QinetiQ North America (QNA) has successfully demonstrated full-duplex underwater acoustic data communications using its new Dolphin technology, the company announced on 22 August.
The demonstration was part of the Advanced Navy Technology Exercise held in Panama City, Florida, in mid-August.
Dolphin, developed in partnership with Optimal Systems Laboratory, uses cancellation technology that enables simultaneous transmit and receive acoustic communications. This is a key capability in the development of extensive undersea data and communication wireless networks, and a potential problem-solver for navy and commercial customers.
Dolphin technology enables self-forming acoustic underwater networks to operate similarly to wireless land networks with nodes in motion.
Other benefits include frequency independence, allowing Dolphin communications to be configurable on most systems and platforms, such as unmanned underwater vehicles, submarines and ships; and extremely low power communications.
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
DARPA’s Mission-Integrated Network Control (MINC) programme was set up to develop an autonomous tactical network and enable critical data flow in contested environments.
Why space is an essential part of modern military capabilities
Defence-secure mixed reality headsets can save hours, or even weeks, of travel time to fix defunct equipment or get subject experts effectively “on-site” where they are needed.
The Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) counter-improvised explosive device (C-IED) and Drone Restricted Access Using Known Electromagnetic Warfare (DRAKE) counter-UAS (CUAS) systems are mounted and dismounted RF jammers.
Adarga’s Vantage information analysis tool is in service with the UK MoD and individual UK forces. It builds on the company’s Knowledge Platform which processes, organises and analyses open source material, as well as information held by the user’s military, security and intelligence services.
