We suggest a new technique for processing GLONASS carrier phase measurements over medium length baselines. This technique exploits the use of IGS products (orbits and clock products) thereby increasing the reliability of ambiguity resolution and reducing the computational burden compared with previous GLONASS processing procedures. To test our proposed new processing technique, we selected three IGS stations in the Australian region and processed both GPS and GLONASS measurements for the period of March 11, 2011. The selected baselines, ranging from 400 - 900 km, gave deviations from 1 cm in the horizontal component and 2 cm in the vertical component between GLONASS and GPS baseline processing and GLONASS results and known IGS ITRF2005 coordinates. This indicates that the proposed technique has promise for continued use. Given improvements in the GLONASS constellation in the coming years, it is likely this technique can be used to process baselines over 1000 km with similar accuracy as GPS.
