There is a difference bw ramjet and ramjet rocket propulsion??
Yeah,ny question is why dont we use the Akash's propulsion technique in Astra that will increse its range.

Both are ramjet .
The difference in Ramjet rocket propulsion system is that the soild fuelled rocket motor fits inside the combustion chamber of Ramjet .
The solid fuel rocket motor when burned out forms the combustion chamber for the ramjet engine .
I have a doubt whether it's solid fuelled although some sources mentions so
How can a solid fuelled Ramjet engine work ??

Solid rocket booster is used as the first stage for ramjets(They cannot operate from standstill )

I guess ramjet is under development for Astra mk2...
But we get to hear about DRDOs 'Liquid Fuel Ramjet (LFRJ)' technology being developed for Supersonic LRSAM...

You are right .... I rechecked ... Solid fuelled Ramjets exist and are said to be even simpler to liquid fuelled ones .

Mini UAV Competitors for Indian Army Procurement
TAS Mini UAV on display at DefExpo 2014
The Indian Army plans to induct about 600 mini UAV systems comprising 1,400 to 1,600 UAVs with ISR and targeting data capabilities. The Army released a RFI against the requirement in the first quarter of 2011.
If you have access to IDP Sentinel you can read the QRs stipulated for the Mini UAVs here, and also peruse the full RFI.
Tata Advanced System (TAS) and Israel Aerospace Industries (IAI) are likely to emerge as top contenders for the contract.
TAS is a front runner having recently won a contract to supply Mini UAV'S to the Army's Northern Command. The company displayed its hand launched, field recovered mini UAV (above) at the DefExpo 2014.
IAI Mini Panther at Aero India 2011
IAI has been plugging its tilt rotor VTOL UAV, Mini Panther, at Aero India and DefExpo for years now.
The Mini Panther doesn't just take-off and land vertically, it does so automatically, reducing the likelihood of human error caused mishap. (The TAS UAV would suffer wear and tear during each field landing.)
The IAI UAV can carry a payload of 2-kg, has a operating range of 20-km, endurance of 2-hr and loiter speed of 40-k.

SAAB RBS15 Mk-3 Mobile Missile Coastal Battery (MMCB) Contender at DefExpo 2014
SAAB RBS-15 at DefExpo 2014
SAAB's RBS15 Mk-3 displayed at DefExpo 2014 is a strong contender for India's planned Mobile Missile Coastal Batteries (MMCB) procurement because of its land attack capability and multiple launch platform options.
The RBS15 has been around for 30 years and has been deployed by several countries on ships, coastal batteries and aircraft for targeting sea based threats. The RBS15 Mk-3 has the ability to also engage land targets, a requirement stipulated in the MMCB RFI released by Integrated Headquarters in October 2013.
The latest air-to-surface version of the missile - RBS15F ER - is capable of engaging sea based threats in open seas or littoral waters.
The RBS15 Mk-3 has a range of 200-km and carries a 200-kg blast and fragmentation warhead triggered by delayed impact (to ensure penetration) or proximity fuse. The sea skimming missile can be programmed to route through numerous vertical and horizontal way points, facilitating over the horizon targeting. It's capable of carrying out random maneuvering during its terminal phase.
The missile uses inertial and GPS navigation. It features a pre-launch programmable radar seeker with ECCM and target discrimination giving it a fire and forget ability.
The sea and land launched RBS15 Mk-3 variant of the missile weighs 670-kg and the air-launched RBS15F ER variant, 600-kg.

BEL, Textron's MOU to Pitch MicroObserver Unattended Ground Sensor (UGS) Systems to Indian Security Forces
Textron Systems MicroObserver Unattended Ground Sensor (UGS) System. Photo Courtesy Textron
BEL on February 6, 2014 signed a MoU with Textron Systems as a first step toward providing the Textron Systems MicroObserver Unattended Ground Sensor (UGS) system to Indian security agencies.
The system provides unattended, networked, seismic, acoustic and imaging surveillance using ruggedized components: long-term sensor node, tactical sensor node, gateway, IR camera, and operator terminal.
The MicroObserver system provides detection, classification and tracking of people and vehicles. The system can identify targets is possible using sensor-cued infrared imaging, utilizing proven target detection algorithms to capture a series of mini-video images.
Rather than showing just a single detection alarm, the MicroObserver UGS system provides actionable intelligence by displaying the position, direction and speed of personnel and vehicle threats, making it easier for security forces to locate, identify and intercept them.
Deployed MicroObserver systems automatically self-locates using embedded GPS and operate in a self-forming, self-healing network. Security forces can deploy the system in minutes under cover of darkness, limiting their own exposure.
Textron is plugging the system for use by Indian security forces through its tie up with BEL.

BEL to Manufacture CoMPASS for Rudra ALH WSI Helicopters
Rudra ALH WSI at Aero India 2013
Israel's Elbit Systems Intelligence and Electro-Optics - ELOP Ltd (ELOP), a subsidiary of Elbit Systems Limited, has placed an order on BEL for CoMPASS systems for HAL's Rudra, or ALH WSI helicopter.
BEL had earlier signed a Technical Collaboration Agreement with ELOP joint manufacturing and D-Level Maintenance of CoMPASS in India and established facilities for the same.
The contract was signed on February 7, 2014 during DefExpo 2014.
The Rudra is equipped with the CoMPASS, a day-and-night surveillance system that includes color TV daylight camera, 3rd Generation 3-5 µm Forward Looking Infrared (FLIR) sensor, Laser Target Designator and Range Finder (LTDRF) and automatic tracking capabilities, as well as command and control capabilities. CoMPASS features a wide variety of interfaces, enabling integration with various aircraft / helicopter systems, such as Mission Computer, fire control, radar, GPS, data downlink and helmet-mounted tracking systems. Its small dimensions, low weight, high level of stabilization and coverage angles make it an optimal choice for long-range, day-and-night surveillance, target tracking, fire control applications and search and rescue.
Rudra's armament includes a 20 mm French Nexter gun turret gun cued by the pilots helmet mounted sight, MBDA's Mistral air-to-air and air-to-ground short range missiles, and a Belgian 70mm rocket system. The gun can swing up, down and around.

Tata Power SED's Hybrid BIHO 30mm Gun & Missile Air Defense System at DefExpo 2014
A model of Tata Power SED's Hybrid BIHO 30mm Gun & Missile Air Defense System at DefExpo 2014
Tata Power SED is collaborating with South Korea's Doosan DST to produce a hybrid version of Doosan's 30mm BIHO Self Propelled anti-aircraft gun system. The hybrid system will field the existing twin 30mm guns as well as VSHORAD missiles and will be mounted on chassis of K-21 IFV manufactured by Doosan DST, but the hull and chassis of the IFV will be manufactured, using alternate material, based on Doosan TOT, at Tata's new manufacturing facility being set up on the outskirts of Bengaluru.
The system will have crew of four, combat weight of 26.5-t, max speed of 60-kph and a cruising range of 400-km. It will be able to negotiate a gradient of 60-deg and slide slope of 30-deg; and it will be a able to ford through 1.2-m of water.
It will be equipped with an XBand Pulse Doppler radar as well as electro optic sight for passive day (TV) and night (Thermal) tracking of targets from 0.1-km to 7-km.
The twin 30-mm will be able to fire 600 rds/min each to an effective range of 3-km. The missiles will have a max effective range of 7-km, max altitude of 3.5-km, max speed of Mach 2.1 and feature a HE warhead with impact and proximity fuse.
