SKA05M5040-30RSSJ is a quad-system, full-frequency measurement antenna supporting BeiDou B1, B2, and B3; GPS L1, L2, and L5; GLONASS G1 and G2; and Galileo E1, E2, E5a, E5b, and E6 signals. It is widely applicable in scenarios such as autonomous driving, geodetic surveying, ridge construction, marine surveying, and underwater topographic mapping. The antenna adopts a multi-feed design to ensure alignment between the phase center and geometric center, improving measurement accuracy. It integrates a low-noise amplification module and employs front-end and multi-stage filters to remove interference signals, ensuring reliable operation in harsh electromagnetic environments. Compact in size and lightweight in design.
