Description
Summary:This study investigates the impact of including the Russian Globalnaya Navigazionnaya Sputnikovaya Sistema (GLONASS) and Global Positioning System (GPS) observables in the estimation of the GPS satellite and receiver interfrequency delay biases. Efforts to advance the total electron content accuracy are directly linked to improving the satellite and receiver bias estimation. This analysis is a preliminary assessment of the impact of including GLONASS observables in the bias estimation process. We analyze bias series from 84 globally distributed stations between 17 February 2015 and 31 March 2015. We find that inclusion of GLONASS observables in the biases retrieval algorithm systematically reduces receiver biases at 88% of the stations than when only GPS observables are used. The difference is
