HYPACK Automatic Download of ENC Charts This new feature allows U.S.-based users to quickly ob- tain the most recent charts provided by NOAA and the US- ACE at no additional charge. U.S.-based users who have an Internet connection will be able to download the charts from the USACE and NOAA web-map serv- ers with the click of a button. Both agencies have made their charts available for download, and HYPACK has made it easy to ensure users have the latest chart data. This is a two-step process: 1. Step One: Update ENC Catalog: HYPACK downloads the latest chart catalogs over the Internet from the NOAA and USACE map servers. This information is stored in the HYPACK 2014 folder. 2. Step Two: Add ENC Charts: HYPACK automatically downloads any NOAA S-57 Charts or USACE IENC Charts. It uses the extents of the HYPACK Map window and downloads any chart that has information inside that window. The charts are saved to the ACOE or NOAA subfolders under the \HYPACK 2014\ Background folder. In the fi gure below, HYPACK 2014 downloaded fi ve charts from the NOAA S-57 chart server and one chart from the USACE IENC (ACOE) chart server. It auto- matically sorts the chart to place the ones with the most detail on the top of the display. The Advanced menu item displays the Web ENC window which allows for more specifi c control over which charts are loaded. (By Lourdes Evans) www.hypack.com EdgeTech System for Polish Defense AUVs EdgeTech said that with the introduc- tion of the 2205 AUV-based sonar system, manufacturers and operators of smaller sized AUV systems have embraced the high quality sonars which were traditionally only avail- able in larger sized AUV systems. The recently delivered Teledyne Ga- via AUVs to the Polish Ministry of Defense for mine countermeasure’s (MCM) were equipped with the latest EdgeTech 600/1,600 kHz simultane- ous dual frequency side scan sonar payloads. The very high frequency EdgeTech systems were selected for the long range detection and the ul- trahigh resolution classifi cation capa- bility for MLO’s (mine like objects). The EdgeTech 2205 classifi cation frequency of 1,600 kHz is capable of producing near photographic quality images of targets making MLO tar- get classifi cation very easy as shown in the attached MLO sonar image. Other 2205 attributes that contributed to the selection of the EdgeTech sys- tems were low power, small electron- ics’ volume and compact transducers making integration on the small AUVs possible and easy. www.edgetech.com Image: EdgeT ec h Five NOAA S-57 Charts and One USACE IENC www.seadiscovery.com Marine Technology Reporter 59 MTR #3 (50-64).indd 59 4/9/2014 2:18:34 PM
