South has redesigned the receiver, incorporating a conspicuous yellow bodywork based on user feedback to enhance visibility for surveyors and instruments in diverse environments. Whether on a construction site or in dense forests, the G4 users’ improved visibility promotes safety. In challenging conditions like forests or at night, the receiver’s working status is now more clearly visible from a distance. The SOUTH research team’s advanced technologies, such as the SOUTH algorithm, ensure accurate data correction in harsh environments. The fixed-keep feature allows continuous measurement for a few minutes after losing the fixed solution. Leveraging Beidou PPP and Galileo HAS, it’s technology enables precise point positioning via satellite signals, even in CORS-correction-absent areas.
