Alpha 5W Long-range RTK

Alpha 5W has a built-in 5 W transceiver radio, fully compatible with the main RTK protocols on the market, plus a low-power LoRa mode. Range reaches up to 8 km in ideal conditions and 5 km in urban environments; as a LoRa base station, according to the 2026 catalog, up to 12 km. It supports the full 410–470 MHz band and has a serial port for external radios.

The calibration-free IMU with temperature compensation needs no initialization: after a few steps it enters inertial navigation, with 2 cm accuracy at a 60° tilt, 90° point measurement and, under good satellite conditions, short-term measurement up to 120°. PPP converges in about ten minutes.

With onboard 4G, satellite-based corrections and Dimap Pro software, the 5W handles demanding survey scenarios. The battery lasts up to 40 hours as a rover with smart power supply, and it can also be powered from a power bank.
