Septentrio AsteRx-i3 D Pro GNSS/INS Receiver: Unmanned Agricultural Machinery
High-precision GNSS/INS positioning and attitude sensing are essential for unmanned agricultural machinery to achieve centimeter-level straight-line driving, precise headland turns, slope adaptation, and all-weather operation. The Septentrio AsteRx-i3 D Pro is a compact, single-antenna GNSS/INS receiver delivering centimeter-level RTK positioning (0.6 cm + 0.5 ppm) and high-precision 3D attitude (0.2° heading, 0.02° pitch/roll).
