CSR, a provider of GPS-powered location platforms, has released its SiRFstarIV location-aware architecture with SiRFaware self-assisted GPS technology that reportedly enables consumer devices to always be location aware without the requirement of network aiding.
According to CSR, the SiRFstarIV architecture core comes with a GPS location engine, location sensor interface, adaptive micro-power manager and active jammer remover. The new architecture comes with DSP technology, which searches for jammers and removes them prior to correlation to enhance GPS performance and design troubleshooting.
CSR also unveiled its new SiRFstarIV-based product, the GSD4t receiver, which offers mobile phones and other space- and power-constrained devices to have the geo-awareness.
The company said that the new GSD4t receiver provides enhanced performance, with navigation to -160 dBm, tracking to -163 dBm and pass margins for E911 and 3GPP. It is also expected to maintain its full rated -160-dBm acquisition sensitivity without network assistance.
In addition, the SiRFstarIV-based GSD4t features include, active jamming removal, single-SAW design, an on-chip LNA, fail-safe I/O, integrated switchers and single supply voltage.
Kanwar Chadha, chief marketing officer of CSR and founder of SiRF, said: With consumers expecting reliable location services everywhere, we had to rewrite the traditional rule book on GPS architectures and create a new, low-energy way to maintain continuous location awareness without draining the device battery or requiring network assistance.
“With SiRFstarIV and our unique SiRFaware technology, we have developed an architecture that will not only significantly improve the consumer experience when navigating with smartphones, but also enable consumer devices to maintain continuous location awareness.”
