In order to improve the reliability and real-time performance of polarized skylight navigation, a independent position method based on multi-polarized lights was proposed and a navigation prototype was constructed. The prototype included five polarized light sensors, which were arranged in multi-direction array for the detection of polarization information in multiple directions of the sky. With the polarization information optimized and converged, the sun spatial position information was calculated more reliably and accurately. Finally, the position information of the prototype was determined according to the sun spatial position information, the time and the geomagnetic field information, thus realizing real-time position. The PC program of the prototype completed by LabVIEW can collect and process the date from the sensors in real time, meanwhile calculate and display the longitude and latitude of the location of the prototype synchronously, with a data update rate up to 10 Hz. The test results show that position accuracies are ±0.4° and ±1.2° in longitude and latitude respectively, which indicate that the navigation prototype is feasible and stable and can be applied to real navigations.
