Titan X1 - GNSS Antenna module for GPS, GLONASS, Galileo & QZSS applications

The Titan X1 from G Top is a multi-GNSS Patch Antenna module with simultaneous multi-constellation support, offering superior positioning accuracy and ultra fast time to first fix ( TTFF).

The Global Top Titan X1 is a state-of-the-art Multi-GNSS Patch antenna module in a compact footprint designed especially for applications where small size and easy integration are essential.

With its compact footprint of just 12.5mm x 12.5 mm, the Titan X1 is one of the smallest embedded patch antenna GNSS modules based on Mediatek's MT3333 chipset. It features an integrated, specially tuned (12mm x 12 mm) GPS and Glonass Patch Antenna that offers unparalleled performance for a module of its size.

Titan X1 offers a fully integrated design as standard, with a complete set of components including TCXO, RTC Crystal, SMPS, SAW Filter and an additional LNA; all considered vital for optimum performance.
