Stacker is an important equipment for bulk cargo yard operations. The stacker is a machine that combines stacking and reclaiming, that is, a high-efficiency machine for digging and stacking loose materials such as coal, ore, sand and gravel.
Each stacker that needs to be positioned needs to be installed with a precision positioning and orientation differential receiver, the positioning accuracy is at the centimeter level, and the direction finding terminal is accurately positioned.
Through the dual-antenna positioning and direction finding GNSS receiver, the position, speed and heading information of the mobile carrier can be accurately determined, with centimeter-level positioning accuracy, and the data output frequency can reach 50Hz, with rich communication interfaces and stable performance.
A reference station receiver needs to be installed on a stable roof or bedrock. This reference station differential receiver is used as a reference system of known coordinates to provide corrected differential information for the mobile station receiver, so that the mobile station can achieve centimeter High-level precision positioning, differential data can be sent to the mobile station receiver through GPRS transmission mode, radio transmission mode or wired transmission mode.
It should be noted that when using GPRS differential mode, good mobile phone signal coverage is required on site, and a server computer and a fixed IP network need to be prepared; when using radio differential mode, both the mobile station and the reference station need to be equipped with high-power plug-in radios. Make sure the base and rover are visible.
