Abstract
A low-orbit satellite ephemeris resource adaptive parsing method and device based on dual-mode switching, the method divides the application scenarios of the terminal to the ephemeris data into two categories, and correspondingly adopts a switchable dual-mode calculation architecture: in the prediction mode, fast visibility judgment is performed, in the calculation mode, complete precision calculation is performed, and the length and step of the output table are configurable. Through the above automatic switching mechanism, the accurate matching of the calculation resources and the communication demand is realized, so that the link quality is guaranteed while the terminal power consumption and memory occupation are greatly reduced.
