• Correlation Analysis of Multipath Effects in GPS-Code and Carrier Phase Observations 

      Nahavandchi, Hossein; Joodaki, Gholamreza (Peer reviewed; Journal article, 2010)
      Multipath error is a limiting factor for successful ambiguity resolution in precise real-time kinematic GPS positioning, both in the carrier phase and pseudorange measurements. Understanding the temporal characteristics ...
    • Local ionospheric modelling of GPS code and carrier phase observations 

      Nahavandchi, Hossein; Soltanpour, Ali (Peer reviewed; Journal article, 2008)
      A limiting factor for successful ambiguity resolution in precise GPS positioning is the existence of un-modelled ionospheric errors in both the carrier phase and the pseudorange measurements. In this study, the ionospheric ...
