Abstract

<strong>Overview</strong> <br>The Human Machine Interface (HMI) Conventions Document has been developed under the direction of and with oversight from the United States (US) Air Force Space Command (AFSPC). It provides recommended HMI conventions for use in designing satellite operations systems. The intent is to provide sound HMI practices for either: satellite operations programs, which are planning upgrades, or for new programs, which employ operator workstations to perform any satellite operations activities. <br>The conventions described in this document were developed to be as flexible as possible, while attempting to ensure commonality between satellite operations systems. Every effort has been made to maximize the incorporation of basic industry standards, existing/proven program designs, and derive specific conventions where necessary to meet unique domain requirements. The conventions are based upon the latest Air Force Satellite Control Network (AFSCN) Employment Concept (Department of the Air Force, 1996) and the Functional Task Analysis (FTA) (Lockheed Martin Mission Systems, 1998). The FTA captures specific tasks, operator decisions, and screen content determined to be necessary to accomplish each task. These conventions are also consistent with Volume 1 of this document and the American Institute of Aeronautics and Astronautics (AIAA) Recommended Practice for Human-Computer Interface for Space Systems Operations (HCISSO) [BSR/AIAA R-023A-1995, 1995].
