Ct-G340 S5 of products utilizes SiRFstarV ™ and featuresQuad-GNSS for tracking GPS, GLONASS, BDS and Galileo satellites.The product family deliver highly accurate continuous location,advanced power management and high interference immunity. Thesecontinue to push the envelope of performance in sensitivity, TTFFand urban canyon availability and accuracy. With a built-in DSPand extremely low power consumption, the family can get fastlocation fixes for geo-tagging images or videos, asset trackingand wearable applications.
Advanced low power technology means there is no need to maintainfull power to achieve maximum performance nor turning the GNSSreceiver completely off to save power. It breaks then old GNSSperformance vs. power trade-off through the fusion of a newhigh-performance GNSS engine, advanced power management and asmart sensor interface to achieve high sensitivity hot-startconditions for fast location fixes.
