The star tracker can be used for navigation of a satellite if it is combined with the earth sensors. This paper addresses the development of test-bed for a star tracker algorithm which is one of the most important elements of satellite navigation algorithm. The test-bed is composed of the monitor to display star images, camera to emulate the star tracker, the adjustable frame to support the camera and monitor, the computer with algorithms for image processing and attitude etermination. Various considerations to enhance the accuracy of the test-bed are described even though the test-bed is low-cost.
