Precise timing is crucial for satellite navigation because even small time deviations can lead to serious positioning errors.
Traditional systems rely heavily on ground-based atomic clocks, but this carries the risk of service disruption.
To meet these challenges, the scientific community needs advanced research to develop more reliable and autonomous satellite timing systems.
, According to foreign media reports, researchers at the University of Chinese Academy of Sciences and the Institute of Microsatellite Innovation of the Chinese Academy of Sciences have proposed a novel two-level timing system that uses sparse sampling Long Short-Term Memory (LSTM) algorithm to improve the accuracy and stability of satellite navigation timing.
Relevant research has been published in the journal Satellite Navigation.
