Abstract:	A working group within RTCM SC104 for the standardization of network RTK messages has consolidated various message proposals put before the committee over the past 3 years and interoperability testing is currently underway. Therefore, an industry-wide network message standard is forthcoming. Euler and Zebhauser (2003) and Euler et al. (2003) investigated the feasibility and benefits of standardized network corrections for rover applications. The Master- Auxiliary concept, described in Euler et al. (2001), as the network RTK message format. The analysis, focused primarily in the measurement domain, demonstrates that double difference phase errors can be significantly reduced using standardized network corrections. This paper extends the analysis of standardized network RTK messages for rover applications to the position domain. The results of baseline processing demonstrate effective, reliable and homogeneous ambiguity resolution performance for long baselines (>50km) and short observation periods (>45 sec). Overall horizontal and vertical positional accuracy is also improved when network corrections are employed.
