how to enable receiver DCB estimation ?

I try this program with the smartphone data from google .However, the results are terrible. How to get a reasonable results. Can you share a setting file and paramter file?

What I want to express is that when using the lambda method to fix narrow-lane ambiguities, shouldn't we use the variance matrix of the narrow-lane ambiguities? However, the code uses the covariance matrix of ionospheric single-difference ambiguities. Will this have an impact on the positioning results?

While open it gives me this error ( Error : Saving default parameters failed )

how can I fix it ?

Thanks

According to the test of the software, it seems that the support of the Beidou-3 satellite is not friendly, and it is not fully displayed in the drawing interface, and only the 28th satellite is supported

Which MATLAB version should I use?

I used MATLAB R2018a but it always shows following problem:

wrong use append (line 38)
Wrong number of input arguments for obsolete matrix-based syntax.
error at ElevationWeightingFunction (line 23)
funstring = append('@(e)', funstring);
error at getSettingsFromGUI (line 349)
ElevationWeightingFunction(get(handles.edit_elevation_weighting_function, 'String'));
error at GUI_PPP>GUI_PPP_OpeningFcn (line 100)
settings = getSettingsFromGUI(handles); % get input from GUI and put it into structure "settings"
error at gui_mainfcn (line 220)

feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});
error at GUI_PPP (line 28)
gui_mainfcn(gui_State, varargin{:});

error at raPPPid (line 15)
GUI_PPP();

Does the current program not support TF PPP-AR?If it is supported, how to set it？

When you start the GUI, the program always reminds you that QZSS is not in class F.

After loading the observation file, this error appears , how can I fix it ?

Thanks

In the PPPAR mode, I noticed that the setting for phase in the bias configuration is "off." Is this because the phase observations do not require bias correction for ambiguity fixing?

My question is why using code products is not suitable for correcting code observations in OSB products.

error happened while processing with multi freq option , but not happen with dual freq option

The formatting of the Rapid ERP files from IGS differ slightly from the final product. Due to this difference, read_erp fails when attempting to read those files.

I use MATLAB 2018a and change folder to /WORK folder, but an error occur when I start the raPPPid.m
it shows : please check the current folder and path.m

Hi, I am a little confused about the uncombined PPP model in your paper, the term DCB1i is presented in equations (7) and (8). In my understanding, the receiver DCB is not involved in phase observable. Could you please provide some clarification on this term?

How can I get the RMS for North, East and Up (cm) and convergence time (epoch) values after processing ? is there an option for this in the code ?

%% Solve all Narrow-Lane ambiguities at once with LAMBDA method

Is the variance-covariance matrix Q_NN_SD representing the variance of the ionospheric delay replacing the variance matrix of the narrow alleyway ambiguity here?

When i run the file raPPPid.m, it shows an error that let me check current folder and the class Path.m。I see the file path.m and I just don't know how to change the 'Path of TUW ionosphere models'.
