There is a problem in selling drones to India. See, drones can carry bombs, which effectively makes them missiles. But they also have range of over 300 kms, which is banned under MTCR rules. IOW, India cannot buy drones because of MTCR restirctions :x .

We *might* see US do a 1-2-3 agreement for us in MTCR as well, :)

When India is developing stuff, everyone will queue up to see us their products.
India developing UAV similar to American Predator drone
http://economictimes.indiatimes.com/new ... 728979.cms
UAV Rustom-2 project is spread over 66 months, Director of Bangalore-based Aeronautical Development Establishment (ADE), a Defence Research and Development Organisation ( DRDO) laboratory, P S Krishnan, told PTI here.
Rustom-2 would have a wing-span of 21-odd metres and an endurance of 24-hours-plus, as against seven-odd metres and 12-15 hours of Rustom-1, which has already completed five flights. ADE is the nodal lab for these projects.
Rustom-2 would have new payloads such as synthetic aperture radar, maritime patrol radar and collision avoidance system, among others, he said.
Meanwhile, Rustom-1, the Medium Altitude Long Endurance Unmanned Aerial Vehicle (MALE - UAV), would be integrated with payloads by next month, Krishnan said.
"We have demonstrated all the flying characteristics of the Rustom more or less in the final form".

the only cash rich markets for the US to exploit for amortizing its projects are
- saudi barbaria
- UAE
- South Korea
- Japan
- Singapore (too small)
- Australia
- India
- Turkey (one of the new BRICs)

israel is a munna and never pays anything its covered under their yearly aid. the Euros buy things in small nos. other than India, the others are all 101% halal Munna's ... India is truly a special case.

Thales and Aerovisión present FRONTEX with an unmanned aerial vehicle for border control

The UAV Fulmar is a small-size model (3.1 metres) weighing only 19 kilos that can fly at a height of 3,000 metres and achieve 150 kilometres per hour, with an 8-hour flight range that would allow it to fly up to 800 kilometres without having to refuel.


The demonstration confirmed the ease of installation and flying of the UAV Fulmar, as it does not require a runway for takeoff and landing given that it is launched from a catapult and is recovered by means of an impact-absorbing net. Both elements are simple to install in a short time and in different places.

DRDO lab tests UAVs

In a significant boost to Indian capabilities in using unmanned aerial vehicles (UAV), the Aeronautical Development Establishment (ADE) — a laboratory under DRDO — conducted flight trials of micro and mini UAVs at Hoskote near Bangalore.

According a press release from the DRDO, three Micro Air Vehicles named Black Kite, Golden Hawk & Pushpak with sizes ranging from 300 to 450 mm with a maximum ‘all up’ weight of 300 gms to 500 gms have been flight demonstrated and these vehicles have an endurance of 30 minutes and carry a miniature daylight video camera as payload that relays the imagery of the gaming area to ground control during its flight. The video and telemetry range is about two kilometres.

These vehicles are designed and developed to meet requirements including countering low intensity conflicts, counter terrorism and for rescue operations during natural calamities. These small vehicles are capable of flying in full autonomous mode and transmitting live day and night video to the portable Ground Control Station (GCS) in real time. Two mini UAVs categorised under 2 Kg class vehicles with endurance of 1 hour were also demonstrated and these vehicles carry either a daylight camera or thermal/night vision camera (one at a time) as payload and thus have capability for both day and night surveillance.

To ask a question:

How many UAVs do the Indian armed forces have ?

62 Herons (12 Navy and 50 IAF) ?

100 Searchers

12 Nishants ?

That's as far I have been able to calculate.

Any input welcome.

Isn't the cost of Netra a little high ?
Each unit costs around Rs.15-20 lakh.

Will the cost decrease once mass production is achieved ?

In what would be a significant move once it comes through, the IAF is already in talks to have a separate cadre for the RPVs and is in the process of drafting a proposal to be sent to the Centre.

“Just like the fighter pilots, transport pilots and so on, this will be a role-specific cadre, so that the officers are trained for a specific role from the word go,” a senior official said.
The IAF, which already uses UAVs, is in the process of multiplying the forces. And DRDO’s Rustom and Lakshya-II are also expected to be inducted into the IAF.

