摘要
Abstract
The integration of communication,navigation and remote sensing is the evolutinary direction for future low earth orbit(LEO)satellite Internet to achieve ubiquitous integrated space-based information service.To expand the utilities of existing communica-tion constellations,a multi-satellite joint positioning scheme has been designed,which utilizes the Doppler shift carried by communica-tion signals to obtain the geographical location information for target terminals.Furthermore,a practical Doppler shift estimation algo-rithm has been proposed,which can address the issue of LEO satellite Doppler shift exceeding the subcarrier spacing of OFDM system.Finally,through link-level simulation,the positioning performance of the proposed scheme for target terminal has been validated.关键词
