▎EW Mesh

Inertial Navigation System/ INS

Self-contained PNT computed from accelerometers and gyroscopes.

Definition

An INS integrates accelerometer and gyroscope measurements to maintain position and attitude without external reference. It is the GNSS-independent backbone of every modern autonomous platform and the anchor for fusing GNSS, vision, and Alt-PNT sources under EW conditions.

Reference attributes

Sensors: IMU (accel, gyro)
Property: Self-contained, drift-prone
