Ternary microprocessor based autopilot design and implementation

This dissertation presents a complete design and implementation of a ternary microprocessor based exoatmospheric autopilot system. An efficient and robust structure of an autopilot system is introduced in the new framework of the ternary autopilot system. From the hardware point of view, the ternary system has many advantages over the binary system such as lower power consumption, fast processing time, simple structure and robust arithmetics.

The ternary microprocessor based exoatmospheric auto pilot system including the ternary valve servo system is designed using the above hardware descriptions to cover all possible onboard calculations, preprogrammed missions and self-diagnostic capability. This system also gives effective torque combinations into the reaction jet servo system. The functional operations of this ternary auto pilot system are better than those of a binary processor based autopilot system.

This ternary autopilot processor can be reduced to few small blocks using VLSI techniques for an effective airborne system, and this framework of the ternary autopilot system can be applied in any other exoatmospheric vehicle system.
