2 PRODUCT DESCRIPTION
The SE868Kx-A GNSS antenna module family provides complete multi-constellation position,
velocity, and time (PVT) engines featuring high performance, high sensitivity, and low power
consumption.
The inclusion of the GLONASS constellation (on selected models) yields better coverage,
greater accuracy, and improved availability.
These modules include a built-in SMT patch antenna
These modules are based on the MediaTek MT3333 (SE868-A and SE868K3-A/AL)
series) or MT3337 (SE868-AS and SE868K7-A/AL) chipset.
