| Resumo: | Real-time kinematic (RTK) GNSS delivers centimeter-level positioning accuracy and is foundational to applications that monitor slow movement phenomena. However, its reliance on continuous operation incurs substantial energy costs, limiting viability for long-term, battery-powered deployments. This study presents a comprehensive experimental evaluation of duty-cycled RTK for high-precision quasi-static monitoring. Through a series of controlled and field experiments, we systematically quantify the relationship between duty-cycle configuration, convergence latency and positioning accuracy. Results show that duty cycles as low as 1 minute per hour achieve sub-centimeter horizontal accuracy, while 15-minute cycles per hour achieve performance almost identical to continuous operation. A four-month deployment over a known subsidence zone demonstrates sub-millimeter-per-month agreement with optical system measurements, validating the method's real-world geodetic performance. As duty-cycle reduction almost directly translates into equivalent energy savings, these findings establish duty-cycled RTK as a viable strategy for energy-efficient, high-precision GNSS monitoring, enabling scalable deployment in power-constrained scenarios. |
