　　A new processing approach is proposed for the Ultra-orbit orbit product of international GNSS Monitoring and Assessment System (iGMAS) analysis center.With this approach,a length of 22 hour normal equation matrix and 3 hour normal equation matrix are combined into a complete one to determinate the satellite orbits,which can satisfy the 2 hour submit delay required by ultra-rapid products.
