Undersea Warfare Tracking/Training Range (UTR)

Working in partnership with the U.S. and international navies, L3Harris has constructed the largest fixed UTRs installed over the last five decades. We can accommodate and install hundreds of specialized nodes (fixed and portable) engineered to meet the specific needs of our customers. Our products have demonstrated successful system provision with a more than 20-year operational life in a variety of environments and ocean depths. The team at L3Harris has worldwide program, design, marine installation and operations experience

Supporting Undersea Defense

Undersea Warfare Test and Training Ranges

Undersea test and training range provider for 5-eyes navies and space telemetry systems
Real-time 3D tracking and playback of red-blue mission exercise, acoustic measurements of underwater weapon system and ballistic missile defense and launch vehicle missile tracking
Bi-directional and modular communications across wide-band acoustic channels
Acoustic test ranges for static and dynamic characterization
Nuclear explosion detection sensors in support of United Nations nuclear test ban treaty

Fixed Ranges

Fixed ranges are permanently installed/ fixed in a planned location. The range sensors cover a set geographic area of the ocean and are connected to a shore operational center by subsea cables.
Demonstrated more than 20-year life
Bi-directional nodes allows voice and telemetry communications
3D location of multiple assets in real-time
Full ocean depth
Uses cable from all major suppliers
Expandable and flexible
Cable ship or vessel of opportunity installation

Portable Ranges

Portable ranges typically consist of battery operated, bottom-moored beacons. These beacons are temporarily installed in a location for a finite operation life of a few weeks to a few months, limited mainly by battery life.
Easily transported, readily deployed and recovered (re-usable)
Scalable
In-situ testing and training
Intelligent transponder
MK-84 based ping processing
Employs digital spread spectrum signaling
Tracks multiple targets
Real-time operator feedback
Operates for extended durations
