STEPDATAPROCESSOR FOR 180X OG 90X KOMPAS-SYNCRODATA

A compass data converter converts 180X and 90X synchro compass data to 1/6 degree step data. 180X synchro data is converted by utilising a 360X to 1/6 degree step data converter that divides the synchro rotation into six 60 degree sectors providing a digitial step data code representative thereof.

Zusammenfassung:	A compass data converter converts 180X and 90X synchro compass data to 1/6 degree step data. 180X synchro data is converted by utilising a 360X to 1/6 degree step data converter that divides the synchro rotation into six 60 degree sectors providing a digitial step data code representative thereof. A 180X converter further sub divides the 60 degree sectors into 30 degree sub sectors by selecting a synchro output in accordance with the step data code from the 360 X converter and comparing the selected synchro output to ground to provide an additional step data digit. The converter for 90X data further sub-divides the 30 degree sub-sectors into 15 degree intervals by selecting two synchro outputs in accordance with the 360X step data code and the additional step data digit and scaling one of the selected synchro outputs to equal the other selected synchro output at the 15 degree interval boundaries. A comparison of the selected unscaled synchro output and the selected scaled synchro output provides a fifth step data digit for the 90X code.
