Triple-Technology Land Navigation, Orientation, Control & Stabilization System (TTLN-OCSS)
Battlefield orientation and accurate navigation are among the most fundamental requirements for situational awareness – which is the key to effective command and control.
Just like naval vessels at sea and aircraft in the air, ground vehicles also depend on accurate navigation to determine their own positions, reach their destinations and conduct their operations relative to the terrain and to other elements, both friendly and hostile.
The two primary navigation technologies currently in use are GPS (Global Positioning System) navigation – a method based on input from a satellite system, and INS (Inertial Navigation System) – a method based on continuous electronic computation of motion data relative to a known initial point.
When the navigation system incorporates a suitable stabilization technology, the same inertial sensors that provide data for navigation purposes may also provide data for controlling and stabilizing dedicated systems fitted to the same vehicle, notably tank guns and surveillance systems.
ACS presents TTLN-OCSS – Triple-Technology Land Navigation, Orientation, Control & Stabilization System.
TTLN-OCSS Is a vehicle-mounted land navigation system that utilizes the two most widely-used navigation technologies: GPS and INS.
Additionally, TTLN-OCSS incorporates the Ring-Laser Gyroscope (RLG) technology that may be utilized to control and stabilize dedicated systems.
TTLN-OCSS enables vehicles to determine their own position and navigate accurately to any destination or objective. At the same time, dedicated systems fitted to the vehicle, like tank guns and surveillance systems, are kept in alignment.
