The W2SG0084i is designed for connection to either a passive or active antenna. The GPS module
includes an internal LNA and is designed to work with the passive antenna, but provides the bias
voltage supply for an active antenna to improve the receive sensitivity. If the design is to work with an
Active Antenna; Pin 20 (3V3_ANT) is tied to 3.3VDC.

The W2SG0084i device is embedded with GPS software. This software is optimized to work
in very weak signal environments to improve navigation availability and accuracy.
To enable GPS performance testing, Wi2Wi provides a W2SG0084i GPS Evaluation board,
along with the SiRFLive 2.2 software tools.
The SiRFLive 2.2 is a PC tool that provides real-time monitoring of an attached GPS
receiver’s operation such as satellites being tracked, observed signal strength, and current
position.
