Pixhawk - Marvelmind

[aravindshanmugam]

I tried to integrate Marvelmind to Pixhawk to get position fix. Unfortunately I am coming across two issues.

1. All my connections and settings are correct. But I dont get position lock (with green light on the pixhawk) everytime. Sometimes I get it, sometimes I dont. What am I missing?

2. If I get position lock and I try to loiter, my drone drifts away to one direction. Why?
