AI Overview

Custom integrated navigation systems combine

Inertial Navigation Systems (INS)—using accelerometers and gyroscopes—with GNSS , RTK , and AI-based algorithms to deliver centimeter-level positioning accuracy. These systems, such as NAVION® and Exail's Rovins 9-DVL , ensure reliable, continuous tracking in GNSS-denied environments like urban canyons, heavy foliage, or subsea, using dead reckoning and sensor fusion for maximum precision.

Key Components and Technologies

Sensor Fusion : Integrates MEMS/FOG inertial sensors (accelerometers/gyroscopes) with satellite navigation (GNSS) to compensate for signal outages, often called "coasting" or "dead reckoning".
RTK (Real-Time Kinematic) : Provides centimeter-level accuracy by utilizing correction data from a base station or network.
AI & Kalman Filtering : Advanced algorithms (like those in Advanced Navigation systems) are used to process sensor data, track errors faster than traditional methods, and improve accuracy.
Modular/Rugged Design : Systems like the LN-351 offer military-grade, tightly coupled GPS/INS, often supporting M-code, P(Y) code, or C/A code.

Performance in Challenging Environments

Subsea & Maritime: Specialized solutions like Rovins 9-DVL combine INS with Doppler Velocity Logs (DVL) for precise underwater navigation.
Autonomous Driving & Robotics: Systems from vendors like SBG Systems and u-blox offer high-precision, high-integrity positioning necessary for safe, autonomous operation.
GNSS-Denied Areas: In cases where GPS is unavailable or jammed, these systems rely on high-performance gyroscopes and acceleration sensors to maintain position.

Common Applications

Surveying & Mapping: UAV/drone mapping, mobile mapping, and marine surveying.
Defense & Aerospace: Autonomous vehicles, missile guidance, and tactical navigation.
Industrial Automation: Construction and precision agriculture.
