Real Time Kinematic (RTK) satellite navigation is a technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems, GNSS) such as GPS. A Continuously Operating Reference Station (CORS) network is a network of RTK base stations that broadcast corrections, usually over an Internet connection. Accuracy is increased in a CORS network, because more than one station helps ensure correct positioning and guards against a false initialization of a single base station. GNSS satellite observations are continuously gathered from all the reference stations and streamed to a central processing center (i.e. TopNet) via the Internet. All the observations are then used to model the entire network.
MANY NETWORK RTK SUBSCRIPTION SERVICES EXIST TODAY. ADVANTAGES OF THESE NETWORKS INCLUDE:
• Minimizes distance dependent errors
• Quickly setup and start
• No need to purchase or move a base station
• Increased productivity using a network vs traditional base and rover
• All users use a common coordinate system
TopNet Live is fully operable with all makes of network capable rovers. RTK solutions allow an operator to have complete control and management through all stages of the crop development process. These solutions help boost an operators efficiency, accuracy and are most importantly, easy to use.
