Using multi feed point design to ensure the superposition of phase center and geometrical center which could minimize the influence of measurement error to lowest range. Antenna unit gain is high, the direction of the beam width, to ensure that the low elevation signal to accept the effect, in some block more serious occasions can still receive satellite. With anti-multipath choke plate, effectively reduce the impact of multi-path on the measurement accuracy. With waterproof, anti-UV cover, for the antenna to provide long-term work in the field to provide protection. ■ Using multi feed point design to ensure the superposition of phase center and geometrical center which could minimize the influence of measurement error to lowest range. ■ Antenna unit gain is high, the direction of the beam width, to ensure that the low elevation signal to accept the effect, in some block more serious occasions can still receive satellite. ■ With anti-multipath choke plate, effectively reduce the impact of multi-path on the measurement accuracy. ■ With waterproof, anti-UV cover, for the antenna to provide long-term work in the field to provide protection.