Air Marshal Dhiraj Kukreja, Air Officer Commanding-in-Chief, Headquarters Training Command, Bangalore said: “...There are talks about sending a proposal for this. We currently discussing various options.”

Speaking to Deccan Herald over phone he said: “...It would be part of existing squadrons but said that the numbers might not to the same tune. Flying squadrons have about 12-15 aircraft.”

Indicating that the procurement/acquisition of the UAVs in the future will be based on very careful assement so as to balance between the manpower and the role of such vehicles, sources said that the number of UAVs however will not be as high as 12 or 15.
The IAF though, is already training its personnel for this specific role as the air force already has some UAVs in its fleet.

But Kukreja said: “At present we are diverting people who are medically incapable of being fighter piolts into this role but with the kind of advances the medical field is making, we will soon see the number of such people reduce. And that is where this proposal comes in handy.”

Thales enhances its maritime border surveillance offer

Thales has reinforced its coastal and maritime border surveillance offer thanks to the FULMAR maritime surveillance and identification UAV system from the Spanish firm Aerovisión.


Thales has bolstered its maritime surveillance systems offer with the addition of innovative surveillance and identification capacities, through the integration of the FULMAR long lasting medium-range UAV, a 100% European platform with a unique capability of landing at sea. Jointly developed in Spain by the teams of Thales and Aerovisión, the Thales solution considerably improves the operational capacities of the coastguards by enabling rapid and easy detection of new threats.

In this way, Thales is able to propose a complete and modular solution for coastal surveillance and intervention, built around a C2 system and incorporating multiple coastal sensor data (radar, electro-optical, sonar, Automatic Identification of Ship - AIS etc.), mobile surveillance, communication networks and mobile equipment with intervention capabilities (UAVs, patrol / interception craft, vehicles, etc.).

BAE demonstrates UAV recovery capability

BAE Systems has for the first time successfully demonstrated the ability for an unmanned aerial vehicle to recover to an airfield which is unfamiliar to its mission system.

The demonstration – conducted at West Sale in Victoria – was conducted by a Kingfisher 2 UAV, and also saw the vehicle successfully integrate into nearby RAAF East Sale’s busy air traffic services.

“Most autonomous landing technologies require a fair amount of specific detail about an alternate recovery airfield before the aircraft’s launched on its mission,” said BAE’s Airborne Systems Integration and Development’s general manager Brad Yelland. “We’ve shown that we can get the aircraft back safely when its mission system has almost no detail about an airfield but still has to land there.”


That, is a real breakthrough

Asian Debut for Hermes 900 UAV

Elbit Systems is displaying its largest platform of the Hermes family of UAS – Hermes 900.

Hermes 900 was designed as a derivative of the Hermes family of UAS, introducing significant savings and enhanced capabilities over existing platforms. With over 300,000 operational flight hours with Hermes 450 UAS, the new ‘900 inherits the reliable building blocks, ground support equipment, payloads and ground mission controls, while expanding the flight envelope and endurance to new levels.


Among the key capabilities offered by the new drone are longer endurance, flight altitude of 30,000 ft. and a large payload capacity (up to 350kg). Unlike many other UAS, the Hermes 900 is designed with a 2.5 meter long internal payload bay, capable of accommodating up to 250 kg and allowing quick modular payload installation and replacement. The spacious bay accommodates multiple payloads with more installed on four hard points under the wings. The UAS includes innovative avionics and electronic systems, a low noise engine, as well as solutions that can be offered for sense & avoid capabilities and safe integration of the UAS into the relevant air space.

The ‘900 employs the same ground control station, line of sight data link, various sensors and key ground support equipment elements as the Hermes 450. This enables seamless insertion of the new UAS into Hermes 450 units, enabling users to benefit from reduced logistics and operational cost.

A typical sensor suite includes the baseline EO payload DCoMPASS, or Stand off EO/IR/Laser system such as the AMPS from ElOp. Different area surveillance missions can be performed in parallel to the EO payloads; these include various radar systems such as the SAR/GMTI and Maritime Search Radars. Three new mission specific sensor packages are being introduced for the drone – the electro optic mapping and survey area scanning systems (LASSO), hyperspectral payload and wide area persistent stare system.

