The quad-GNSS SiRFstarV 5t tracker from CSR plc is the first SiRFstarV device to offer exclusive CSR adaptive continuous tracking power management technology, which offers significant power savings for extended battery life, and also includes MEMS inputs, LTE immunity, enhanced active jammer removal and other SiRFstarV advantages. The SiRFstarV 5t is already in use by LG Electronics for its first quad-core smartphone, the LG Optimus 4X HD, which takes advantage of the device’s GLONASS support and high sensitivity.
Optimized for Mobile Platforms: Optimised for size- and power-constrained applications, the SiRFstarV 5t boasts a number of enhanced SiRFstarV architectural features – from quad-GNSS support and MEMS-aiding, to improved sensitivity and interference rejection to small size and low BOM count – that result in significant location performance and power consumption improvements, reduced package size, easier integration and lower-cost implementation. The SiRFstarV 5t supports A-GPS and A-GLONASS in MSA and MSB modes, and has been tested for all major carrier requirements, including SUPL1.0 and SUPL2.0, and offers improved 3GPP acquisition and tracking margins. SiRFInstantFix extended ephemeris technology for GPS and GLONASS is also supported.
The SiRFstarV 5t supports all four major global navigation satellite systems (GNSS). With its 24 additional satellites, GLONASS provides a valuable augmentation to GPS and enables the SiRFstarV 5t to boost location performance, especially in urban canyons, for the most demanding applications by increasing service availability, reducing observation time and making solutions more precise. The SiRFstarV 5t additionally supports Galileo and Compass systems, when they become available, with a software upgrade for even greater performance and ensured compliance to existing and future requirements of the world’s major GNSS systems.
The SiRFstarV 5t introduces CSR’s exclusive TricklePowerII technology, an improved intelligent power management system that can deliver significant power savings compared to other location solutions for continuous 1-Hz navigation. TricklePowerII continually measures the strength of the available satellite signals and dynamically adjusts the chip’s power consumption to just the right amount to achieve optimal location performance without wasting power.
The SiRFstarV 5t quad-GNSS tracker product (part number: CSRG05TA03-ICJE-R) is available now in production quantities.
