This specification provides a general guideline on the performance and the integration of the Wi2Wi,
Inc. NAVSTAR L1C/A Band, 48 Channel GPS Receiver Module Solution. The solder-down module,
W2SG0084i which is a drop in replacement for the W2SG0004, 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. Development System. These limits are to serve as the representative
performance characteristics of the 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.
