CW25 GPS receivers

NavSync Ltd has announced the release of two models in the CW25 series of GPS receivers. The CW25 GPS receiver modules are manufactured in a surface mount format (25-by-27-by-4mm), with an embeddable architecture that is designed to allow easy integration into host systems. This GPS family of receivers is well suited for applications that require indoor tracking, severe urban canyons, navigation, vehicle, asset and personnel tracking, security and surveying.

Receivers in the CW25 series are accurate to less than 5m in normal signal strength conditions. The base model in the series, CW25-NAV can track satellites down to signal levels as low as -157dBm and can acquire GPS lock at signals as low as -143dBm. This level of performance allows the CW25-NAV to maintain positional fixes in extremely weak GPS signal areas such as beneath thick foliage, dense urban canyons and even inside buildings.

Model CW25-ULS GPS receiver module has the same features as the CW25-NAV but with the additional ability to utilize network assist data to quickly lock in on satellites under very low signal levels (down to signal levels as low as -155dBm.) The network assist feature requires that the ephemeris data be uploaded from a central basestation located in the region. NavSync also produces the CW55 GPS basestation unit designed to provide the network assist data via the GPRS network to all CW25-ULS units located in the region.

The CW25-NAV is priced at Rs.1834 ($40) and the CW25-ULS is priced at Rs.2017.4 ($44) in 1,000-piece quantities. Both devices are already available.
