APM 2.5 + air speed

Posted by Aerobot on September 27, 2013 at 3:11pm

I have a APM 2.5 + . I can compile and run a file called airspeed.pde which measure airspeed. Just wondering, APM 2.5 + don't have an inbuilt pitot probe or any airspeed sensor like this

https://code.google.com/p/ardupilot-mega/wiki/Airspeed . How is it possible that it is still measuring airspeed ?

How accurate is that ? Is it good enough for a descent quadrotor ? Another question, if i have more than octa(eight) rotors, the ardupilot is not enough to send the signals. Do you know what i can use ?

If an airspeed sensor is not installed, it will estimate based on ground speed.
