GlobalTop’s GPS+Glonass dual system receiver module –Gms-g6 is a compact in size with built-in patch antenna. It utilizes MediaTek's new generation GNSS chipset "MT3333" supporting various location and navigation applications including autonomous GPS, GLONASS, Beidou, QZSS, SBAS, DGPS (RTCM) and AGPS. Up to 210 PRN channels with 99 search channels and 33 simultaneous tracking channels are supported.

This brand new GPS+Glonass module stands out at a much lower power consumption than those in the Gms-g series while retains the same level of performance (23mA at tracking and 29mA at acquisition).
