Purpose: The purpose of this knowledge base article is to explain the method of integration known as Coning and Sculling used by Inertial Labs.

Updated: March, 2020

For strap-down based inertial sensors, the method of integration known as sculling (for linear accelerations) and coning (for angular rates) has been implemented for all Inertial Labs sensing components to reduce the erroneous build up of seemingly valid measurements of accelerations and angular rates. These errors, if left unaccounted for then produce further errors in calculations for velocity and attitude in inertial based navigation systems and attitude and heading reference units.
