The Toknav T50Basic is a palm-sized RTK GNSS rover (roughly 132x83mm, 770g) built on a 1408-channel full-constellation engine (GPS, GLONASS, BDS, Galileo, QZSS, SBAS). It includes a built-in IMU for tilt-compensated measurement up to roughly 60 degrees of tilt, an ultra-wide-angle camera for AR-assisted stakeout, and onboard 4G, Bluetooth, WiFi and LoRa (up to ~15km) radio connectivity, with IP68 sealing, 32GB storage, and about 16 hours of battery life.
