The Critical Role of Inertial Navigation in Armored Combat Vehicles: Ensuring Precision in GNSS-Denied Environments
3 September 2024
What is the definition of initial bias?
After switch-on and when the gyroscopes and accelerometers are both stationary and in a thermally stable state, the sensors will present a measurable output or offset error, regardless of zero rotational or accelerative forces. This initial bias can vary from switch-on to switch-on due to thermal, physical, mechanical, and electrical variations between measurements.
