(navigation)
Inertial navigation equipment in which a stable platform and gimbal system are not used: the inertial devices are attached or strapped directly to the carrier; a computer utilizing gyro information resolves accelerations sensed along the carrier axes and refers these accelerations to an inertial frame of reference. Also known as gimballess inertial navigation equipment.
