Design Smarter GNSS Systems with Taoglas: Precision Positioning, Timing & Interference Resilience

As demand grows for centimeter-level positioning, autonomous systems, precision agriculture, surveying, and intelligent transportation, GNSS designers require solutions that deliver both exceptional signal quality and simplified system integration. Taoglas addresses these requirements with the GPDF5012.A Multi-Band GNSS Antenna and the TFM.120A GNSS Front-End Module, a complementary pair designed to maximize the performance of modern multi-frequency GNSS receivers.

Advanced Multi-Band GNSS Positioning Solutions

Together, the GPDF5012.A and TFM.120A provide a complete signal acquisition and conditioning solution that helps designers achieve superior accuracy, increased reliability, and streamlined integration for next-generation positioning applications.

GPDF5012.A

Multiband High Precision GNSS Stacked Patch Antenna 50*50*12 mm

The Taoglas GPDF5012.A is a high performance, multi-band passive GNSS antenna that has been carefully designed to provide fantastic 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).

Correct implementation of the GPDF5012.A allows the user to achieve higher location accuracy, as well as stability of position tracking in urban environments. The stacked patch construction has excellent performance across the full bandwidth of the antenna. Its design has an even gain across the hemisphere, giving excellent axial ratio, which in turn makes it extremely resilient to multipath rejection and provides excellent phase centre stability.

TFM.120A

The Taoglas TFM.120A features a SAW/LNA/SAW/LNA topology in both the low and high band signal paths to prevent unwanted out-of-band interference from overdriving the GNSS LNAs or receiver. The SAW filters have been carefully selected and placed to provide excellent out-of-band rejection while also maintaining a low noise figure.
  • Superior Signal Quality – Integrated filtering and low-noise design minimize interference and optimize receiver performance.
  • Optimized Gain Architecture – Dual-stage amplification delivers strong GNSS signals without compromising signal integrity.
  • Compact Footprint – Low-profile design reduces board space and eliminates the need for external RF components.
  • Faster Time-to-Market – Expertly engineered, highly integrated solution that simplifies development and accelerates deployment.
