An Improved QZSS Satellite Clock Offsets Prediction Based on the Extreme Learning Machine Method
The Japanese Quasi-Zenith Satellite System (QZSS) has been developed as a GPS (Global Positioning System) complementary system to improve positioning accuracy in the Asia-Pacific region.However, the accuracies of ultra-rapid predicted clocks are not high enough for real-time applications, so it is still a challenge problem.This article focuses on t
