INS fusion uses an Inertial Navigation System with internal sensors (accelerometers and gyroscopes) to calculate position, speed, and heading when GPS drops out. It provides dead reckoning from the last known GPS fix, keeping vehicles visible on tracking maps with a growing 'position uncertainty' ellipse around them, preventing total blackout of situational awareness during signal denial.Related FAQs: How does electronic warfare jamming affect GPS trackers in fleet operations? | When should fleet managers upgrade their entire tracking system versus applying patches for GPS jamming?
