Positioning RTK, or Real-Time Kinematics, is a long-established technology that improves the positioning provided by a GNSS mobile receiver, based on a network of fixed reference receiver antenna, precisely positioned over the territory. Although highly effective, this solution is still very costly and therefore not available to all users. The emergence of low-cost electronic products has given rise to the CentipedeRTK network. The network is based on an open and shared methodology for building RTK antennas that are networked for free and collaborative use, whatever their purpose. Since its launch in 2019, the network has gone from strength to strength, and its uses are multiplying in a variety of fields, from forestry research to environmental monitoring.
