7 Additional ExamplesThe results are analogue to the zero difference case previously described:...A POSTERIORI SIGMA OF UNIT WEIGHT (PART 1):------------------------------------------A POSTERIORI SIGMA OF UNIT WEIGHT : 0.0000 M (SIGMA OF ONE-WAY L1 PHASE OBSERVABLE AT ...DEGREE OF FREEDOM (DOF) : 55605CHI**2/DOF : 0.00...The ambiguities are set up in a way that the correct resolution for all ambiguitiesis zero in any case. This is an easy way to verify ambiguity resolution strategies.7.4.4 Final RemarksThere are many opportunities to use this simulation tool. It depends on your needs andthe concrete target of the simulation study to define the experiment. As it was justdemonstrated the full consistency between the processing and the simulation programs isguaranteed by the Bernese GNSS Software.The big advantage of a simulation is that the correct solution is known a priori. On theother hand, you have to keep in mind that the simulated data can only contain effectsincluded in the simulation model. If a receiver for instance introduces a significant variationof the inter–system bias between GPS and GLONASS data — an effect that is notconsidered in the simulation model — the influence of such an effect on the results cannotbe evaluated by the simulation.Page 144AIUB
