Dated: July 10, 2009
1 General Description
This specification provides a general guideline on the performance and the integration of the Wi2Wi, Inc.
NAVSTAR L1C/A Band, 20 Channel GPS Receiver Module Solution. The solder-down module, Part Number
W2SG0006, is targeted to assist companies to easily integrate GPS functionally into their products. This is
accomplished by reducing their development times and cost by using a complete, small form factor, low power,
ready to integrate GPS Receiver System Solution.
The specification maximum and minimum limits presented herein are those guaranteed when the unit is integrated
into the Wi2Wi, Inc. W2SG0006-DEV Development System. These limits are to serve as the representative
performance characteristics of the W2SG0006 when properly designed into a customer’s product. Wi2Wi makes
no warranty, implied or otherwise specified, with respect to the customer’s design and the performance
characteristics presented in this specification.
2 Features
The Wi2Wi W2SG0006 is a 20 Channel Global Position System (GPS) receiver surface mount device (SMD)
solution. Based upon the SiRFstar III™ technology, the SMD features fast acquisition times, high receiver
sensitivity and low power consumption in a small, compact form factor. The W2SG0006 is a flexible design that
supports a broad range of applications where GPS functionality and location based services is required.
Key features of the W2SG0006 are as follows:
GPS technology based upon by the SiRF Technologies™ SiRFStar III™ LPx device
Compact design for easy integration: 15mm x 15mm x 2.5mm (including shield)
Fast acquisition time and high sensitivity GPS Receiver
Ultra-low power consumption.
Surface Mount Design (SMD)
50Ω Antenna Launch
20 channel GPS receiver
Multi-path Mitigation
Uses NAVSTAR GPS L1 C/A signal
SBAS (WAAS, ENGOS and MSAS) support
Single 3.3 VDC supply input
Two Configurable UART Interfaces
Available Software accelerator for improved sensitivity: Satellite acquisition and tracking
Format Selectable Output Data: NMEA, SiRFBinary™ and AI3/F
Compatible with SiRF Technologies GSW3 Software
RoHS Compliant
