CW25-NAV CW25-NAV GPS Receiver P R O D U C T B R I E Description The CW25-NAV CW25-NAV is a small OEM surface mount GPS module that has been specifically designed for extremely high sensitivity for use in very weak GPS signal environments. The CW25-NAV CW25-NAV can acquire and track satellites down to signal levels as low as 155dBm (and can autonomously acquire satellites down to signal levels as low as 143dBm), while still maintaining TTFF performance of under 2 seconds outdoors and under 5 seconds indoors. The CW25-NAV CW25-NAV achieves this level of performance by using a high performance baseband processor that can search in parallel 12288 time/frequency bins. This level of performance allows the CW25-NAV CW25-NAV to obtain rapid positional fixes in extremely weak GPS signal areas such as under dense foliage, dense urban canyons and even inside buildings. The CW25-NAV CW25-NAV is an exceptionally small surface mount package (25mm x 27mm x 4mm) with a highly integrated architecture that requires minimal external components, allowing easy integration into host systems.
