Data Handling

Data files from all sensors are stored either in open standard formats or in the manufacturers original format for maximum interoperability with third party data-analysis software such as SeeTrack from Seebyte, Triton Elics, GIS systems, Command and Control Systems, and to facilitate data interchange with other platforms. All data is time stamped, synchronized and geo-referenced.

Through the Gavia Control Center it is possible to utilize the mission playback feature to replay the mission as a further part of post mission analysis. Typically sonar and bathymetry data is analyzed in either the provided manufacturers post-mission analysis tools or exported to a third party post-mission analysis software suite.

Data accumulated during a mission is stored in solid-state flash memory or hard drives located in the control module or in sensor modules. The memory size is selected to match the data accumulation rates of each sensor in a typical operation. Browsing and secure file transfer is available over fast wireless Local Area Network (LAN) connection. With physical access to the vehicle, such as in conjunction with a battery switch out, data can be downloaded from the vehicle via a high speed 100 Mbps LAN cable for minimal data transfer time. Data transfer is also possible without recovery of the vehicle when in range of the WLAN.

The ruggedized PC used to control the Gavia is equipped with a CD-RW drive to allow archiving of missions on removable media once transferred from the vehicle.
