Introduction

An integrated GNSS receiver module incorporating the MediaTek MT3333 flash chip. The receiver tracks 3 GNSS constellations concurrently (GPS+Galileo+GLONASS or GPS+Beidou). The receiver has configurable low power modes and operates from a 2.8V - 4.2V supply. A 0.5ppm TXCO helps to speed up TTFF (Time to first fix). Multi-path algorithms improve position accuracy in inner-city environments. The on-board LNA provides good performance in weak-signal environments such as wearable devices.
