CZECH C3I SYSTEM First design Ground Forces Tactical Command and Control System
(GFTCCS) in 1996 Presentation layer - desktop application Limitations:
Speed of interaction operator-system Display resolution 2D visualization
Defense research project (2007-2008): VR devices in modernized conception of implementation of GFTCCS in the Czech Army Forces
New presentation layer with VR devices – 3D

QUESTIONNAIRE
New presentation layer - only supporting tool of the current GFTCCS
3D solution with implemented VR devices is a key factor to increase situational awareness
The implementation of VR devices should be executed as a step-by-step process
Details must not endanger lucidity

VISUALIZATION3D Terrain visualization including topographic objects and features
- Standard Army of the Czech Republic available (shared with the GFTCCS)
- digital elevation model- digital vector map- digital satellite or aero images- digital topographic maps
- WGS-84 coordinate system- Fast terrain and objects generation time

VISUALIZATIONTopographic features and object reconstruction
• Utilize low-resolution satellite images• Adds details and emphasizes important topographic features and
objects• Combines vector and raster data• Matches the original by its dimensions and shapes• Uses pre-defined sets of textures

VISUALIZATIONMilitary tactical symbol visualization
• Represented as 3D objects
• Tactical symbols mapped on semi-transparent square block
• Tactical lines floating in 3D space
• Compatible with APP6a standard
![Page 13: Virtual Reality Environment in C3I Systems Jan Hodicky, Petr Frantis Communication and Information Systems Departement University of Defense, Brno Czech](https://reader035.vdocuments.mx/reader035/viewer/2022062517/56649f2f5503460f94c493ce/html5/thumbnails/13.jpg)
• New presentation layer of GFTCCS– 3D visualization– Immersion– Utilization of VR devices for user input– Versatility
• Issues– Quality of digital terrain data– Unit symbol placement
