CSR , a leading provider of GPS-powered location platforms, has launched its breakthrough SiRFstarIV location-aware architecture with exclusive SiRFaware self-assisted, micro-power GPS technology that enables consumer devices to always be location aware – without draining batteries and without requiring network aiding.
CSR also introduced its first SiRFstarIV-based product, the GSD4t receiver, which offers a superior solution for enabling mobile phones and other space- and power-constrained devices to have the robust, always-available geo-awareness consumers are demanding.
The essence of the SiRFstarIV breakthrough is its ability to continually maintain “better-than-hot-start” conditions in the GPS receiver for fast location fixes without having to be kept fully turned on all the time and draining precious battery power.
Until now, designers of mobile devices were forced to completely turn off GPS receivers when not in use to conserve power, causing annoying start-up delays when a location application needed to get a new location fix quickly. Through a fusion of multiple innovations, the unique SiRFaware technology overcomes this barrier with or without network aiding while consuming only 50-500 microamperes of current.
