Ranger 2 USBL is a versatile underwater positioning, tracking, and telemetry system developed for subsea survey, offshore construction, defence, and autonomous vehicle operations. Designed to track, command, and position subsea assets in any water depth and from virtually any vessel type, the system supports simultaneous tracking of ROVs, AUVs, towfish, seabed sensors, and multiple underwater targets during complex offshore missions. Combining Sonardyne’s 6G acoustic hardware platform with Wideband 2 digital signal technology, Ranger 2 delivers highly stable and repeatable acoustic positioning performance for subsea navigation, vessel dynamic positioning, and robotic operations.
The system supports a broad range of operational configurations through modular hardware and expandable software packs, enabling users to tailor functionality for dynamic positioning, acoustically aided inertial navigation, autonomous vehicle command and control, and coordinated multi-vehicle missions. Integrated telemetry capability enables robust bidirectional communications with subsea assets and long-endurance seabed sensors, while compatibility with industry-standard dynamic positioning systems supports offshore drilling, construction, survey, and research operations. Ranger 2 can also be configured for USV deployment, temporary vessel installation, and ultra-deepwater operations using dedicated High Performance Transceiver variants and pre-calibrated Gyro USBL systems.
Designed for scalability and demanding underwater environments, Ranger 2 supports simultaneous tracking of up to 99 targets with tracking ranges extending beyond 11,000 metres in Low Medium Frequency (LMF) configurations. The system delivers positioning accuracy down to 0.04% of slant range when fully optimised and supports acoustically aided inertial navigation workflows for enhanced subsea positioning reliability. Sonardyne Messaging Service capability enables underwater data exchange at rates up to 9,000 bps, supporting coordinated AUV operations, seabed sensor networks, and complex multi-robot underwater missions.