The sheer size of the drone enables the deployment of other sensors – hence, the SIGINT payloads include the Skyfix COMINT/DF and Skyfix-G COMINT GSM systems. Electronic attack configurations may include the SKYJAM communication jamming system and AES 210 V/V2 ESM (ELINT) systems.

Hermes 900 uses an integral satellite communication data link enabling operations beyond line of sight and in mountainous areas, where line-of-sight restricts non SATCOM UAS from descending to lower altitude. In addition, the UAS can takeoff from a launch and recovery site in theater and be controlled from a mission station positioned remotely and conveniently in the user’s home facilities thousands of miles away. In order to implement this capability, Elbit Systems uses a cutting edge SATCOM system that combines highly advanced technologies, increasing bandwidth efficiency and assuring maximum cost effectiveness for its customers.

x-posts from special forces thread -

------------------------------

How accurate are the coordinates that can be acquired by UAVs? Good enough to feed into precision guided artillery?

------------------------------

The fundamental issue is that of determining locations of targets in real time, and rapidly delivering ordinance accurately to those locations.

What is needed is UAVs fitted with SARs, thermal imaging cameras etc which can accurately acquire targets within an accuracy of a couple of meters say, and the ability to send PGMs there.

Any ideas on what is possible in principle, and what DRDO might be able to deliver.

--------------------------------

While GPS can be accurate to < 1 meter resolution, that capability is only available to the US military. Everyone else has to make do with a degraded signal which is accurate to around 20 meters resolution or so. The only way to get around this is to create your own GPS system, which some countries are attempting to do, such as the EU's Galileo system and India's IRNSS program. However, these systems are still under development and until they are brought online, everyone has to rely on the GPS system from the US.


Right ... but IMHO the harder issue is coordinates acquisition. You can put a gimballed camera on a UAV. You know the location of the UAV with GPS, and you can get roll and pitch values with level sensors. Using a series of GPS measurements can give you the approx bearing, but then if there is a wind, the UAV may not be pointing in the direction of travel. A compass would also give approx data.

Perhaps better to use 2 UAVs and get the target coordinates by triangulation. First get approx location using one UAV, then get both UAVs to take simultaneous snaps of the site. Then a human operator takes the two images and manually locates the target on each. You have the GPS readings of each UAV at the instant of the snaps. You would also have a non-real time satellite image of the area, with coordinates grid.

Of course one or both UAVs can be replaced by a soldier on the ground, but you may often not have somebody on the ground when a target is first spotted in a remote area.

The question is what accuracy you can get by using all this data.

'First flight of UAV Rustom-2 scheduled in Feb, 2014'

The first flight test of indigenously developed UAV Rustom-2, set to be used solely for defence purposes, would take place in February 2014, a top Aeronautical Development Establishment official said today.

"Designing of Rustom-2 has been completed, purchase orders have been placed and we are on schedule to fly for the first time in February 2014," ADE Director P S Krishnan told reporters.

He said the entire project of making 10 Rustom-2 UAVs and spare vehicles at a cost of Rs 1,540 crore would be completed by August 2017.

Indigenous technology would enable ADE save about 40 per cent cost, he said, adding that all parts, except for cameras and sensors, have been developed in the country.

Weighing 1.8 tonnes, Rustom-2 would have a capacity payload of 350 kg, a wing span of 21-odd meters and an endurance of above 24 hours, he said.

Rustom-2 is in the league of US 'Predator' drones due to its advanced capabilities and additional payloads, he said.

"Rustom UAVs could be deployed for military missions like reconnaissance and surveillance, target acquisition, target designation, communications relay, battle damage assessment and signal intelligence," Krishnan said.

In future, India would also develop Unmanned Combat Aerial Vehicles (UCAVs) and solar drones, he said.

Rustom-2, designed and developed by ADE, a DRDO laboratory, is comparable to top drones in the world, he said.

The second edition of the two-day international Conference on Autonomous Unmanned Vehicles would get underway here from February 24, Krishnan said.

