Ct-GM551 of products
utilizes SiRFstarV and feature Quad-GNSS for tracking GPS,
GLONASS, BDS and Galileo satellites. The product family delivers
highly accurate continuous location, advanced power management
and high interference immunity. These continue 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 family can get fast location
fixes for geo-tagging images or videos, asset tracking and
wearable applications.
Advanced
low power technology means there is no need to maintain full
power to achieve maximum performance nor turning the GNSS
receiver completely off to save power. It breaks old GNSS
performance vs. power trade-off through the fusion of a new
high-performance 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
tracking 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
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
power 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 allows GNSS receivers to stay in a
hot-start condition nearly continuously while consuming very
little power.
*
Local or server generated ephemeris prediction, from three days
to one month in advance to boost sensitivity and
performance.
