The Toknav T50Pro is a palm-sized GNSS RTK receiver (roughly 132x83mm, 770g, IP68) that tracks multi-frequency signals across GPS, GLONASS, BDS, Galileo, QZSS and SBAS/IRNSS on 1408 channels. It combines a built-in high-precision IMU with photogrammetry and AR stakeout functions for tilt-compensated field surveying, and connects via 4G, Bluetooth, WiFi, integrated LoRa radio (up to 15km) and NFC. It runs Linux with 8GB onboard storage and roughly 16 hours of battery life.
