The National Geographic Information Institute, an affiliate of the Ministry of Land, Infrastructure and Transport, on Sept. 30 announced its launch next month of trial operations of the Gridded-Virtual Reference Station (G-VRS), a location data service based on a new satellite.

The G-VRS supports precise position measurements accurate within cm even without an internet connection. It requires only broadcast signals to receive information on position corrections and is thus usable in regions with unstable web connections such as mountains and islands.

The technology is usable in diverse formats like digital multimedia broadcasting with fewer interruptions.

"G-VRS will be usable with drones for delivery, agricultural pest control and self-driving using GNSS (global navigation satellite system) location correction data," the ministry said. "Users can receive corrected information by selecting the nearest grid without the need to send location data separately."
