FPV Eagle Tree Systems OSD Pro GPS vs. Barometric Altimeter

[robertlbyrd]

So which port did you plug it into? I have the V4, OSD Pro, GPS, Altimeter and Airspeed sensor, and cannot find info in the manual where to plug them in when using OSD Pro?

One question.. if i get the Eagle tree OSD .. and i want to have the GPS data (speed, alt, position, bearing , distance, etc) do i have to get also the logger or the GPS extension can be plugged directly into the OSD?

And for battery data?

[MissileOnline]

which one do you believe? I've heard that GPS can be very inaccurate

I am yet to test myself.. my altimeter only arrived today :)

@MissileOnline Not sure. GPS is worse for altitude than location, and given that they both were relatively close when started out and finished, I wouldn't tend to believe there was much barometric pressure change during the flight, so probalby believe that one over the GPS...

Using generic ones from DPCAV.com...

@jeffmcclain

Your altimeter is off because your static tube is not vented properly. The static tube from the altimeter should go out the side of the plane but only flush and 90 degrees to the wind stream. Your prop thrust is pressurizing your altimeter causing the error, that is why it is close when the motor is off.

Cheers.

@thekubiaks1 Hardly. It is almost 200ft off when up high even gliding...nice guess...but wrong.

What Tx and RX are you using?
