gnss-toolbox's Issues

Failing XTR-utils functions

Hi:
When I try to run the matlab code , I got an error like this :

Error dataCell2matrix (line 3)
timeStamp = cellfun(@(c) datetime(c(9:27),'InputFormat','yyyy-MM-dd HH:mm:ss'),

dataCell);

Wrong use of cellfun
The datetime output type is not supported. Please set'UniformOutput' to false.

How should I improve the code?

Thank you very much!

Using SATPOS with existing sp3 file

Hello and thanks for the awesome tool
I was wondering how I can use the SATPOS program with my own SP3 file. If I provide the fullpath to it the code still tries to download the CODE files.
Thank you

Fix function "downloadBroadcastMessage" for GPS and GLONASS satellites

For now function downloadBroadcastMessage uses FPT server igs.bkg.bund.de to download navigation messages for GPS and GLONASS, however it is preffered to download them from server cddis.gsfc.nasa.gov (as it did previously).
Problem is that current server at cddis.gsfc.nasa.gov is using HTTPS and require registration at https://urs.earthdata.nasa.gov.

Matlab has problem retrieve data even after correct credentials are provided, so maybe the workaround with curl or wget will be neccessary (follow steps at this guide).

Reading 0s accuracy codes in sp3 file

Code "SP3" seems to have an issue reading sp3 headers that are formatted like this:

+   52   G01G02G03G04G05G06G07G08G09G10G11G12G13G14G15G16G17

instead of this:

%c M  cc GPS ccc cccc cccc cccc cccc ccccc ccccc ccccc ccccc

i.e., will complain for the lines that contain only 0s..

Wondering if this is a bug that's easy to fix

Thank you

Loading SP3

Hello,
first of all, thank you for your time and effort in making this toolbox which is really interesting.
I am new to the coding world, so treat me as someone who doesn't know anything related to coding, but i really need to use your toolbox in my studies. and i would appreciate it if i am allowed to do that and i will acknowledge all your work.

I am trying to load SP3 file i downloaded from cddis.gsfc.nasa.gov but i dont know which file i should open and put the directory to.
sio07006.zip

Again, thank you for your time.
