Underwater Vehicles

Why do you need inertial navigation system for Manned and Unmanned Underwater Vehicles?

Inertial Navigation Systems (INS) play a role in the navigation of underwater vehicles (UUVs) due to the unique challenges presented by the underwater environment. Here are a few key reasons why Inertial Navigation Systems are indispensable for vehicles;
  • Overcoming GPS Limitations Underwater - Underwater environments pose limitations on Global Positioning System (GPS) signals often causing them to be limited or completely blocked. Inertial Navigation Systems operate independently of signals providing a solution for navigation in scenarios where GPS is unavailable.
  • Enabling Autonomous Operations - Both manned and unmanned underwater vehicles frequently operate autonomously or semi autonomously. Inertial Navigation Systems empower these vehicles to navigate independently making decisions based on real-time navigation data.
  • Ensuring Continuous Navigation - Inertial Navigation Systems offer navigation capabilities consistently providing information about the vehicle's position, velocity and orientation. This capability is crucial for maintaining course control and ensuring that the vehicle reaches its intended destination accurately.
  • Facilitating Accurate Depth Control - Maintaining depth control is essential for operation of underwater vehicles. Inertial Navigation Systems contribute to depth control by delivering real-time data on the vehicles pitch, roll and heave parameters enabling adjustments to maintain the desired depth level.
  • Enhancing Mapping and Surveying Capabilities - By integrating with sensors, Inertial Navigation Systems contribute to mapping and surveying of underwater environments.

These reasons highlight why Inertial Navigation Systems are components in navigating through challenging conditions, for both manned and unmanned vehicles. This technology holds value in the fields of research, environmental monitoring and underwater exploration.

  • Long Duration Missions - Unmanned underwater vehicles often operate for periods of time and the use of navigation systems allows them to maintain positioning over long distances and durations without requiring frequent updates.
  • Navigation in Challenging Conditions - Underwater conditions can be quite demanding with factors like visibility, strong currents and complex underwater terrain. Inertial Navigation Systems significantly enhance a vehicle's ability to navigate accurately under circumstances.
  • Military Applications - In both unmanned operations, underwater vehicles play a crucial role in missions like reconnaissance, surveillance and mine countermeasures. The use of INS ensures the navigation accuracy for these operations.
  • Reduced Dependency on Surface Communication - By employing navigation systems, underwater vehicles become less reliant on surface communication. This is particularly important when maintaining communication becomes challenging due to periods of submersion.
  • Emergency Recovery - In situations where communication is lost or emergency scenarios arise Inertial Navigation Systems provide the vehicle with capabilities. This capability is vital for recovering the vehicle or accomplishing its mission objectives.

To put it simply, Inertial Navigation Systems are extremely important for underwater vehicles. They provide the ability for these vehicles to navigate autonomously and continuously in situations where traditional navigation aids such as GPS are restricted or not available. This technology plays a role in guaranteeing the precision, safety and overall success of missions and operations.
