4 Development Support
The W2SG0006 device is embedded with GPS software, GSW3. 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 W2SG0006 GPS Evaluation board, along with
the SiRFDemo software tools.
The SiRFDemo 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. It also provides the ability
to configure the receiver for specific operating modes, as well as a data logging ability for later
investigation
