La description

The DS***3  utilized SiRF V and features 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.

Performance
- GPS, GLONASS, Galileo and SBAS reception for high GNSS availability and accuracy
