I meant just in context of our cruise missile application. Not that many Gs as in rockets, neither its blind like Subs, its augmented with other inputs from tercom/DSMAC.Sure there are. But this is a vague description. What primarily governs the quality of your INS is the noise in your sensors, which determines the drift per time in your INS. A military grade MEMS IMU may be good enough so an INS based on it can give a position that only drifts 100m in an hour. But that would be terrible for lets say a submarine. MEMS just means on a chip. So yes there are options but it really depends on your application. You also need to. consider your loads because that lets you filter things. Submarines can use aggressive filtering because they don't experience many Gs. A tube launched mlrs experiences many Gs so it can't rely on filtering that much. Just one aspect of INS. I don't want to turn this thread into INS. INS is a field.
