The Relationship Between Network RTK Solutions MAC, VRS, PRS, FKP and i-MAX

Frank Takac, Oliver Zelzer

Abstract:	Several competing Network RTK solutions exist in the market including MAC, VRS?, PRS, i-MAX and FKP. The advantages and disadvantages of these solutions have already been examined in existing literature in sufficient detail. However, a link between the various Network RTK solutions is not clearly described. In this contribution, the relationship between MAC, VRS?, PRS, i-MAX and FKP is examined. The results show that a variation of all Network RTK modes can be realised using standardised MAC data. However, the lack of standard definitions means that other realizations are also possible. The paper also shows that the network and rover solutions are connected. That is, the rover requires intimate knowledge of the processes applied by the network software and an estimate of the quality of the network correction information to process optimal position solutions. However, the lack of a standard definition for VRS?, PRS, i-MAX and FKP can often lead to inconsistent modelling at the rover. In some cases, inconsistent modelling can introduce significant measurement errors that can adversely affect the position solution.
