The BY403 antenna is capable of simultaneously receiving signals from GPS L1/L2/L5 and BDS B1/B2/B3, GLONASS G1/G2 frequency bands, featuring high peak gain, good low elevation gain, wide-angle circular polarization, and a stable phase center. It is suitable for high-precision surveying and widely used in geodetic surveying, road construction, marine surveying, port container operations, border surveillance, and other scenarios.
Features
- The antenna part adopts a multi-feedpoint design scheme to ensure the coincidence of the phase center with the geometric center, minimizing the impact of the antenna on measurement errors.
- The antenna unit has high gain, and the radiation pattern has a wide beam, ensuring the reception of low-elevation signals. It can still operate normally in environments with significant obstructions.
