|
|
| |
 |
|
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.
