  Present cosmic microwave background (CMB) observations have significantly
advanced our understanding of the universe's origin, especially with primordial
gravitational waves (PGWs). Currently, ground-based CMB telescopes are mainly
located in the southern hemisphere, leaving an untapped potential for
observations in the northern hemisphere. In this work, we investigate the
perspective of a northern hemisphere CMB polarization telescope (NHT) to detect
PGWs and present mock data for such a project. We forecast the detection
sensitivity on the tensor-to-scalar ratio r of NHT and compare it with the
existed ground-based experiments, also search for optimal experimental
configurations that can achieve the best sensitivity of r. Our results indicate
that, considering realistic experimental conditions, the first year of NHT
observations combined with Planck can achieve a precision of \sigma (r)= 0.015,
reaching the level of BICEP2/Keck, with significant potential for improvement
with subsequent instrumentation parameter enhancements.
