There are now solid-state accelerometers, literally you can buy a single IC chip off the shelf that is a solid-state accelerometer capable of generating data "instantly" for all three axes of motion. Among other things they are used to track for inertial navigation systems. I don't think they've replaced anything on the Polaris submarines, but they should be more than adequate for generating correction data on a fluxgate compass.
