The Sierra Wireless 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 EASY™
(self-generated orbit prediction), SBAS, AGPS (ephemeris file
injection), LOCUS™ (internal logger), GLP™ (GNSS low-power) and PPS
Sync.
Benefits:
- Improve accuracy and time-to-fix with A-GPS, SBAS and
EASY™
- Active interference cancellation with automatic detection
and removal
- Reduce active tracking power consumption by up to
50% with GLP™
- 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

This development kit is designed to help you
evaluate the GNSS module features such as TTFF, position accuracy,
and various GNSS commands. The kit uses a single USB interface for
both power supply and communication. It also comes with an external
antenna attachment and dedicated LEDs for 3D-Fix and
1PPS.
