On the panel, you can control the integer ambiguity fixing process. Make sure that you have chosen suitable biases. Otherwise, ambiguity fixing is impossible.
Start WL-Fixing after …. seconds: Define after which time [seconds] the WL Fixing with the HWM LC is started.
Start other fixing after …. seconds: Define after which time [seconds] raPPPid should fix all other ambiguities (e.g., NL or L1).
Elevation Cutoff for Fixing: The ambiguities of satellites under the specified elevation angle [°] are not fixed.
Exclude satellites manually from fixing: The listed satellites (e.g., G04 or 113) are not used in the ambiguity fixing process. Please use ' ' or ',' as a separator. In the case of fixing BeiDou satellites, it might make sense to exclude IGSO satellites from the fixing process. Note that, for example, the command E01:E03 works and excludes the Galileo satellites E01, E02, and E03 from the fixing procedure. Therefore, entering E01:E99 prevents fixing Galileo ambiguities.
Select a method for choosing the reference satellite. The reference satellite is used in the ambiguity fixing process to build single-differences and eliminate the receiver phase biases.
Highest satellite: The satellite with the highest elevation is selected for each GNSS as reference satellite
manual choice (list): The reference satellite is chosen with the provided hierarchical list. If no wanted satellite is observed, the highest satellite is chosen.
The WL ambiguities are fixed by averaging the SD HMW LC. The default values usually lead to satisfactory results. However, for low-cost equipment or long time periods (e.g., over 2 hours), changing these parameters might improve the fixed solution (e.g., stability).
Fixing threshold: The difference between the average value of the HMW LC to the next integer is calculated. The WL is fixed if it is below the specified threshold [cy].
Releasing threshold: The fixed WL ambiguities are checked every epoch. If the difference between the average value of the HMW LC to the next integer is above the specified threshold [cy], the WL fix is released.
Fixing window: The HMW LC observations of the specified time period [s] are used for averaging.
