U-Blox NEO-7N GPS with compass module Q's

Hey all,

I have a U-Blox NEO-7N GPS with compass module

A couple of Q’s if I may.

It wasn’t getting a fix in Mission Planner & I only had a steady green light.

I left it by a window connected to my Pixhawk and forgot about it. I thought it was toast.

A couple of hours later I have a working GPS. It now sports an additional blinking blue LED
and Mission Planner reports 3D Fix.

My question is why did it take so long to aquire gps fix ? I have other gps units in various
other gadgets that all get satellites within a minute or two (and that’s inside the house).

Also, as it has a compass built in, does it matter what direction it faces ? ie: the arrow symbol must point the same way as Pixhawk ?

Any help here appreciated.

Cheers

Paul

None of my GPS units will work inside the house. They only work with a clear view of the sky.

The compass must point in the same direction as the Pixhawk otherwise you need to set a parameter telling the Pixhawk what your compass orientation is so it knows, otherwise your copter will fly off in the wrong direction.
