The international GNSS Monitoring and Assessment System (iGMAS) is developed as a service platform for multi-GNSS and the Product Integration and Service Center (ISC) is the products reprocess center which provides global users with different time-delay products.The present paper focuses on the final products combination from different analysis centers and the emphasis is put on the consistency between different final products,then an initial assessment about the precision of final products is inhibited with one year data from iGMAS,including final satellite orbits,clock bias,Earth Rotation Parameters,global ionosphere map and troposphere products,and SLR measurements form ILRS are collected for validation of BDS and Galileo satellite orbits; meanwhile,the consistency between final orbits and ERP is analyzed.
