Switched Telemetry System (SwTS) Standard For Bidirectional Telemetry Interoperability

Abstract

A look at the standardization of bidirectional Switched Telemetry Systems (SwTS) while leveraging existing telemetry receivers and transmitters. This paper will cover how current IRIG standards would include the use of existing telemetry components to support interoperability of bidirectional links across multiple vendors. Key system design aspects in transmit power control, receiver synchronization and RF switching components to allow multiple vendor interoperability are presented. These bidirectional SwTS systems based on upgrading current systems will leverage decades of work by the government and vendors to create error free down-link telemetry links under difficult RF environments. Key design areas providing for multi-vendor compatibility of bidirectional telemetry will be identified which is based on the development and testing of a SwTS system. Standardization of system configuration, in flight status and control required to support fielded SwTS systems will also be covered.
