The tester of resolver type aeronautical gyro horizon uses the analog resolver to provide the testing signal generally and its assigned error is big.The more advanced aeronautical gyro horizon tester provides the testing signal through the digit resolver,but the tester price is high.A detail design method was proposed of an aeronautical gyro horizon tester based on a digital sine-cosine resolver.The digital sine-cosine resolver was self-developed and its price is low and precision equals the existing product,so the tester's performance-to-price ratio is obviously enhanced.The practical application proves that this tester works stably and its testing result is accurate.The problems existed on the above aeronautical gyro horizon tester are well resolved.
