Responding to my earlier blog on the advanced chip-embedded guidance system successfuly tested on Agni-V, an expert at the cutting edge of these technologies emailed me the following. It will flesh out the understanding of interested readers so I’m copying it here:
“With regards to your latest article, the “fly-by-wire” concept in the A-5 comes from digitally connected multi-channel communications within its body for the control system, thereby reducing a lot of the cabling that would have otherwise gone into these missiles. This serves to reduce the risk of failure in the missile system and increases dependability.
“With regards to the embedding of the guidance system on chip (SOC), which enables the A-5 to possess superior accuracy, there is indeed an on-board computer on the A-5, which is more powerful than any used in previous vehicles. However, previous computers had severe weight, space, and cooling constraints. The guidance SOC based computers that weigh just 200 grams and possess around 7-10 times greater processing power than their predecessors. The embedded guidance SOC concept requires very little power, imposes much less space constraints, requires far less cooling, and, also very importantly, is not only more reliable and efficient, but also allows for far greater flexibility when choosing the warhead configuration.”
