DEVICE TO INTEGRATE STANDBY INSTRUMENT INTEGRATED SYSTEM ORIENTATION UNIT WITH AIRCRAFT INSTRUMENTATION COMPLEX Russian patent published in 2015 - IPC G01C21/00 

FIELD: aircraft engineering.

SUBSTANCE: device comprises rotary transformer, unit of primary data transducers, ADC, computer, external interface shaper, microcontroller with ADC, null device, galvanic isolation unit, synchroniser, inverter and two conversion channels. Each of aforesaid components incorporates switch buffers connected in series with null device input. Comparator output is connected to microcontroller and switch control input. Switch control unit output is connected to ADC input while its outputs are connected to inverter input and output, said ADC being built in said microcontroller. Note here that buffer input of one channel is connected to sine winding of rotary transformer. Buffer input of the other channel is connected to sine winding of rotary transformer. Galvanic isolation unit input is connected to external reference voltage source which supplies the rotary transformer excitation winding incorporated with aircraft instrumentation complex.

EFFECT: enhanced performances.
