Alpha XBase RTK Super Base Station

Alpha XBase is Alpha Surveying's most capable RTK base station. Its built-in 7 W dual-mode radio uses Alpha's proprietary Di-Link protocol, globally compatible protocols and LoRa mode. In real-world tests, the typical range is about 20 km in towns, 30 km in open areas and 10 km in dense urban environments. The high-gain pole antenna improves signal gain by around 50%.

Two hot-swappable battery packs (2 × 95 Wh) allow the radio to transmit continuously for up to 15 hours, while static operation exceeds 80 hours. At −30 °C it transmits for more than 10 hours. The "hamburger" thermal design keeps the transmission range stable during long continuous operation.

The built-in GNSS antenna supports 7 satellite constellations, L-band and BeiDou and Galileo satellite-based correction services, delivering centimetre-level RTK even without control points or network coverage. With onboard 4G it can serve as a compact CORS station or as a base for agriculture, machine control, drones and unmanned systems. It also includes an IMU, base movement alerts and a 5-pin port for external power, and the battery packs can be used as power banks.
