Ct-G551 3.3V 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. Performance - GPS, GLONASS, Galileo, BDS and SBAS reception for high GNSS availability and accuracy - High sensitivity navigation engine (PVT) tracks as low as : - GPS : -165 dBm - GLONASS : -161 dBm - 52 track verification channels - SBAS (WAAS or EGNOS,MSAS) - Active Jammer Remover, removes in-band jammers up to 80 dB-Hz - Tracks up to 8 CW jammers - Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted), need operator support. - Embedded CGEE / SGEE (With back-end server support) speed up TTFF a lot and makes cold start time to be around 20+ seconds. - SiRFGeoRecovTM Reverse EE makes positioning process being done under power saving mode. - Reacquisition Time : 0.1 second - RF Metal Shield for best performance in noisy environments
