The iBase GNSS receiver is a fully integrated professional GNSS base station specifically designed to meet 95% of surveyors' needs when working in UHF GNSS base and rover mode. The performance of the iBase UHF base station compared to a standard external UHF radio modem is almost perfect. But its unique design eliminates the need for a heavy external battery, cumbersome cables, external radio, and radio antenna. Its 5-watt radio module provides operational GNSS RTK coverage up to 8 km and features a real-time UHF interference self-checking technique, allowing the operator to select the most appropriate frequency channel to use.
