Taoglas GPDF5012.A Multiband GNSS Stacked Patch Antenna is a high-performance, passive GNSS antenna designed to provide positional accuracy on the full GNSS spectrum. It covers GPS/QZSS (L1/L2/L5), GLONASS (G1/G2/G3), Galileo (E1/E5a/E5b), BeiDou (B1/B2a/B2b), NAVIC (L5), as well as SBAS (WAAS/EGNOS/GAGAN/SDCM/SNAS). The GPDF5012.A allows users to achieve higher location accuracy, as well as stability of position tracking in urban environments. When used on the base and/or the rover as part of an RTK configuration, the GPDF5012.A can achieve genuine cm-level accuracy with proven results. The stacked patch construction provides excellent performance across the full bandwidth of the antenna. The component design has an even gain across the hemisphere, giving an excellent axial ratio, which in turn makes it extremely resilient to multipath rejection and provides excellent phase center stability.
