AN ADVANCED TELEMETRY SIMULATOR

Abstract

Recent developments in telemetry have resulted in an increased variety of data sources. As a result, data streams are incorporating such complexities as embedded asynchronous data streams, packets, and multiple formats. These data streams must be acquired and processed in real-time by telemetry ground stations. Most modern telemetry systems use a distributed architecture to accomplish these complex decommutation and preprocessing tasks. It is usually desirable to verify the data base setup and functional operation of the system before critical tests, as well as during test development. Most of the telemetry simulator products available today can do only a very limited simulation of the incoming data stream. This often fails to exercise many key components of the system. A new product will be described which can simulate a data stream with multiple formats, embedded asynchronous data streams, unlimited special words, and other useful functions. This product will enable the user to perform a more complete test of all of the components of the telemetry system.
