1. A system, comprising:
a first processing system comprising first processor circuitry and configured to determine attitude and heading data of a vehicle using inertial data;
a second processing system comprising second processor circuitry and configured to issue one or more vehicle control signals to control at least one component of the vehicle using the attitude and heading data, wherein the at least one component is configured to alter a velocity of the vehicle, and wherein the second processor circuitry is fault tolerant; and
an interface circuit communicatively coupled between the first processing system and the second processing system, wherein the interface circuit is configured to receive the inertial data, to provide the inertial data to the first processing system, to provide the attitude and heading data to the second processing system, and to receive the issued one or more vehicle control signals from the second processing system, and wherein the interface circuit comprises an interface to at least one of (a) at least one bus and (b) at least one network shared by the first processing system and the second processing system.
