Article: How Inertial Navigation Systems Work

Published: 30 Mar 2020 by

OxTS inertial navigation systemOxTS, a developer of inertial sensing solutions for UAVs (unmanned aerial vehicles) and robotics, has published an in-depth article explaining the operation of inertial navigation systems (INS), including their core components and the quantities measured.

Read the full article on OxTS’ website here

The article covers:

  • The difference between GPS and INS
  • Stabilised and strap-down navigation computers in INS
  • Frames of reference and measurements in 3D space
  • Accelerometers and the measurement of proper acceleration
  • Gyroscopes and MEMS angular rate sensors
  • Dead reckoning and combining accelerometer and gyro measurements
  • How drift accumulates in INS

Inertial navigation systems use multiple inertial sensors to calculate the position, orientation, and velocity of a moving object, and are a core component of many unmanned systems, including UAVs, drones, UGVs (unmanned ground vehicles) and UUVs (unmanned underwater vehicles).
