Technical Session II: Advanced Operations Concepts
Abstract
STEP mission 4 needed a better system to allow engineers and mission operations people to view archived spacecraft telemetry data. TRW Spacecraft Operations East in Chantilly, Virginia responded with a PC-based system in a few weeks. Software refinements to the system continued for about two months. This paper outlines the design and implementation of that small satellite telemetry data reduction system which was designed for integration, test and on-orbit operations for the STEP Mission 4 spacecraft. The notable feature of this system is that it is composed of mostly COTS hardware and software which kept the system development cost low and resulted in a short development time frame. The system provides a method to convert raw binary telemetry data into ASCII records of engineering data which can be imported into Excel, Matlab or similar tools. The data can then be plotted by the user.
