초록
This study explores the applicability of Low Earth Orbit Positioning, Navigation, and Timing (LEO PNT) technology to enhance the performance of Korean satellite navigation systems. While LEO PNT technology is actively being developed worldwide, Korea has made significant advances in satellite navigation with the successful development and launch of the Korea Augmentation Satellite System (KASS) and the commencement of the Korean Positioning System (KPS) development. This paper proposes a configuration of a LEO PNT system to augment the performance of KASS and KPS, thereby improving the independence and accuracy of Korean satellite navigation systems. Utilizing simulation techniques, the study evaluates the performance of a PNT system using a small number of LEO satellites and analyzes the potential impacts and benefits of the LEO PNT on satellite navigation systems. It is anticipated that the results of this research can be used to suggest a direction for the development of Korean satellite navigation systems and will contribute to enhancing the international competitiveness of future satellite navigation technology.
