Gms-b6 - GPS+Beidou Module

GlobalTop's GPS+ Beidou-2 (also known as COMPASS) dual system receiver module -Gms-g6 is a compact in size with built-in patch antenna.

GlobalTop's GPS+ Beidou-2 (also known as COMPASS) 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.

While retaining signal reception quality Gms-b6 receiver module is capable of keeping low power consumption in the order of 23mA at tracking and 29mA at acquisition.
