To set and to configure specific parameters of the RTK engine.
The Ambiguity group of settings:
Fix level - select the level of confidence for ambiguity resolution; that is, for getting a fixed RTK solution: Extra-low, Low, Medium, High, and <Don't Set>.
These levels correspond to different probabilities of correct ambiguity resolution. During a GNSS survey in the RTK mode, when selected confidence level is achieved, the corresponding position will be marked as a fixed RTK solution (although some of the ambiguities - usually a small part of them - may remain float). The higher the confidence level is specified, the lower probability of getting a false fixed solution is, but the longer the integer ambiguity search time is.
If the <Don't Set> value is selected, the level that was previously set in the receiver will be used (i.e., the level set before the controller with current job was connected).
Other settings:
Accept noisy observables - after clicking the check box, the RTK engine will use less rigid thresholds for computing RTK solution. This parameter allows the user to speed up the ambiguity fixing procedure, but it also decreases the reliability of the ambiguity resolution. This parameter can be used for abnormal survey conditions only:
