  • INTEGRATING THE JOINT ADVANCED MISSILE INSTRUMENTATION (JAMI) TIME SPACE POSITION INFORMATION (TSPI) UNIT (JTU) INTO A TELEMETRY SYSTEM
    2005
    Co-Authors: Steven J. Meyer
    Abstract:

    The Joint Advance Missile Instrumentation (JAMI) program has developed a Time Space Position Information (TSPI) unit (JTU). The JTU employs a novel use of Global Positioning System (GPS) technology, and inertial measurement units (IMU) to provide a real time trajectory for high dynamic missile systems. The GPS system can function during high g maneuvers that an air-to-air missile might encounter. The IMU is decoupled from the GPS sensor. The IMU data is a Secondary Navigation source for the JTU and will provide platform attitude. The GPS data and IMU data are sent to the ground in telemetry packet called TSPI Unit Message Structure (TUMS). The TUMS packet is sent to a computer that hosts the JAMI Data Processing (JDP) software, which performs a Kalmam filter on the GPS and IMU data to provide a real time TSPI solution to the range displays. The packetized TUMS data is available in three different output formats: RS-232 serial data, 16-bit parallel and PCM. This paper focuses on how to integrate the JTU into a telemetry system, use it as a standalone system, and provides examples of possible uses.

  • TELEMETRY GROUND STATION CONFIGURATION FOR THE JOINT ADVANCED MISSILE INSTRUMENTATION (JAMI) TIME SPACE POSITION INFORMATION (TSPI) UNIT (JTU)

The TUMS packet is sent to a computer that hosts the JAMI Data Processing (JDP) software, which performs a Kalmam filter on the GPS and IMU data to provide a real-time TSPI solution to the range displays. This paper focuses on the equipment and software needed at a telemetry ground station to display the real time TPSI solution on the range displays. It includes an overview of the system data flow. This overview should help a potential user of the system understand what is involved in running the JAMI system. The post mission tools to provide an accurate trajectory and end-game scoring will not be discussed in this paper.

  • Secondary Navigation in software wizards
    Human Factors in Computing Systems, 1999
    Co-Authors: Mary C Burton, Daina Pupons Wickham, Lori Phelps, Kelly Ann Spain, Janna Crews, Nicki Rich
    Abstract:

    The authors conducted a study of three approaches to Secondary Navigation in software wizards. Secondary Navigation refers to user interface Navigation controls that are in addition to the standard "Back" and "Next" buttons in a software wizard. We tested three Secondary Navigation controls: table of contents, tabs, and drop down menu. The goal of this study was to assess the benefits of Secondary Navigation controls in terms of user success with and user preference for the controls in the context of a software wizard. Thirty participants across three IBM sites tested prototypes of wizards with Secondary Navigation controls. We found that study participants were more successful with and preferred the table of contents Secondary Navigation control, participants continued to rely on the Back and Next buttons for Navigation in the wizard, and participants preferred a Secondary Navigation control to having no Secondary Navigation control in a wizard.
