GPS Displacement Monitoring System

Under good satellite visibility, you can achieve horizontal accuracy of 5–10 mm and vertical accuracy around 10–15 mm using standard L1/L2 receivers. With RTK corrections or post-processing, sub-centimeter results are common. The exact precision depends on baseline length, multipath environment, and processing method. Kingmach helps configure the system to meet your project's accuracy requirements.

Most Kingmach stations use local data logging and can transmit via satellite modems or radio links when cellular networks are unavailable. The on-board storage holds months of data, so even if communication drops temporarily, no measurements are lost. Alarms can be configured to trigger SMS alerts directly from the station.

Dense foliage and steep terrain can block satellite signals, reducing accuracy or causing outages. In such cases, it's common to combine GPS with other sensors like total stations, tiltmeters, or crack meters. Kingmach's team can assess the site and suggest a hybrid monitoring approach if GPS alone isn't sufficient.

Routine maintenance mainly involves cleaning solar panels, checking cable connections, and verifying that vegetation hasn't grown to obstruct signals. The equipment is designed to operate for years with minimal intervention. Remote diagnostics help identify issues before they affect data quality, and Kingmach offers annual service contracts for inspections and recalibration.

A single station can typically be installed in a day once the concrete pillar or mount is ready, and data starts flowing as soon as power and communication are established. For larger networks, planning and site preparation take longer, but Kingmach's team provides guidance on pillar design, antenna mounting, and grounding to streamline the process.
