Using a portable star tracking system, we are able to obtain the geographical position of the observer, longitude, latitude and North direction. In this work, a new optimization method has been applied to improve accuracy in calculation of the observer position better than 6 arcsec (200 meters). In this method, we used 80 to 100 stars in each taken picture from the sky to apply optimization method. To obtain the accuracy it has been recorded observations for frequent 50 nights. In each night it has been taken 100 images.
