deployment Changed fin deadband to .035 by using x_fin_deadband - ~1 to 2 deg

The other controls to change fin deadband still don't seem to be working or it requires a reset/use +- to enact (f_fin_db_frac_dz, etc).

deployment Performing some steering optimizations on 191:
unit_191-2015-043-1-0 (0196.0000)
P = 1.5
I = 0
D = +4
heading deadband off -1
(mean fin is -2 degrees)
2015-02-13 16:33 GMT
deployment Talked to TWR, they said they use .1 in deadband on pitch battery in Ashumet. Trying .15 db, at surface it looked to work OK.
2015-02-12 20:32 GMT
deployment -160 / 200 cc dive/climb. Trying to adjust climb cc to find a battery sweet spot. Pitch toggling on climbs.
2015-02-04 20:31 GMT
deployment Side effect of pitch adjustment is the glider is happy with a pitch angle of upper 20's for the dives.

Setting dive to cc to 160 cc (~ -40 cc) to keep the speed closer to climb speed.
2015-02-03 02:53 GMT
deployment Settings have calmed down the pitch adjustments.
2015-01-30 15:20 GMT
deployment Beginning to attempt to calm down pitch control: set up sbd for more pitch data.

Easiest item is trying setting instant gain on pitch from -3 to -1.5. This change starts after this segment:
unit_191-2015-004-4-717 (0194.0717)

Later, if time, will dig deeper into pitch gains.

Also will increase deadband to 4 degrees.

2015-01-26 18:22 GMT
deployment Changed waypoint list, slight closer inshore NE waypoint due to icerbergs.

Also eliminated cross-cal UD waypoint on the outbound transect. It will only hit the UD waypoint on the way in. This is to eliminate short dives from waypoint surfacings.
2015-01-24 04:54 GMT
deployment Changed TBD to send back first yo of data. Should have done that from the start but the glider got our default 100 m every other yo.
2015-01-08 15:01 GMT
deployment Glider is a bit unstable flying. The pitch performance seems OK but likely will investigate on an open water segment to see if gets a steady pitch.

NOTE: for next deployment move weight from top of glider to bottom (if possible in sci bay)
2015-01-07 15:34 GMT
deployment False hits at 30, 60, 100m
Not risking u_min_water_depth until the problem worsens

New yo setup for next surfacing
d_target_depth set to 190m
num_half_cycles_to_do set to 4
2015-01-06 22:15 GMT
deployment Increased dive depth to 150m
!put u_max_water_depth_lifetime 0
2015-01-06 00:45 GMT
deployment Limiting for 100 m till 100% certain of depth rating of AQD.
