The invention discloses a course and attitude reference system based on a polarization compass. The system comprises a sensor module, a polarization sensor data processing module, a multi-sensor information fusion module, a storage module, a communication module, a power module and an interface circuit; the sensor module comprises the polarization compass, a gyroscope, an accelerometer, an air pressure sensor, a temperature and humidity sensor, a geomagnetic sensor and a GPS; intelligent fusion of data of the polarization sensor data processing module and multi-sensor information fusion moduleare completed by an ARM chip; the interface circuit comprises a data transmission interface and a command output interface, the power module supplies power to the system, and the storage module is used for storing navigation data. The course and attitude reference system based on the polarization compass has the advantages that a bionic polarization navigation is used for determining course and attitude information of un
