Dear,No doubt what you have said is true. But supersonic doesn't go over 400 Km range is it and there is no variation in it's altitude weather it is at Hi-Hi-Hi, or Hi-Lo-Hi it moves at a predetermined height like 100-50-100 meters or 100-100-100 meters not like 100-80-50-120-30 meters
Terrain hugging means different in super sonic and sub sonic.
And as the distance increases chances of introduction of INS drift errors began to show right ? You need to keep missile on Path or if you want to change path, that's where GPS signalling chips in.
Without Navigation maps, if a mountain comes in b/w missile flight path and missile flying at say 100 meters, It wouldn't have a clue to avoid that obstacle That's where Tercom comes in, A map mated to digital altimeter to know exactly at which places to fly at low height and at which places to fly at higher height and that's the concept of Tercom. You could not achieve dynamic altitude variations without TERCOM and that's the concept of Sub sonic missile, fly low, avoid obstacles in path reach target. Without Navigation maps mated with digital altimeter how could Cruise missile avoid obstacles ?
DSMAC is concept, it depends upon the user how he wants to implement. Weather to use co-relator or go with an active seeker or IIR seeker. There are no two opinions on this one
"The missile maintained an accuracy better than 10 meters throughout it's path and covered a
distance of more than 1000 km"
Can you explain to me what does this line mean from DRDO press release ?
I have to sleep now, but I will reply tomorrow.
thanks
