Hi,

I have came across the link

a bit confusing why three GPS antennae. Is it possible to connect multiple GPS cutoffs to flight controller?

They are most probably using different satellite systems (GPS, GLONASS, BeiDou and perhaps even Galileo...) for higher accuracy and redundancy. Wish GPS didn't reserve high accuracy for military applications.

As to whether it is possible, well, it certainly is. You'd need a custom 'diversity' system to forward the most accurate location data to the FC (based on the number of 'visible' satellites) or to merge all the data from the different systems for better triangulation.

What I don't understand is why someone would spend on 3 positioning systems and not put them on a decent frame.

Nicely explained  Swapnil sir
