Abstract

Abstract

We proposed a method to accurately acquire the sin wave curve of strap-down north seeking signal acquisition system at different latitudes. According to the current value of dynamically tuned gyro output at different latitude we designed a system which can automatically adjust the sample resistor value using digital potentiometer. The data processing system calculates the latitude automatically based on dynamically tuned gyro signal and then the signal acquisition system resets the acquisition resistor value, and thus we can acquire the sin wave curve efficiently. Using this method we ensure that the north finder can meet the accuracy requirements at different geographical latitudes, and has strong adaptability and high stability.
