Quad low level GPS hold still drift

Posted by Henry Gan on March 24, 2011 at 8:32am

I am using the latest Ardupirates code with Mtk 16 mediatek gps & sonar

 

 I discovered that i fly my quadrotor when i engage altitude hold, the quadrotor will remain at knee level. But the quadrotor will drift.

 

To prevent the drift, i immediate engage the GPS hold. But the quadrotor will drift and stop or stop for the position for 3-4 sec only then drift again.

 

What will be problem? 

 

Why the quadrotor will not lock at the same spot instead move around the spot?

 

Was it common for a little drift at low level flying even with GPS hold?
