TLDR: PX1122R is good for us due to the following reasons:
Supports L1, L2 (we not going with L5 as only 17 satellites support it yet).
Cost effective
High accuracy
It is not as popular as F9P; but has seen success in the droning community.
Waiting for confirmation from Anthony Luo that we only need position data from the GPS and not heading data too.
