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

TL;DR

This paper presents a new optimization method for a portable star tracker that improves observer position accuracy to better than 6 arcseconds (200 meters) using multiple star observations over 50 nights.

Contribution

The work introduces a novel optimization technique that enhances the positional accuracy of low-cost portable star trackers beyond previous capabilities.

Findings

Achieved position accuracy better than 6 arcsec (200 meters).

Utilized 80-100 stars per image for optimization.

Collected data over 50 nights with 100 images each night.

Abstract

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.
