Size and energy consumption would rule out the highest accuracy type of mechanical inertial guidance systems used on subs. MEMS type inertial sensors would be more likely on UUV's, but with reduced accuracy due to drift over long periods of operation.
DARPA is investigating an acoustic underwater equivalent to GPS. A constellation of long range transponders deployed on the ocean bottom to provide triangulation similar to GPS satellites.On Sun, Dec 18, 2016 at 7:43 AM, Robert VanderPol II <NoReply_RobertVanderPolII@fer3.com> wrote:
Doubt they would put the good stuff on something like that.
First would be risk of loss such as occured.
Second, money, SEGs are intended to be cheap, any INS would be off the shelf.
