Soldiers at Fort Bragg, North Carolina, test the new positioning technology being developed by Echo Ridge.

The military is developing a new battlefield tool that will help ground forces navigate hostile territory without the susceptibility of GPS platforms. Instead, warfighters will use radio frequency signals as a source of positioning information. To display navigational solutions on a map, the tool connects to a smartphone running the Air Force’s Android Tactical Assault Kit.

In conjunction with the Air Force Research Laboratory (AFRL), Sterling, Virginia-based Echo Ridge LLC is designing the technology to fit in a small, low-power package that can be carried by ground operators, according to Mark Smearcheck, an electronics engineer with the AFRL Sensors Directorate.

The KeyW Corp., Hanover, Maryland, has been awarded a $23,924,180 cost-plus-fixed-fee contract for the Research to Advance Comprehensive Exploitation of Radio Frequency (RF) Research and Development (R&D) program. This contract provides for the R&D of RF exploitation technology with innovative algorithmic approaches for dynamic and flexible sensing, capable of leveraging all available information to maximize sensing and exploitation performance, to address concurrent detection, tracking, imaging, and classification/identification of targets within contested and challenging environments with singular and distributed sensing architectures.

This image captures the results of an experiment conducted at the U.S. Naval Research Laboratory in Washington, D.C., where scientists set up radio sensors around buildings to test whether they could locate a small transmitter by listening for its emissions. They located the transmitter, but they were less successful as the emissions got farther away. An algorithm under development could help locate an emitter with a network of inexpensive power sensors.

Advances in a plethora of military communication and situational awareness platforms have created unintended repercussions for the U.S. Navy, from the “forest of antennas” that can consume a ship’s deck to the debilitating effects of radio interference that clog airwaves and impede critical links to vessels, aircraft, drones and even satellites. Navy engineers are toiling on a handful of projects to ensure effective and secure communication links, which are so fundamental to military operations.
