GA8112 high-precision measurement antenna can receive GPS L1 / L2 / L5, BDS
B1 / B2 / B3, GLONASS L1 / L2, and GALILEO E1 / E2 / E5a / E5b frequencies have good
low-elevation gain, wide-angle circular polarization, and stable phase center. It is
applicable to the field of multi-system and high-precision surveying and mapping, and is
widely used in geodetic surveying, road construction, marine surveying, and terminal
container operations.
GA8112 antenna part adopts a multi-feedpoint design scheme to ensure the coincidence
of the phase center and the geometric center, and the influence of the antenna on the
measurement error is minimized;
GA8112 antenna unit has high gain and directional pattern beam width to ensure the
low-elevation signal reception effect, and it can still search for stars in some occasions
with severe obstruction.
