A heavy truck stands next to an artillery gun getting ready to fire at enemy posts. An imported Doppler-based dome antenna communicates with a weather station 15 km above the earth. The air drift and temperature likely to affect the trajectory of the shell is recorded by the floating weather station and relayed to the truck. The data is used to position the gun before firing.

This battlefield situation has been made a lot easier by the students of IIT Bombay.

They have developed an indigenous system that could soon replace the imported system and do away with the bulky truck to reduce the entire set-up to the size of about two laptops, cutting the cost, and the space needed.

The system, developed under as an Army Technology Board (ATB) project was displayed at the College of Military Engineering (CME) on Wednesday.

Developed by a team of six IITians in 18 months, the prototype was tested on March 8 at Deolali. A few more tests are to be carried out.

“The weather station is sent about 15 km above the earth with a balloon. It records weather parameters every second. This data is fed to the fire control system of the gun. The Indian Army has been using the system developed by a Finland company, but we have developed the system using off-the shelf components. This has helped us do away with the bulky truck which the original equipment incorporates,” said Kavi Arya, associate professor, Department of Computer Science and Engineering, IIT-B.

As part of the ATB, technologies required by the Army are outsourced to various institutions such as IITs and their development is funded by the Army.

Explaining the IIT-B project, an Army official said, “When an artillery shell is fired, the shell attains a vertical height during its trajectory. While the Air OP helps finalise the location of where the shell hits, the met station analyses the factors that can act upon it during the trajectory.”

Prashant Rupapara, an MTech student at IITB, said, “The Finland equipment uses a Doppler-based receiver block besides other components, whereas we have used GPS-based technology. We have integrated this with portable computers to make the whole set-up compact. We have thus achieved technological independence as well as cost effectiveness.”

Great news :tup:
But not sure a GPS based system can be useful still we have our own GPS up and running.
Nevertheless it's good thing that such projects are allotted.

As always .......:tup:

Indians are proud of IIT .

Its a good effort but what about other parameters. The weaknesses in this system will be exploited, so they have to be countered. But I have faith in IITians solving it quickly and effectively. Further proof, our govt is corrupt.

Good Development.
IITs should focus on also turbofan engines and areas in which are lagging.

Great news! I did t even know these Army Technology Board (ATB) projects existed! This is certainly very promising!

They simply reverse-engineered the guidance system from Finland, at least what they could. Don't expect them to invent anything breakthrough. They need something in front to copy from.

Kudos to IITians, we are proud of you guys, just don't leave India ,be our front running workhorse.I know poor quality of labs and less pay in India sucks but still it's your motherland work for her.

Finland ?? Elaborate.

The balloon floats 45,000 ft high? How about the drift? It could be miles away within a couple of minutes rendering it useless for transmitting localised atmospheric conditions between the gun and target area. And these balloons at that altitude can't be tethered!

Or am I missing something here? :undecided:

There won't be noticeable drift as air is very-very thin up there.
Yep you are missing Troposphere which contains 80% of our atmosphere but extends roughly till 15 km.All natural phenomenan like rain,storm,cyclone happens below 10-11 km altitude only.

The fact is that wind velocity is typically two to three times as great at 30,000 feet, in some cases even at 15,000 feet, as it is at 100 feet above ground. This means a factor of eight to twenty-seven as great for these high altitude winds, reduced only by the lesser air density factors at those altitudes.

Near the surface, the wind speed increases logarithmically with height (up to 3000 feet). Typical values of wind speed are as follows:

5 metre/second(m/s) at 10,000 feet, 10 m/s at 20,000 feet and 15 to 20 m/s at 40,000 feet. So at 45,000 ft wind speeds could range from 20m/s to 30m/sec, which means more than 100km/h!

Read the article. Both systems ard different.
