    While GPS coordinates are fixed, there sometimes exist the problem of angular swing between each station.

      Hi Jansen,
      What is the remedy for that,
      I have not used GPS for fixing.
      When we require the cadastral allotments in one system when we come
      across an error!
      This is not for GIS.....
      Also satellites orbits may change according to owners of those according to
      GPS manuals,
      Thanks ,
      Lalith
