HLY-07-02 POSMV and Navigation Data [Grebmeier/LDEO]

This dataset includes files that the POSMV Navigation computer logged onboard the U.S. Coast Guard Cutter Healy during the 2007 HLY0702 cruise. The data are from various navigation devices and from devices related to the Seabeam system. There are also event files in this dataset that are from various systems. The event files show the start and stop times and various events in the recording and setup history of the device. The individual data files are collected into tar files by day. The following is a list of the devices:
adu5 - Ashtech GPS data;
aggps - Differential GPS data;
ftsgauss - TSG data;
ftsgaussraw - Raw TSG data;
par - Raw PAR sensor data;
posatt - POSMV Attitude data;
posnav - POSMV GPS data;
posreform2sb - Reformatted POSMV data for Seabeam;
sbsv - Seabeam surface sound velocity data.
This cruise was not a Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP) project cruise, but the data are included here for historical purposes. BEST-BSIERP together are the Bering Sea project.

本数据集收录了美国海岸警卫队海利号巡逻舰在2007年HLY0702巡航期间由POSVM导航计算机记录的文件。数据来源于多种导航设备以及与Seabeam系统相关的设备。此外，数据集中还包含了来自不同系统的事件文件，这些事件文件展示了设备的记录与设置历史中的起始和结束时间及各类事件。各个独立的数据文件按照每日收集整理成tar文件。以下为设备列表：

adu5 - Ashtech GPS数据；
aggps - 差分GPS数据；
ftsgauss - TSG数据；
ftsgaussraw - 原始TSG数据；
par - 原始PAR传感器数据；
posatt - POSVM姿态数据；
posnav - POSVM GPS数据；
posreform2sb - 重新格式化的POSVM数据以适配Seabeam；
sbsv - Seabeam海面声速数据。
此次巡航并非贝林海生态系统研究-贝林海综合生态系统研究计划（BEST-BSIERP）的项目巡航，但为历史原因，相关数据亦收录其中。BEST-BSIERP合称为贝林海项目。
