Can weaken GNSS observation pier of multipath effect

The utility model discloses a can weaken GNSS observation pier of multipath effect, including the observation pier main part and lieing in the antenna house tray of observing in the mound main part, antenna house tray top is equipped with GNSS antenna and antenna connection head, and the GNSS antenna is equipped with the collar that presses down that can shelter from GNSS antenna downside outward,is equipped with the antenna house above the outside of antenna house tray. The utility model has the beneficial effects of the navigation letter is received to the GNSS antenna, realizes satellite navigation, block through pressing down the collar that weakening comes from the multipath signal of ground and low elevation diffuser, improves GNSS antenna precise guidance's ability, simple manufacture, low cost, press down collar height -adjustable, observation pier can adapt to different topography, and the universality is high. 本实用新型公开了种可削弱多路径效应的GNSS观测墩，包括观测墩主体和位于观察墩主体上的天线罩托盘，天线罩托盘上方设有GNSS天线和天线连接头，GNSS天线外设有可遮挡GNSS天线下
