Macrometer observations were carried out by Hessisches Landesvermessungsamt for two days in 1983 and for four days in 1984. The simultaneous adjustment shows the necessity to introduce more than one set of transformation parameters, if there is a great space of time between the measurements or if the scale of the terrestrial net changes within the area of measurements.
