Query about bad gps data as an input of rtabmap

[Masoumeh]

hi mattieu,

one of the input for slam is GPS, so it might happen that in some parts of the environment GPS would not work properly (shows nan for latitude, longitude, and altitude). how rtabamp slam manage this type of input?
does rtabmap merge these kinds of data with the other sensors' data? or how do you filter out this information?

thanks
