Likened to an underwater GPS system, NASNet^® is the ideal subsea positioning and navigational solution. As a broadcast only system, its reliable positioning provides reduced vessel times for high-quality data updates throughout the water column to the sea floor, regardless of working depths.

• Accurate range measurements between the calibrated NASNet^® array and passive receivers on tracked objects
• NASNet® overcomes the limitations of conventional LBL systems
• Long range and high integrity communications using acoustic digital spread spectrum (ADS2) signalling
• Integrates with inertial navigation system (INS)
• Supports all operational requirements including dynamic position reference (DPR), remotely operated vehicle (ROV) and structure positioning
• Simple system installation including optional single lift and deployment capability
• Simultaneously position unlimited objects at fast update rates
• Reduces ongoing maintenance costs
