Li et al. deployed a method which conducts Geomagnetic FP with in a result of Wi-Fi FP. This method has a problem that an accuracy gets down if the accuracy of either FP is low. To solve this problem, we propose an stable indoor positioning method, which calculates a position with the weighted average of Wi-Fi FP and Geomagnetic FP whose search space limited by AP (Wi-Fi Access Point)'s BSSID. As a result, mean error, median error and rate of positioning failure are 6.95m, 3.48m and 0% respectively. Probabilities that positioning errors are equal to or less than 5m of proposed method and Li's method are 48% and 28% respectively when AP's BSSID in the experiment environment was reduced 75% at random.
