Integrated Antenna GNSS
Constellations: GPS+BeiDou
Interfaces: UART,SPI,I2C
Form Factor: GNSS with Antenna

AirPrime® XA1120 GPS+BeiDou Module with Patch Antenna

Compact, high-precision GPS+BeiDou positioning with integrated antenna

The XA1120 tracks both GPS and BeiDou constellations simultaneously to deliver superior positioning accuracy of <2.5m (with SBAS). Based on MediaTek’s latest MT3333 engine, it’s the smallest integrated antenna GPS and BeiDou module on the market with an ultra-compact form factor of 12.5 x 12.5 x 6.8mm.

Unlike other compact GNSS modules, the XA1120 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 XA1120 offers flexibility with an external antenna interface that supports automatic antenna detection and selection. It also supports performance enhancing features such as EASY™ (self-generated orbit prediction), SBAS, AGPS (ephemeris file injection), LOCUS™ (internal logger), GLP™ (GNSS low-power) and PPS Sync.
