Helsinki - June 18th, 2025 - Duragon can now provide RTK navigation as an option across all device platforms. Routers with L1/L5 band navigation are available with RTK assisted DR-navigation. Inbuilt software manages server interfacing and delivery of correction data to the GNSS receiver. Centimeter-level accuracy can be achieven in areas where base station coverage is adequate. For defined areas such as depots or industrial sites, a small embedded base station is available. RTK assisted navigation elevates train and bus location to a new level. The concurrent use of L1/L5 bands improves vehicle location accuracy in dense urban locations.
