控制测量用静态GNSS接收机
Control networks are built from hours of static observation, and a receiver for that job needs long battery life and clean raw data. This 800-channel unit reaches 2.5 mm + 0.5 ppm horizontal accuracy, logs at up to 20 Hz to 16 GB of storage and exports RINEX 3.x. One battery covers about 24 h.
