UNMANNED SURFACE VEHICLES (USVs)

Why do you need Inertial Navigation Systems for Unmanned Surface Vehicles?

Inertial Navigation Systems (INS) are essential for Unmanned Surface Vehicles, providing continuous navigation and positioning in GPS-Denied maritime environments. Here’s why these systems are critical for USV operations:
  • GPS‑denied maritime zones – In littorals, ports, or contested waters where jamming or multipath interference is likely, INS offers continuous, reliable navigation.
  • Autonomous operation – INS enables USVs to carry out missions like patrol, survey, or data collection without constant signal correction.
  • Persistent positional data – Even during abrupt turns or in choppy seas, INS maintains velocity, position, and heading data.
  • Coordination & swarm behavior – For coordinated USV fleets, INS ensures tight formation control and mission alignment.
  • Search accuracy – In rescue or inspection missions, INS supports precise grid patterns and reduces overlap or missed areas.
  • Sea-state resilience – Drift-free INS empowers USVs to retain tracking accuracy amid waves and vessel motion.

Inertial Navigation Systems play a critical role in guiding Unmanned Surface Vehicles by delivering consistent, accurate positioning in conditions where GPS is limited or denied. These systems are especially valuable for ensuring mission success in open water, ports, or contested maritime zones.
