The P-Box-X7 UAV positioning terminal is a compact, high-speed solution developed for full-system, multi-frequency, high-precision positioning and orientation. Supporting BDS-2, BDS-3, GPS, GLONASS, Galileo, IRNSS, SBAS, and QZSS signal tracking, it integrates an onboard IMU for enhanced navigation. With its mini size, low weight, and low power design, the P-Box-X7 is ideal for UAVs, autonomous robots, and other applications requiring strict SWaP performance.
