چکیده
INSTRUCTIONS The technology for ultra-precision machining has been developed rapidly and steadily. In recent years, the demand for free form, complex and microscopic cutting has increased as a result of the need for highvalue-added fabrication for items such as high NA glass lenses, micro-grooves, diffractive aspheric lenses and other optical components. The ultra-precision machine for cutting or grinding of these parts should have sufficiently high accuracy to achieve a fine surface. A highly accurate positioning system is one of the essential machine components. A good positioning system will improve the form accuracy, reduce surface roughness and increase productivity.

Ultra-wideband (UWB) technology provides considerable performance in many indoor localization problems thanks to its very wide spectrum and high-resolution characteristics. In this paper, we propose using the horizontal dilution of precision (HDOP) to decrease the localization error in indoor environments for UWB localization systems. To achieve this aim, first we determine the positioning accu...
