Recovered by Matthew Breece and Danielle Haulsee. Heavily fouled with fuzz/string.

Created by: haldeman @ 2013-06-28 01:25:41Informational

Next surfacing will retask to 1 hour missions for remainder of night; recovery early tomorrow morning.

30 deg upcasts (water is getting light)

Created by: dkaragon @ 2013-06-23 10:42:35Informational

Glider aborted for low relative charge. This is based on TWR setting for lithium life:
f_coulomb_battery_capacity(amp-hrs) 720.0

We did not define in mission so it took 10% remaining = abort.

Changed upcast to 28 degrees to combat lighter waters.

Setting capacity to 750 AH and mission to 5% for abort. Downloaded MBD, voltages @ high load look OK.

Re-tasked back towards recovery location but we can change this for our last ~week.

Switched back to upcast AP, so now both up and down are AP pitch.

initial.mi and lastgasp.mi we're correct, but added versions with overtime abort of 1 hour.

RE: Fin Abort

Multiple use +, and an exit reset did not put the fin back in service. Setting c_fin to 'stuck' m_fin did not help. Finally tried one last use + digifin and it worked. Similar symptoms seen in lab with 'stuck' digifin so could have been a single external incident. No problems since, will check oddities for fin since.

Iridium outage 5/2 EST PM

Changed to battpos dives again
.3 in D, .1 in C

We were sampling bottom a bit, so trying to see if we can calm down the pitch response.

Created by: dkaragon @ 2013-04-22 21:25:53Informational

Back to AP pitch, see if it is more aggressive on the angles to speed up the glider a bit.

Changed to battpos flying and lowered surface inflection to 4 m; .27D, .075C (in)

PID heading = 1, .015, 7.5
(still getting oscillations, dives and climbs are so short)

Created by: dkaragon @ 2013-04-16 12:08:33Informational

Lack of detections and some 0 size .vem files lead us to bring the glider deeper to get below u_reqd_depth_at_surface of 2 m. Incidentally (not sure if coincidence) we got our first tag hits.

Continuing to make sure glider is below u_reqd_depth_at_surface for VEMCO reasons:

u_reqd_depth_at_surface = 1.5 m

3 hour missions, advanced to next waypoint because of strong south currents.

Created by: dkaragon @ 2013-04-11 16:43:44Informational

1.5 hour missions.

Set u_hd_fin_ap_gain 1 from 1.25

Heading during the trouble segment last night was due to CC algorithm problem. Still not sure why the glider is calculating either currents or its speed wrong.

Created by: dkaragon @ 2013-04-11 14:15:13Informational

1 hour missions during the day.
Changed some heading gains

u_heading_deadband -1 (glider doesn't fall off course with integrated reset)
u_hd_fin_ap_dgain 5

Created by: dkaragon @ 2013-04-11 14:14:34Informational

Glider currents notroriously southward, and acting strange with its CC turned on c_heading. We are investigating.

Glider Deployed by Matt Breece

Ballasted for 1023 @ 7C

Decided we were a little light so after first shallow mission we pulled glider and add two wing rail weights. (13.125 grams each in water)

Second shallow proved success currently on 45 minute missions.
