining mission systems will be integrated inside the cabin and the IAF will do the flight trials again. The CABS will be responsible for having the AEW & C system certified for mission functions and flight safety in association with the IAF and the Centre for Military Airworthiness and Certification (CEMILAC), Bangalore.

Massive facilities that the CABS has built on its premises include an anechoic chamber, a lightning test facility, and highly accelerated life testing (HALT) and highly accelerated stress screening (HASS) facilities. The anechoic chamber is a huge shielded facility, 35x15x18 metres. The AESA radar is tested here.

In the lightning test facility, artificial lightning of four million volts is created to test the effect of lightning on aircraft and ensure that the electronics inside are not affected. The AAAU underwent qualification here. S.K. Venkatesh, scientist, CABS, is the architect of the facility. In the HALT and HASS facilities, different components are "hammered" or subjected to freezing or scorching temperatures to ensure they are robust.

350km range, phew. How much work will be needed to move in to next level now, I mean towards all round coverage. As they are looking for new platform, Once the platform is selected, I think it will be easy going after that. Or I am mistaken

ZZZ. The journo has confused the terms. AWACS was the old name for AEW&C. People still use the term AWACS because it is easier to say and type.

350km for an AEW&CS seems a bit short for today. DRDO better work on a 500km range version if they want to be serious about it.

The IL-76 is a huge aircraft. IAF might have need for smaller AEW&CS platforms too, which can operate from smaller airbases. The IN will probably love a smaller platform too.
