Dual-Satellite Doppler Accuracy Prediction and Geometry Selection for Sparse LEO Signals of Opportunity
Qi Liu, Marc Fernández-Temprado, Antoni Reus-Bergas, Shuguo Pan, Wang Gao, Gonzalo Seco-Granados, et al.
Low Earth Orbit (LEO) satellites have emerged as a promising complement to GNSS for positioning in signal challenged environments. In sparse LEO signals of opportunity scenarios, Doppler positioning often relies on only one or two satellite passes, making positioning accuracy hig…
