Description: | Kearfott SEANAV Fiber Optic Gyro system came to end of life on Nov 3, 2012. A rental IXSEA Hydrins III system was secured to replace it with normal operation Dec 6, 2012. The SEANAV raw GPS data was captured during much of this missing data period yielding only Date, Time, Latitude, Longitude, NorthVelocity (m/s), EastVelocity (m/s) records at 1Hz. The gps-only data are available as nav: magnavgpsM1.a1. Some SEANAV type full motion data are available during a Dec 4 thru Dec 6 testing period by special request to the mentor. |

Subject: | MAG/NAV/M1 - Missing data |
DataStreams: | magnavM1.a1 |
Description: | Data loss due to AMF2 data system computer and virtual machine problems. Note that the data gap begins when ship was docked at Long Beach. NAV data are not generally used when ship is at dock. Ship left Long Beach on June 8, 2013 at 11:25. So data gap while at sea is June 8, 2013 11:25 to 17:02 UTC. Surrogate data sources may be possible depending upon actual requirements. Contact SEANAV mentor for discussion. |

Subject: | MAG/NAV/M1 - SEANAV system end-of-life issues begin |
DataStreams: | magnavM1.a1 |
Description: | When initially purchased, it was not realized that the SEANAV Fiber Optic Gyros (FOG) have a predictable life time before degradation and failure. In October 2012, the FOG end-of-life issues started to appear. The problem was not diagnosed immediately. When the internal FOG lasers go below a selected intensity the SEANAV enters a "NO GO" mode and data ceases. When this failure cause was finally identified we learned it was possible to delay the failure by adjusting internal laser thresholds somewhat, not affecting data quality. The specified data outages are due to these NO GO periods and data resumed when laser thresholds were further lowered. Ultimate failure was however reached on Nov 1, 2012 at 16:24 UTC. GPS data from the SEANAV was still available and data records with date, time, latitude, longitude, northvelocity (m/s), eastvelocity (m/s) were collected into a new data stream named magnavgpsM1.a1. These data do not contain any ship attitude data such as roll/pitch/yaw. Note that ship attitude data is also collected from motion sensors associated with other MAGIC instruments. These alternate/surrogate motion data sources might be useful depending on the particular need. Contact the SEANAV mentor for discussion. |

Subject: | MAG/AOS/ALL/M1/S1/S2 - Ship in port |
DataStreams: | magnavM1.a1 |
Description: | The ship was in port during these periods and the measurements may be affected by various sources (overhead cranes, anthropogenic sources, etc). Note: Dates and times were found by looking at the NAV datastream. The standard deviation of pitch, roll, and surge velocity were used to determine when the ship was slowing down to enter port or speeding up to leave port. Thresholds used; pitch (0.01), roll (0.01), surge velocity (3.0) |
