Integrated travel control and attitude heading reference system

A method comprising:

• receiving inertial data at first processing circuitry through interface circuitry, where the interface circuitry communicatively couples the first processing circuitry to second processing circuitry;
• using the received inertial data, generating attitude and heading data using the first processing circuitry;
• communicating the generated attitude and heading data to the second processing circuitry through the interface circuitry;
• receiving a command signal;
• using at least one of the generated attitude and heading data and the received command signal, generating one or more vehicle control signals to alter vehicle velocity using the second processing circuitry;
• and
• issuing the one or more vehicle control signals from the second processing circuitry through the interface circuitry to alter vehicle velocity.

A system, comprising:

• first processing circuitry configured to determine attitude and heading data of a vehicle using inertial data;
• second processing circuitry configured to control at least one component of the vehicle using the attitude and heading data, and at least one command signal, wherein the at least one component is configured to alter a velocity of the vehicle;
• and
• interface circuitry communicatively coupled between the first processing circuitry and the second processing circuitry, wherein the interface circuitry is configured to receive the inertial data, to provide the inertial data to the first processing circuitry, and to provide the attitude and heading data to the second processing circuitry, and wherein the interface circuitry comprises an interface to at least one of (a) at least one bus and (b) at least one network shared by the first processing circuitry and the second processing circuitry.