A UAV of the nature of Rustom -2 should cost around US$ 5-7 million or so. Assuming Rustom-2 is even cheaper, say US$ 4 to 6 million USD, I guess that 10 Rustom UAVs mean ten "units" of Rustom UAV which would mean around 10x5=50 flying aircrafts. That would mean price of around US$ 6 million per UAV including development cost.

China can have him, along with the amazing "ex-USSR super scientists" that they were alleged to host.

Whatever hollywood/bond movies try to convince us about the awesomeness of "nerds of Americas", we do not want "independent consultants" in a cutting edge area like UAVs skulking around Old Airport Road. In these sensitive areas, Gerard Bull was an exception and even he had controls put on him by his native country's alliances.

We are not yet there, where dissident thinkers and researchers consider Indian academia as a cozy refuge and anyone else claiming otherwise needs to be vetted.

As George J-saar rightly says, we want more of these sort of awesome people.

Interesting little nuggets of information about drones:
10 Things You Didn't Know About Drones
As of July 2010, the Air Force had identified 79 drone accidents costing at least $1 million each. The primary reasons for the crashes: bad weather, loss or disruption of communications links, and "human error factors," according to the Air Force. As Lt. Gen. David Deptula, former Air Force deputy chief of staff for intelligence, has noted with refreshing honesty, "Some of the [drones] that we have today, you put in a high-threat environment, and they'll start falling from the sky like rain."

Most unmanned aircraft flown by the U.S. military require not just a ground-based "pilot," but also a platoon of surveillance analysts (approximately 19 per drone), sensor operators, and a maintenance crew. Some 168 people are required to keep a Predator drone aloft -- and 180 for its larger cousin, the Reaper -- compared with roughly 100 people for an F-16 fighter jet. To keep up with the demand, the Air Force has trained more drone operators than pilots for the past two years. The upside is that, according to the Congressional Budget Office, drones "are usually less expensive than manned aircraft" ($15 million for a Global Hawk versus about $55 million for a new F-16), though costly sensors and excessive crashes can negate the difference.

Robot bee assembles in pop-up origami trick

Army-funded researchers at the Harvard Microrobotics Laboratory are popping out Harvard Monolithic Bees ("Mobees") from multi-layered, laser-cut blocks about the size of a quarter.

Inspired by pop-up books, the manufacturing process could allow for rapid production of dozens of flying robots and other electromechanical devices. The research is being published in the March edition of the Journal of Micromechanics and Microengineering.

In the RoboBees project, Pratheev Sreetharan and colleagues want to build bee-size robots that can fly and act autonomously as a colony. Until recently, it used a painstaking manual assembly method.

The prototype sheets consist of 18 layers of carbon fiber, titanium, brass, ceramic, adhesive sheets, and the plastic film Kapton. As seen in the vid below, the bee snaps together as it pops out of the laminate.


Colony of UAVs - sounds like the "swarm" from Prey (Michael Crighton). Yet another Indian steering a project at Harward.

This is what wiki states

The Global Hawk costs about US$35 million to procure each aircraft.[3] With development costs included, the unit cost rises to US$218 million


It also mentions the FY2012 flyaway cost as $105 mil.

Northrop Grumman BAMS Unmanned Aircraft System Program Achieves Two Major Milestones

"The MFAS sensor is the first radar system to provide full 360-degree persistent coverage of both open oceans and littoral regions from extremely long ranges," said Paul "Buz" Kalafos, vice president of Surveillance Systems. "The MFAS radar sensor will set the standard in maritime surveillance."

The MFAS sensor operates with a rotating sensor that incorporates electronic scanning and provides mode agility to switch between various surveillance methods. These include maritime-surface-search (MSS) mode for tracking maritime targets and inverse-synthetic-aperture radar (ISAR) mode for classifying ships. Image-while-scan capability is used to interleave very short duration ISAR functions (ISAR snapshot and high- range resolution) during MSS scans. Two synthetic aperture radar (SAR) modes are used for ground searches; spot SAR for images of the ground and stationary targets and strip SAR for images along a fixed line.

Once targets are detected by MFAS, the data is sent to ground station units in the form of tracks, single frame snap shots, as well as high resolution snapshots while still maintaining 360 degree coverage.


No concrete numbers :evil:
