RTCM 3.0 implementation in network RTK and performance analysis

This thesis discusses the RTCM 3.0 implementation in network RTK positioning using the Department of Geomatics Engineering PLAN Group's network software, MultiRef(TM), and addresses novel features of the new standard. Post-mission tests have been performed with field data from the Southern Alberta Network (SAN). Three interpolation techniques are discussed, namely the distance-weighted, plane and collocation methods.; Results show that the RTCM 3.0 approach is a preferable implementation for network RTK positioning by reducing the sizes of the network RTK corrections. All three interpolation techniques are effective and obtain similar results in the position domain when the network ambiguities are properly resolved. However, when the network software is incapable of resolving many of the network ambiguities, the network approach does not show significant improvement over the single baseline approach when Kinematic Ambiguity Resolution (KAR) is enabled. When KAR is disabled, i.e. positions are computed using the IF mode, the network approach is marginally better than the single baseline approach.
