Sonardyne Mini-Ranger 2: Portable USBL Tracking & Communications

Survey-Grade Precision for Nearshore and Marine Robotics Operations

Product Overview

The Sonardyne Mini-Ranger 2 is a highly portable, sixth-generation (6G) Ultra-Short Baseline (USBL) system designed for users who need the performance of a deep-water system in a compact, nearshore-optimized package. It bridges the gap between the entry-level Micro-Ranger 2 and the full-ocean depth Ranger 2, offering a standard range of 995 meters (extendable to 4,000 meters).

Built on Sonardyne’s proven 6G® hardware and Wideband® 2 digital technology, the Mini-Ranger 2 is ideal for tracking divers, ROVs, AUVs, and towed instruments from small vessels of opportunity or Uncrewed Surface Vehicles (USVs). Its "plug-and-play" nature makes it the go-to choice for rapid mobilization in challenging acoustic environments.

Why Choose the Sonardyne Mini-Ranger 2?

• Compact & Mobile: The entire system—including the transceiver and interface hub—is designed to be easily transported and installed on vessels as small as a RHIB.
• High Update Rates: Capable of update rates up to 3 Hz, providing near-real-time situational awareness for high-speed tracking or robotic control.
• Exceptional Shallow Water Performance: The HPT 3000 transceiver is specifically optimized for tracking at high elevations and in noisy, shallow-water environments where multipath interference is common.
• Marine Robotics Ready: More than just a tracker, it acts as a two-way communication gateway, allowing you to command and control AUVs and exchange data with seafloor sensors.
