摘要: Space-based global positioning systems are three-dimensional measurement systems that use radio signals from a constellation of satellites orbiting the Earth. They comprise a satellite navigation system designed to provide instantaneous position, velocity, and time information almost anywhere on the globe at any time. This technology is used in numerous areas such as unmanned systems, missiles, commercial and military aviation. The United States NAVSTAR Global Positioning System and Russian Global Navigation Satellite System (GNSS) are fully operational and used by different nations. Because of the technologys essentiality, most countries aim for independence; however, this is a big problem for developing or non-space faring countries because of the cost of the systems. To decrease the cost of a position navigation and timing (PNT) constellation, some nations develop regional PNT systems. In this research, GNSS systems, regional navigation satellite systems and satellite-based augmentation systems are analyzed, and an independent regional timing and positioning system satellite constellation over Turkish territory is reviewed using the AGI Systems Tool Kit software.
