Autonomní Accessories RA100 AiCRTK Reference Antenna Cramer developed its Cramer RTK Fusion™ technology to combine data from satellite, radar, camera and additional onboard sensors for centimeter accurate positioning through the reference antenna. RA100 Accessories Tech Spec The reference antenna receives satellite signals and sends correction data to the mower to achieve positioning with cm accuracy. The data is communicated from the reference antenna to the mower via LoRa (Long Range). Multiple AiConic mowers can connect to one reference antenna simultaneously, meaning that if terrain and infrastructure allow, one site with several mowers operating only need one reference antenna. A mounting bracket is included in the package, making it easy to mount the antenna directly to a flat surface, or to a pole with diameter between 32 mm and 50 mm.
