    en.wikipedia.org/wiki/Inertial_measurement_unit

    An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. When the magnetometer is included, IMUs are referred to as IMMUs.

    The Delco Carousel — proper name Carousel IV — was an inertial navigation system (INS) for aircraft developed by Delco Electronics. [1] Before the advent of sophisticated flight management systems, Carousel IV allowed pilots to automate navigation of an aircraft along a series of waypoints that they entered via a control console in the cockpit.

  6. Gimbal lock - Wikipedia

    en.wikipedia.org/wiki/Gimbal_lock

    A well-known gimbal lock incident happened in the Apollo 11 Moon mission. On this spacecraft, a set of gimbals was used on an inertial measurement unit (IMU). The engineers were aware of the gimbal lock problem but had declined to use a fourth gimbal. [5] Some of the reasoning behind this decision is apparent from the following quote:

    The IBM Information Management System (IMS) is a joint hierarchical database and information management system that supports transaction processing. [1] Development began in 1966 to keep track of the bill of materials for the Saturn V rocket of the Apollo program, and the first version on the IBM System/360 Model 65 was completed in 1967 as ICS/DL/I and officially installed in August 1968.

    Ullage is often a secondary function of the reaction control system such as on the Apollo Lunar Module (LM). In his book Lost Moon , Jim Lovell recounted a description of a course-correction burn of the LEM's main descent engine to re-enter a free return trajectory to Earth during the successful recovery of the Apollo 13 capsule:
