Positioning optimization of a low cast portable star tracker up to 200
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.
