Andrew Tridgell a4d25f5a82 AHRS: removed AHRS_BARO_USE option 
this option has caused users too much trouble. The vertical velocity
is too noisy from the baro
 2013-04-15 10:52:31 +10:00
Andrew Tridgell 87b0fb05ce AHRS: changed default RP and YAW gain to 0.3

the impact of GPS lag

Note that this doesn't affect copters, as they override to 0.1

Andrew Tridgell dca597cda1 L1_Control: added a comment on speed of the L1 control code 2013-04-12 12:58:20 +10:00
Brandon Jones a3c2851120 AP_L1_Control: Addition of library for geometry calculations required for L1 Control. 
1) Explicit control of tracking loop period and damping which removes previous
   variation in period with speed and fixed damping ratio
2) Explicit control of track capture angle (now set to 45 degrees by default)
3) Removal of restriction on loiter radius being greater than L1 distance

The circle(loiter) control is a L1 and PD hybrid utilising L1 for waypoint capture and PD control for circle tracking.
