The Here 4 Base, a product of CubePilot, is compatible with both Ardupilot and PX4 systems. It also seamlessly interfaces with ground control stations, including Mission Planner and QGroundControl. Employing RTK (Real-Time Kinematic) technology offers more precise position estimation compared to standard GNSS systems. Its potential for centimeter-level accuracy greatly enhances flight precision. Furthermore, the Here 4 Base is designed for user-friendliness. Setting it up to work with Mission Planner is a straightforward process, requiring minimal configuration. For data communication between rover and base modules, a pair of telemetry modules is required (please note that these modules are not included in the standard package).
