Pavel Kirienko replied to Doug Walmsley's discussion GPS Issues - Do I need a GPS Ground Plane & EMI Ring?
"Support for UAVCAN sensors in APM is a bit lacking, so the steps described in the tutorial are needed to work-around this manually. Hopefully APM will improve in this regard in the future. For purposes of comparison, Zubax GNSS 2 can be used with…"

Pavel."
