The XA1110 supports tracking of GPS+Glonass or GPS+Glonass+Galileo satellite system combinations to deliver superior positioning accuracy of <2.5m (with SBAS). Based on MediaTek’s latest MT3333 engine, it’s the smallest integrated antenna multi-GNSS module on the market with an ultra-compact form factor of 12.5 x 12.5 x 6.8 mm.
Unlike other compact GNSS modules, the XA1110 incorporates a complete set of high-quality components, including TCXO, RTC Crystal, SMPS, SAW Filter and an additional LNA, all of which are considered vital for optimum positioning performance.
The XA1110 offers flexibility with an external antenna interface that supports automatic antenna detection and selection. It also supports performance enhancing features such as EASYâ„¢ (self-generated orbit prediction), SBAS, AGPS (ephemeris file injection), LOCUSâ„¢ (internal logger), GLPâ„¢ (GNSS low-power) and PPS Sync.
Improve accuracy and time-to-fix with A-GPS, SBAS and EASYâ„¢
Active interference cancellation with automatic detection and removal
Reduce active tracking power consumption by up to 50% with GLPâ„¢
15+ SDK commands to change default GNSS behavior and enable extended features
Built-in RTC Crystal, TCXO, SMPS, additional LNA and additional SAW-filter for best-in-class performance
Integrated patch antenna with automatic antenna switching
Tested for harsh environments and extreme temperatures
Option of using I2C or SPI instead for UART for communication and control
