Tugs and remote viewers (also users in the office) can then view their own survey screen, using either a web browser (no additional charge) or their own copy of Hypack. The Hypack Survey computer on the barge positions all vessels on the user-defined projection with S-57 maps, GeoTIFs and construction drawings in the background. The M3 software sends sounding data through EM. It’s optional to split the sensor data to the M3 software for M3 local recording.
The first survey line collected is associated with HYPACK file 9592200.142, however several other HYPACK files from earlier on JD 142 were recorded during equipment calibration testing. Long range antennae options allow for connections up to 2 miles between vessels. need to be connected to the Hypack software. These files represent all the navigation recorded by the HYPACK software during USGS survey 2013-003-FA south of Marthas Vineyard and north of Nantucket. Using the Hypack-supplied hardware, the GPS position from each secondary vessel is broadcast via a Wi-Fi network, making their position and heading data available to the barge computer. Tugs can then receive their own area map showing all vessels using a web browser, or have additional controls for anchor handling and targeting by having their own Hypack Survey license. Optional antennas can increase the range from 2km to over 10km. Secondary vessels (tugs) are equipped with a Wi-Fi broadcaster which takes their network GPS feed and sends the messages to the primary vessel (barge).
