EMBEDDED MIL-STD 1553 DATA FROM A SYSTEM PERSPECTIVE

Abstract

The recently delivered Telemetry Data Handling System (TDHS) was designed to support the current and future needs of a multi-purpose realtime range system at White Sands Missile Range. The system provides for data acquisition, processing, and archival of PCM, PAM, and FM data. The addition of support for MIL-STD 1553 data input as presented in the SRAM II data format is currently in process by Loral Data Systems. The SRAM II format includes MIL-STD 1553 messages embedded in a traditional PCM mutiplex. These embedded 1553 messages must be extracted and processed in addition to standard processing of the PCM data. This paper discusses a general purpose solution to the handling of embedded 1553 data including: " Configuring the system components " Extracting the embedded messages " Processing the MIL-STD 1553 data " Testing the system
