Introduction
GAU (Guowei Acquisition Unit) is Guowei's newly launched innovative instrument. Supporting external 4G antennas and various geophone models, it delivers high-speed, stable data transmission even in extreme environments with weak 4G signals. The external power supply design further enhances stability and durability. Deployed primarily in densely forested areas with weak ground-level 4G signals and in downhole fracturing monitoring, it plays a critical role in enhancing signal stability and improving subsurface data acquisition quality.
