Gps Ublox neo M8N:
his is the new Ublox Neo-M8N GPS module that includes a QMC5883L digital compass. This module has a high level of sensitivity and features active circuitry for the ceramic patch antenna. It also comes enclosed in plastic case to protect the module from the elements. This modules outputs precise position updates at 10Hz and also has a rechargeable backup battery for warm starts. The Ublox NEO-M8N is configured to run at a baud rate of 38400 and ships for use with Pixhawk and APM (you might need to modify the cable to fit your autopilot board).
The most important improvement with this module is the vast sensitivity it offers. This modules receives concurrent reception from GPS/QZSS, GLONASS and BeiDou meaning that you should get an excellent signal no matter where you are in the world. Not only does it have this excellent reception capabilities, it maintains its low power consumption.
