South Korea's New GPS Service, G-VRS, Promises Centimeter-Level Accuracy Offline
South Korea is rolling out a new GPS-based positioning service, Gridded Virtual Reference Station (G-VRS), with a test operation set for October. The service promises centimeter-level accuracy even in areas with poor internet connectivity.
GNSS control points have been installed across South Korea, including Jeju Island and Gageodo, with plans to expand to Ulleungdo Island by the end of the year. G-VRS complements existing VRS systems, which rely on internet access for improved location accuracy.
The test service, starting in October, will accommodate up to 300 participants. Details will be available on the NGII homepage from Wednesday. Unlike traditional GPS devices, G-VRS provides real-time location data with centimeter-level precision without an internet connection. This makes it ideal for remote areas with weak or unstable connections, such as islands, mountains, or fast-moving vehicles.
Potential applications of G-VRS are vast. It could revolutionize drone-based delivery and pest control services, or even automated driving. The G-VRS system has proven its accuracy in real-world environments, matching the precision of existing VRS systems.
South Korea's launch of the G-VRS test operation in October brings a new era of precise GPS positioning, even in challenging terrains and connectivity conditions. This could open up new possibilities for various industries, from logistics to autonomous vehicles.
