We compute the expected sensitivity on measurements of optical depth to reionization for a ground-based experiment at Teide Observatory. We simulate polarized partial sky maps for the GroundBIRD experiment at the frequencies 145 and 220 GHz. We perform fits for the simulated maps with our pixel-based likelihood to extract the optical depth to reionization. The noise levels of polarization maps are estimated as 131 $\mu$K arcmin and 826 $\mu$K arcmin for 145 and 220 GHz, respectively, by assuming a three-year observing campaign and sky coverages of 52% for 145 GHz and 45% at 220 GHz. Our sensitivities for the optical depth to reionization are found to be $\sigma_\tau$ = 0.031 with the simulated GroundBIRD maps, and $\sigma_\tau$ = 0.011 by combining with the simulated QUIJOTE maps at 11, 13, 17, 19, 30, and 40 GHz.
