Abstract

This study examines the creation of an advanced model for Low Earth Orbit (LEO) satellites within the framework of Global Navigation Satellite Systems (GNSSs). The growing interest in LEO satellites, due to their potential navigation and communication benefits, has necessitated a standardized model for LEO broadcast ephemeris. Current models often overlook key factors like orbital altitude, eccentricity, and inclination, compromising reliability. We offer a refined19-parameter model considering these factors. Our methodology for parameter selection is rigorous and validated using real LEO satellite data. Despite having fewer parameters, our model offers improved accuracy, reliability, and efficiency for LEO satellite navigation.
