A Review of the Key Role of Satellite-Terrestrial Direct Connection Technology in Navigation Enhancement
摘要
Abstract
This review focuses on the key role of 6G-oriented satellite-terrestrial direct connection technology in navigation enhancement.With the development of fields such as intelligent transportation,traditional navigation technologies are facing challenges in positioning accuracy and real-time performance.By relying on multi-satellite cooperative transmission,delay correction algorithms,and combined with efficient decoding algorithms,satellite-terrestrial direct connection technology can significantly improve positioning accuracy while effectively reducing propagation delay,thus contributing to the efficient operation of satellite-terrestrial communication and positioning systems.The research elaborates on three core technologies:multi-satellite multi-beam coordination,delay correction,and decoding,and analyzes their research progress,advantages,and challenges.Among which the multi-satellite multi-beam coordination technology can achieve seamless global coverage and enhance system capacity;the delay correction technology can suppress ionospheric and tropospheric delay errors to ensure communication reliability;the decoding technology overcomes signal transmission interference to guarantee accurate and efficient data transmission.Through their synergistic effect,these technologies jointly build a high-precision and low-latency navigation and communication system,which not only supports the development of the 6G space-air-ground integrated network but also promotes the transformation of satellite communication from emergency and coverage supplementation to a mainstream communication method.关键词
