Chelton is the world's leading supplier of Avionic-standard TETRA systems, with 20 years experience in fielding TETRA in aircraft. Chelton equipment is specifically designed for airborne use, with menu structures and keyboard/display layouts suited to airborne operations. These operations are usually conducted by users wearing gloves and in the noisy, high vibration helicopter environment. Our airborne TETRA products provide configuration options to meet users' needs, including single or dual-transceivers which can be controlled by either single or dual Control and Display Units (CDUs). All transceivers are NVG compatible and can operate in TETRA's Gateway and Repeater modes.
