Erratic Horizon with speed sensor

Dear Gents,

Using APM board 2.5 with software 2.65

Sensors: GPS Lea6 V1.1, Volt/amp Attopilot 90A, Speed DIY drones V20

Radio 3DR 433 Mhz

 

Problem:

When enabeling the speed sensor, the art. horizon starts to get unstable and the delay from action to depict on the screen may get up to 1 second.

When additionally airspeed for calculation is enabeled the art. horizon becomes useless, because change in speed directly changes the attitude by about 20 degrees (up/down).

 

Could anyone plese tell me how to solve this problem?

 

many thanks in advance

b.r.

  • Gentleman,

    just realised, that the GPS caused the Problem on achiving a 3D fix with a high Hdop. So the fix was loitering around and found that in adv. settings  "AHRS_GPS_USE" was set to 1. By changing the value to 0 the jittering of the attitude in the art. horizon disappeared completely!

    Problem solved!
