Applications
It is widely used
in high-precision navigation, aerospace, precision agriculture, vehicle
positioning, UAV and other high-precision navigation and positioning occasions.
KeyFeatures
uMulti feed point technology is adopted to
ensure the performance of right-handed circular polarization and phase center, and reduce the influence of measurement error;
nTheantenna unit has high passive gain and wide pattern beam to ensure the reception effect of low elevation signal;
nPre filtering, low noise coefficient and strong anti-interference ability.
