Low-power and high-precision、 ultimate precision to 0.6 meters. The actual test mostly about 0.9 meters. Pix to test the accuracy of the return is mostly in between 20-30cm、relative to the previous generation of NEO-7N 1.3-1.6 meter accuracy to improve a lot.     2. The star search speed and volume improved significantly、 to support Europe's Galileo、 Russia's GLONASS、 Japanese QZSS、 Chinese BeiDou.     3. The module supports GPS + Compass + SBAS or GPS + GLONASS + SBAS. This version is built-in electronic compass、 the refresh rate to 18Hz.
