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).

heading deadband off -1
(mean fin is -2 degrees)

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
dkaragon
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
dkaragon
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.

deployment Settings have calmed down the pitch adjustments.
2015-01-30 15:20 GMT
dkaragon
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.

dkaragon
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.

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
dkaragon
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)

deployment False hits at 30, 60, 100m
Not risking u_min_water_depth until the problem worsens

New yo setup for next surfacing
