Dual GPS question

Posted by Greg on April 29, 2015 at 3:15am

I am thinking of adding a second GPS unit to my Pixhawk powered hexacopter.

Do I need to run through the hardware configuration again, or just modify the parameters as described here?  http://copter.ardupilot.com/wiki/common-optional-hardware/common-positioning-landing-page/common-installing-3dr-ublox-gps-compass-module/#connecting_to_pixhawk

    Thanks for the advice.  I've got it working.

    It is known that when it switches between GPS units it causes twitching. It will default to the GPS with more satellites and switch when one has 2 or more.

    Once the second GPS is connected you just have to change the 2 params: GPS_AUTO_SWITCH and GPS_TYPE2.Its a good idea to have 2 GPS units. If one fails the other will take over.
