All of Freematics products involving GNSS have shifted to u-blox M10 solution which has better position accuracy (1.5m) and lower power consumption comparing to previous M8 solution.

From the datasheet:

The u-blox M10 supports concurrent reception of four GNSS (GPS, GLONASS, Galileo, and BeiDou). The
high number of visible satellites enables the receiver to select the best signals. This maximizes the
position availability, in particular under challenging conditions such as in deep urban canyons. u-blox
Super-S (Super-Signal) technology offers great RF sensitivity and can improve the dynamic position
accuracy with small antennas or in non-line-of-sight scenarios.
The extremely low power consumption of 25 mW in continuous tracking mode allows great power
autonomy for all battery-operated devices, such as asset trackers, without compromising on GNSS
