Sammanfattning: This thesis is an accuracy research of detail surveying with networkRTK. Another objective of the thesis concerns some proposed controlmethods and to estimate if they are practically useful, and if the theoreticalassumptions of accuracy levels can be adjusted to standardisedtolerances for such control methods.The control methods are “revisit with network RTK” and “separatecontrol with conventional technique”, both in plane and height. Therevisit can be processed alone, or integrated with the productionmeasurements. Conventional technique involves a totalstation or alevelling instrument. The authors consider the control methods to bepractically useful.The modification of the theoretical assumptions of accuracy levelshas been based on an extensive material of measurements, calculations,analyses and considerations. This thesis achieved a standarderror in plane of 10 mm and in height of 15 mm (without the standarderror of the geoid model), which is comparable with similarstudies carried out lately. However, the conditions in this study areconsidered to be very favourable. To achieve the accuracy in plane, atripod of some type is necessary to minimize the influence from thecentering standard errors.Our modified accuracy levels can in the future be adjusted to standardisedtolerances, but more studies at different locations andunder other conditions are then necessary.
