Abstract

A ternary-microprocessor-based exoatmospheric autopilot system including a ternary valve servo system is designed in which the ternary processor and ternary hardware cover all navigational calculations and preprogrammed missions. The exoatmospheric autopilot system was designed completely with the symmetrical ternary (-1, 0, and +1) logic scheme. This system gives effective torque combinations into the reaction jet servo system. The functional operations of this ternary autopilot system are shown to be better than those of a binary-processor-based autopilot system. This ternary autopilot system can be reduced to few small blocks using CMOS circuits and VLSI techniques for an effective vehicle system
