It can survey a large body of water using acoustic navigation
and high-resolution imaging.
The same tomography/thermometry network of acoustic sources and receivers can also provide long-term passive acoustic listening, underwater acoustic navigation (performing a global positioning system [GPS] function underwater), and low bandwidth communications providing the navigation and timing required for under-ice operation of autonomous gliders, floats, and unmanned undersea vehicles (UUVs) in the Arctic (Fig.
Acoustic networks can improve observations of the water column beneath the ice directly, using tomographic/thermometry measurements, while simultaneously providing acoustic navigation and communications supporting autonomous vehicles.
The AITPs are currently equipped with 1560 Hz and 780 Hz sound sources to provide acoustic navigation of and communication with gliders and floats operating under ice.

Yi-Xian Qin, Director of the Orthopaedic Bioengineering Research Laboratory at Stony Brook University, has revealed that the new technology, called Scanning Confocal Acoustic Navigation
(SCAN), works by assessing multiple parameters of hard tissue like bone.
APOGEE was designed with critical acoustic navigation
and control systems that allow it to navigate to a homing beacon, latch itself to a wire suspended from a hole in the ice, and ultimately be recovered by scientists on an icebreaker or an ice camp.
Let go of the latch, and, using an acoustic navigation
system to guide its movements, travel around its survey area taking video snap shots and making a variety of measurements.
