After careful selection by the China maritime surveillance detachment, the 1.8m C-band shipborne Zhongtong of Dashun weir company was selected. Finally, the product was equipped on a marine surveillance ship of a Chinese maritime police department and was highly praised by the superior leaders. This system has strict requirements on the accuracy of antenna to satellite performance, and also has high requirements on the anti wind and wave performance and protection grade of the whole dynamic communication system. The successful system implementation fully shows the long-term accumulation and progress of our company. I would like to thank all departments for their strong cooperation in this project and hope that all departments will make persistent efforts and make greater progress.
