Ct-G550 of products utilizes SiRFstarV⢠and features Quad-GNSS for tracking GPS, GLONASS, BDS and Galileo satellites. The product family deliver 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 then 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.
