df_estimated_velocities_gmwmx
                        Estimated northward and eastward velocity and
                        their standard deviation using the GMWMX

gmwmx2                  Estimate a trajectory model for a 'gnss_ts_ngl'
                        object considering a white noise plus colored
                        noise as the stochastic model for the residuals
                        and model missingness with a Markov process
                        using the GMWMX estimator.
