International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / Based on a fourty year experience in Telemetry, acquired on the European Space Program, IN-SNEC company (Zodiac group) has designed a versatile, modular and customable telemetry system for Airbus A380 aircraft program. This Aircraft Telemetry System (TMA-2000) comes with a large set of acquisition boards allowing numerous digital and analog inputs. The major innovation of this system lies in its modularity which allows the user to configure his acquisition chain in function of his monitoring needs and the use of an Ethernet link for its configuration as well as for telemetry output data flow.
