Bharat Rakshak Forum Announcement

Hello Everyone,

A warm welcome back to the Bharat Rakshak Forum.

So this only buys you the drone? What about training, modifications to support Indian data-links, Indian SATCOM terminals etc, what about the sensor package and logistics? Any offsets involved? Taking a top line and dividing it by the projected number may work with the largely ignorant (on defense matters) MSM, but if you are discussing something in a forum that has a higher level of discourse then it is definitely not adding much imho

Obviously, the support cost is understood. But what I don't understand is that the cost of each drone and it's support cost is half and half(45+45m).

I don't understand why India would put 2 billion into this. Obviously, I do understand that finding out the ORBAT structure on the other side of border is important before war but wouldn't smaller hand throw drones be appropriate for the job?

Heron that crashed in China seems to have had its navigation controls jammed by the chinese.


Just curious..Is there a self destruct button for errant UAVs ? How is the data secured on the her on?

Two things can happen:

1) Datalink is jammed and UAV programming aborts mission and returns home

2) Drone guidance is fooled and it thinks it landed in source country but in fact it landed in enemy country (see capture). This was an old problem and is not there anymore (see ins navigation).

In first case, the enemy state has no choice but to shoot it down(if UAV was spotted). No need for self destruct in second case.

How is the data secured on the her on?

A pilot switches off communication link with ground control when he operates in stealth mode to avoid detection. This is for deep penetration. For short range (10-20km), modern UAVs use their own sign language(Datalink) called line of sight communication. ie., one craft is in sky in source country pointing it's antenna at the UAV in enemy country. Due to curvature of earth among other issues, operational range is limited. Satellite Line of sight is also available(to increase operational range) but it doesn't solve the jamming issue.

A 1-2ft hand launched drone doesn't use active navigation so jamming and detection is not an issue. It flies on pre-determined trajectory.

thank you. So to be fool proof there has to be some fail safe that will kick in if it detects it has been compromised in some degree., a level of AI should be embedded.

Chaiwala to Paanwala Rustom 2 /Tapas has done over 11 flights. Work is going on for automated takeoff and landing. Probably user flight qualification will be done by 2020
