    GPS to True = 103.395 / 103.453 = 0.99943936
    GPS distance x 0.99943936 = True distance

    Is this what you needed?

      Dear Jim,

      I have a relevant question.

      I have a list of GPS control points. and I am trying to make a traverse using Toral station.

      but each one of the points has a different scale factor.

      isn't the scale factor suppose to be calculated from the distance between two points as in the question above?

      in this case, should I measure the distance from the site and calculate a new scale factor or use one of the scale factors which is on the list or calculate an average of them?

      Thanks in advance
