Titan IIIC Guidance with the Carousel VB (Vehicle Borne) Inertial Guidance System.

摘要

The Titan 3C Standard Space Launch Vehicle,starting with Vehicle 26,will use the Carousel VB Inertial Guidance System for navigation,guidance and digital flight controls. This guidance system consists of a Carousel VB Inertial Measurement Unit (IMU) and a MAGIC 352Missile Guidance Computer (MGC). The C-VB IMU is a modification of the C-IVB inertial navigator currently in airline service as a primary navigation system. A unique feature of the Carousel IMU is that two of the three gyro/accelerometer sets are revolved at 1rpm with respect to the stable platform. The effect is to partially cancel certain instrument errors associated with the revolving instruments. Conversion of this instrument from commercial airline navigation service to guidance and control of the rocket boost vehicle presented a guidance software design task that is the subject of the report.
