GPDF254.A – Passive Dual Pin GNSS Patch Antenna 25*25*4 mm


Passive Dual Pin GNSS Patch Antenna

The GPDF254.A is a high performance, single-band passive GNSS L1 antenna that has been carefully designed to provide fantastic positional accuracy on the full GNSS L1 spectrum. It has 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, has a wide-band operation over GNSS systems including GPS (L1), GLONASS (G1), Galileo (E1) and BeiDou(B1). The 25 mm patch uses a dual-feed configuration to obtain an optimal axial ratio. The GPDF254.A is manufactured and tested in a TS16949 first tier automotive approved facility.

Typical applications include:
• High accuracy positioning and navigation systems
• UAVs, Robotics & Autonomous Vehicles
• Transportation & Telematics
• Precision Agriculture
• RTK Systems

The GPDF254.A is the latest embedded addition to Taoglas’ product portfolio of high precision GNSS antennas. 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.

Full integration guidelines are contained in Section 8 of this datasheet including the Taoglas HC125.A hybrid coupler that will be required for use for dual pin feed patch integrations. Two active versions of this antenna, the ADFGP.25A.07.0100C – tuned for a 70*70mm Ground Plane and ADFGP.25E.07.0100C – tuned for free space is available and supplied with 100mm cable and I-PEX MHFI connector as standard.
