Jun 23, 2009 Suited for makers of high-volume navigation and location devices, SiRFatlasIV® employs 64-channel, multi-satellite system location engine, with 1,000,000+ correlators, that optimizes TTFF and provides -161 dBm simultaneous tracking of GPS and Galileo satellites. Integral 500 MHz ARM11 processor core, with vector floating point unit, is complimented by 64-bit system bus and high-speed memory controller with DDR 400/Mobile-DDR 333 memory module support.

GPS Software eliminates PND start-up wait.

SiRF Technology, Inc.    San Jose, CA 95112
Jan 14, 2008 Available for SiRFstarIII GPS receivers and SiRFatlas and SiRFtitan SoC navigation processors, SiRFInstantFixII achieves GPS start-up in as little as 5 sec. Algorithms enable portable navigation device to model behavior of visible GPS satellites during day and predict position in sky for up to 3 days in future. Without updates from network, SiRFInstantFixII continuously refines calculations based on latest data it receives from satellites being tracked every time PND is used.

GIS Software combines GPS with dead-reckoning.

SiRF Technology, Inc.    San Jose, CA 95112
Jul 26, 2007 Employing algorithms that utilize closely coupled GPS and dead-reckoning sensor measurements, SiRFDiRect(TM) delivers accurate positioning, even if GPS signals are weak or blocked such as in dense urban canyons and tunnels. Combining SiRFstarIII® architecture with heading and acceleration sensors, it offers in-dash vehicle positioning quality in portable navigation devices. Software allows flexibility in orienting portable navigation devices when mounting them in vehicle.

Signal Processor brings GPS capability to mobile devices.

Feb 20, 2007 Measuring less than 10 mm², SiRFstarIII GSD3t combines RF, analog, and signal processing in 90 nm RFCMOS die. Unit delivers -160 dBm signal acquisition in AGPS mode and better than -160 dBm signal tracking to provide location data in harsh outdoor conditions and many indoor locations. SiRFNav® software supports autonomous GPS navigation, Multimode Aided-GPS navigation, and SiRFInstantFix(TM) service, which minimizes start-up wait time for GPS systems.

A-GPS Chip addresses space constraints of cell phones.

SiRF Technology, Inc.    San Jose, CA 95112
Feb 23, 2006 Housed in 2 x 6 x 1.0 mm, 77-pin BGA chip, ROM-based GSCi-5000 Receiver utilizes 90 nm CMOS and 0.18 micron SiGe process technologies. It features integrated low noise amplifier, fractional synthesizer, and technology that minimizes impact of RF jamming and compression issues. Compliant with 3GPP requirements, unit supports Mobile Station-based, MS-assisted, autonomous, and multimode operation. Power consumption is minimized using self-managed periodic fix modes and 5 µA sleep mode.

GPS Chips extend battery life of navigation devices.

SiRF Technology, Inc.    San Jose, CA 95112
Feb 23, 2006 Utilizing 90 nm CMOS, 0.25 micron BiCMOS process technologies, SiRFstarIII-LT GSC3LT and GSC3LTi provide position, speed, heading, and time information. Housed in 7 x 7 x 1.2 mm, 153-pin BGA chip, Model GSC3LT includes self-sufficient power management, power-on reset circuitry, low noise amplifier control, and TCXO voltage supply and control. Model GSC3LTi is packaged in 6 x 6 x 1.2 mm, 120-pin BGA chip, and is suited for handheld systems that have centralized power management.

GPS Chipset integrates total functionality in one package.

SiRF Technology, Inc.    San Jose, CA 95112
Dec 19, 2005 SiRFstarIIx chipsets are available in GSC2x, GSC2xr, and GSC2xrx versions that integrate RF and baseband into one package; models GSC2xr and GSC2xrx also eliminate need for external flash memory. Measuring 10 x 7 mm, single-chip solutions require 60 mW power for nominal operation and 25 mW for TricklePower operation. Internal software allows use of various configurations from blinking LEDs and varying baud rates and protocols.
