Taoglas GPDF254.A Passive Dual Pin GNSS Patch Antenna is a high-performance, single-band passive GNSS L1 antenna designed to provide positional accuracy on the full GNSS L1 spectrum. The component features a dual-feed, passive patch design which makes it ideal for next-generation GNSS devices that require excellent positional accuracy in a small form factor. The patch antenna, by means of a double resonance design, offers a wide-band operation over GNSS systems including GPS (L1), GLONASS (G1), Galileo (E1), and BeiDou(B1). The 25mm patch uses a dual-feed configuration to obtain an optimal axial ratio. When used on the base and/or the rover as part of an RTK configuration, the GPDF254.A can achieve genuine cm-level accuracy with proven results. The GPDF254.A is manufactured and tested in a TS16949 first-tier automotive-approved facility.
