Intuitive chart-based graphical mission planning is provided by the Gavia Control Centre software that runs under the Microsoft Windows operating system on a ruggedized laptop. The Gavia Control Centre supports nautical charts in standard S57 (encrypted and unencrypted), VPF vector formats that provide increased level of detail over raster charts, or GeoTiff images.
Mission plans are defined in terms of waypoints or survey lines or predefined patterns, such as lawnmower, cross-hatch, and sliding box.
Sample mission plans for a lawnmower type pattern is shown below. It is possible to use such pre defined patterns or alternately individual lines. The search area can be defined graphically on the underlying nautical chart. Once defined, the area can be moved and rotated using the mouse.
The map based Control Centre also provides text boxes for precise control over mission and sensor parameters, including sonar range, lane spacing, lane alternation ratio to ensure full coverage, vehicle speed, bottom tracking altitude, minimum and maximum depth.
