RT TELEMETRY NETWORK UPGRADE BASED ON ETHERNET

Abstract

New techniques for using Ethernet in real time systems are applicable to the typical requirements of high performance Telemetry installations. Most TM installations around the world today are currently implemented using specialized, high speed, point-to-point data paths which have reached their limits in performance. By using Ethernet in real time as a “Data Highway” path, system performance is optimized, and the effective life of a Telemetry system can be significantly extended. Additionally, by integrating a Local Area Network into the system, further advantages are realized. New graphics display hardware and software may be used to provide virtually an “offthe-shelf”, and very cost-effective major system upgrade. Meanwhile, little modification to the host processor hardware or software system is required. This paper examines these premises, and discusses several examples of major Telemetry systems which have made this upgrade.
