AIR PUMP KICKS IN AT SURFACING BEH START IE: RUNNING OUT OF YO'S DEPTH, CLIMB TO DEPTH

Had it at 75 m, changing to something shallower.


ru26d-2019-322-0-16-mbd(00270016) strange segments during storm were likely from no GPS. Not sure if air pump failing or just waves or too short of timers or pressure sensor drift. Increased vacuum readings in SBD file.

Realistic spin speed is < 100 deg / min

Running spin mission to test depth averaged currents. Should spin with -45 commanded fin to 1km
Test completed:
ru29-2012-179-0-0 (0041.0000)

Result is .95 km in 3.7 hrs @ 264.11 deg =
7.1 cm/s @ 264.11 deg

Glider reported at that surfacing:
m_water_vx(m/s) = -0.0698
m_water_vy(m/s) = 0.0230
==> 7.35 cm/s @ 288 deg

Glider reported previous surfacing:
m_water_vx(m/s) = -0.0678
m_water_vy(m/s) = 0.0352
==> 7.64 @ 297.4

Glider reported 1 surfacing post:
m_water_vx(m/s) = -0.05251
m_water_vy(m/s) = 0.02058
==> 5.64 cm/s @ 291

8/21 rough estimate about 1 deg / sec

Deep inflection depth held during RUDIC outage, this caused quick inflections at depth causing a massive battery drop. The battery recovered after swimming to normal envelope.

Glider recovered aboard Cape Hatteras by Dave K, Austin, Nilsen.

7/12-13 RUDICS outage caused TWR dockserver overload. Missing data & surfacings due to this, trying to recover data from TWR.

Created by: dkaragon @ 2012-07-14 10:00:10Informational

Due to the DS/RUDIC's fiasco, top inflection depth never changed from 50 meters once we got on the shelf. This has used much of the remaining battery. Shut science off last night and will fix at next surfacing.

Likely enough energy to fly through today and then drift.

Created by: dkaragon @ 2012-07-12 21:28:31Informational

Glider unable to call Rutgers RUDICS at this point in time, calling TWR with script on.

Altimeter back on next surfacing, 20 m off bottom, double yos to 50 m.

New on-shelf waypoint. Will set up tomorrow morning for long shelf crossing mission.

Fin deadband set to 3 by x_fin_deadband

inflect at 100 m test passed, 200 m currently running

Running 3 yos 50 to 985 over the weekend.

Increased no_comms to 12 hours.

Great performance with it turned off

Set fin offset back to 0, still decent but not as good.

Overnight setting fin offset back to 3 and fin deadband to 3 degrees

Heading deadband turned off overnight, 1 yo, 1km

Trying 1.5 degrees heading deadband.

Abort was for 100 cc not being enough surfacing volume. Set to 175 cc for surfac10 and 40

Trying gain = 30 on der_error

Flew last night with fin offset set to 3 degrees. Helped a bit, but still needs work.

Was going to do a spin test but glider mission is running longer than expected, about 4 hours. Will save for tomorrow.

Had to extend no comms to 8 hours. It surfaced for no comms so 7 hour no comm wasn't quite long enough.

Created by: haskins @ 2012-06-25 13:01:57Informational

Increased dive depth to 980m

Increased no comms to 7 hours.

Sent over new tbdlist which will decrease the size of the tbd's to make them manageable again.

Long connection time was due to catching the glider up and transferring all the tbd's over.

Created by: haskins @ 2012-06-24 15:13:10Informational

Increased dive depth to 700m

Increased No Comms to 6 hours

Waypoints changed to

LONGITUDE LATITUDE
-7152.1340 3855.5600
-7117.4050 3918.1120

I hardcoded this goto list please keep that in mind when changing other ma files.

Retasked. Dive to 500 m, climb to 30 m, 2 yos, 4 hour no comms. Mission ended and restarted; not resequenced.

Created by: haskins @ 2012-06-22 13:52:10Informational

At ~1:30pm surfacing I modified the yo20.ma so that our climb to depth is now 20m unless we are surfacing.

Will monitor and possibly extend fly time to three hours or so.

Created by: haskins @ 2012-06-22 13:50:33Informational

At 11am surfacing goto was updated to send the glider offshore and then North to continue avoiding shipping lanes.

Flying better

-215 cc, 170 cc

Envelope looks good, needs new SBD

Created by: dkaragon @ 2012-06-19 18:52:04Informational

2 hour missions, 8 m off bottom, changed SBD for more shallow data (ie: more yo's)

Created by: dkaragon @ 2012-06-19 16:21:25Informational

Flying in small envelope, decreased altitude and top inflection depth. If that is not causing it then glider might think it is stalled.

Using -1000/+150 cc
