CARIGARA, Leyte – Meant to provide more accurate and reliable data, the Department of Public Works and Highways (DPWH) Leyte Second District Engineering Office upgraded its Real Time Kinematic (RTK) equipment, from 3-kilometer straight-line radius coverage to 70 kilometers.

RTK is a satellite navigation system that is used for measurement and survey of land areas. It enhances the accuracy of position data derived from satellite-based positioning technologies and uses measurements of the phase of the signal's carrier wave.

The new survey system will now reach the 14 municipalities of the second district of Leyte, namely, Barugo, Burauen, Capoocan, Carigara, Dagami, Dulag, Jaro, Julita, La Paz, Mac Arthur, Mayorga, Pastrana, Tabontabon and Tunga.

The device relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimeter-level accuracy.

According to Joshua Navarro, the Technical Support of the Georight Matics Incorporated (GMI), this tool is linked with National Mapping and Resource Information Authority (NAMRIA), the central mapping agency of the Philippines, to ensure precision of the data.

He added that instead of radio device, the system could now easily be accessed 24/7 through internet or mobile data.

“The use of this device is just timely since the district office aims to fast-track numerous infrastructure projects under the “Build, Build, Build” program of the government,” District Engineer Gerald Pacanan said.
