Zusammenfassung:Disclosed is an integrated embedded complex navigation system with high reliability. The complex navigation system of the present invention includes: a function package including a functional package which is capable of temperature correction and includes a six-axis IMU, a three-axis earth magnetic field, and a single-axis altimeter; and a control unit receiving data of the function package to an I^2C bus. The control unit receives data of the temperature-corrected functional package, outputs data of the three-axis earth magnetic field, and outputs data of the single-axis altimeter to the I^2C bus to couple sensor signals through a sensor correction algorithm and output coupled data to a mainboard, thereby adding a temperature correction function to a low-cost IMU (MEMS) sensor and having an effect of providing a ten-axis sensor with a level of high-cost equipment performance. 고신뢰성 통합 내장형 복합항법 시스템이 개시된다. 본 발명의 복합항법 시스템은 온도 보정이 되며 6축 IMU를 포함하는 기능성패키지와 3축 지자계 및 1축 고도계를 포함하는 기능패키지, 및 상기 기능패키지의 데이터를 I2C버스로 수신하는 제어부를 포함하고, 상기 제어부는 온도보정된 기능성패키지의 데이터와 3축 지자계의 출력데이터 그리고 1축고도계의 출력데이터를 I2C버스로 입력받아 센서보정 알고리즘 등을 통하여 센서 신호들을 결합하고 결합한 데이터를 메인보드로 출력하도록 구성함으로써 저비용 IMU(MEMS) 센서에 온도 보정 기능을 더하여 고가의 장비 성능 수준의 10축 센서를 제공할 수 있는 효과가 있다.
