Description
CSR’s next generation SiRFstarV™ family of products feature Quad-GNSS for tracking GPS, GLONASS, COMPASS,
and Galileo satellites. The SiRFstarV chips deliver highly accurate continuous location, advanced power management
and high interference immunity. SiRFstarV continues to push the envelope of performance in sensitivity, TTFF, and urban
canyon availability and accuracy. With a built-in DSP and extremely low power consumption, the SiRFstarV™ 5e can get
fast location fixes for geo-tagging images or videos, asset tracking and fitness applications.

Highlighted Advantages
Advanced low power technology means never having to maintain
full power to achieve maximum performance nor turning the GNSS
receiver completely off to save power. It breaks the old GNSS
performance vs. power trade-off through the fusion of a new highperformance GNSS engine, advanced power management, and a
smart sensor interface to achieve high sensitivity hot-start conditions
for fast location fixes.
Special power modes (Push-to-Fix) ideally suited for camera and
asset tracker use cases. Push-to-Fix is an intelligent periodic low
power mode that can adaptively change power depending on the
environment and motion conditions. Advanced algorithms and a
powerful on chip DSP processor maintain a high accuracy (QoS)
while achieving the lowest power level possible for the given
environmental and motion conditions. Data logging can be achieved
with a very low energy-per-fix and completely independent of the
host processor, which could be powered off.
Dynamic contextual awareness, temperature monitoring, and MEMS
sensors work in concert to conserve power and boost performance.
This opens up a wide variety of use cases for sports camera, asset
tracking and fitness devices.
Premium on-chip software provides a new level of continuous location
awareness by employing the following advanced technology:
„„ Advanced power management allow the GNSS receiver to stay
in a hot-start condition nearly continuously while consuming
very little power
„„ Local or server generated ephemeris prediction, capturing
ephemerides, and predicting them three days to one month in
advance boosts sensitivity and performance
