Software based GPS for Mobile Positioning - E5000 - CSR

CSR released it’s E5000 embedded mobile positioning software. E5000 will be showcased on advanced 3DLabs multimedia processor and the Samsung 2440 PND (personal navigation device) platform. CSR's GPS solution is software-based and requires no further hardware beyond a RF front-end. CSR provides the cost competitive, feature-rich GPS solution, enhanced tracking accuracy, allowing very short Time To First Fix ,  small footprint on PCB, and low power consumption.

E5000 replaces the conventional GPS baseband IC with software running on the embedded device’s application processor or DSP. E5000 software is compliant with most existing RF front-end chips supporting 1–4 bit sampling.

Matthew Phillips, CSR, said:

CSR's ability to offer the highest level of GPS capability at significantly lower cost with such small footprint and power requirements is of real advantage to our customers. These features make positioning viable in every mobile phone and other portable applications…
