The Sublocus underwater inertial navigation system by Advanced Navigation features high-accuracy north-seeking fiber-optic gyroscopes and accelerometers with a GPS receiver and pressure depth sensor, fused to deliver positional accuracy of 0.08 percent of distance traveled. The system also provides highly accurate roll, pitch, heading, heave, depth, and altitude.

Sublocus is also available with an integrated RDI Workhorse Navigator DVL for combined acoustic and inertial navigation in the one product. Both models are supplied with a subsea GPS antenna and are rated to 3,000 meters depth.
