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

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

The Global Top, FireFly X1 GPS module combines miniature size with flexible multi-interface connectivity options such s SPI and I²C, that can simplify a user's design, making it ideal for M2M applications that typically use low-cost micro processors with limited serial interfaces.

The FireFly X1 module utilizes MediaTek's new generation MT3333 GNSS chipset and supports various location and navigation applications including autonomous GPS, GLONSS, GALILEO, QZSS, SBAS, DGPS (RTCM) and AGPS. The FireFly X1 supports up to 210 PRN channels with 99 search channels and 33 simultaneous tracking channels.

The MT3333 chipset has the industry's highest level of sensitivity (-165dBm) as well as instant Time-to-First Fix (TTFF). It also combines many advanced features including AlwaysLocate™, EASY™, EPO™ and logger function.
