Inertial Navigation Systems (INS)

Basic Principle: measures acceleration against time to determine speed and direction

How: uses accelerometers, in a gimbal assembly, to sense all vertical and horizontal accelerations to provide position and steering information.

Information Provided:
  • steering information to autopilot
  • aircraft attitude information for flight instruments
  • antenna stabilization for airborne weather radar
  • horizontal navigation data
