International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Foundation Initiative 2010 (FI 2010) is a joint interoperability initiative of the Director, Operational Test and Evaluation. The vision of FI 2010 is to enable interoperability among ranges, facilities, and simulations in a timely and cost-efficient manner and to foster reuse of range assets and future range system developments. To achieve this vision, FI 2010 is developing and validating a common architecture with a common range object model, a core set of tools, inter-range communication capabilities, interfaces to existing range assets, interfaces to weapon systems, and recommended procedures for conducting synthetic test events and training exercises. During FY 01, the project is developing the second Test and Training ENabling Architecture (TENA) Middleware Prototype as a basis for range communication. FI 2010 will advance a simulation-based acquisition or a ‘distributed engineering plant’ methodology to streamline weapon system acquisition. Benefits from the FI 2010 products include cost effective replacement of customized data links, enhanced exchange of mission data, organic TENA-compliant capabilities at test sites to be leveraged for future test events, and instrumentation system reuse. Through FI 2010, future inter-range operations, instrumentation development, and range capability sustainment will cost less and incur less risk.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Sponsored by the Central Test and Evaluation Investment Program (CTEIP) under the Director of Test and Evaluation (DOT&E), the Foundation Initiative 2010 (FI 2010) project is chartered to enable interoperability among ranges, facilities, and simulations in a timely and cost-efficient manner and to foster reuse of range assets and future software systems. To achieve this vision, FI 2010 has developed and is validating a common architecture called the Test and Training Enabling Architecture (TENA), which provides for real-time software system interoperability using the TENA Middleware, as well as interfaces to existing range assets, C4ISR systems, and simulations. The TENA middleware is being developed using an iterative development process, with functionality being released in four “spirals.” The current software version, Release 3.0, was built upon previous releases and provides some key functionality enhancements to include multicast transport, vector data types and User Datagram Protocol (UDP) multicast communication support. This paper will provide detailed information on the current status of the FI 2010 project, the TENA Middleware Release 3.0, and how the TENA software has been utilized to support test and training events (e.g., Millennium Challenge 02).

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / We discuss how aspects of telemetry can be effectively incorporated and modeled as a component within network-centric operations and warfare paradigms. Telemetry is particularly vital in Air Force Flight Test and Evaluation. As such, this paper has a specific emphasis and provides discussion within this domain. We also present how an existing framework for networkcentric operations and warfare can be particularly beneficial to telemetry modeling, and discuss the potential insights and utility within this context.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / An integrated design, Test and Evaluation (T&E) system for GPS receiver is proposed in the paper, which can perform T&E early in R&D cycle, and combine new designs into a conceptual GPS receiver directly. The flowchart of its development mode is given. The architectures of the system, especially of the signal-computing software are described with frame diagrams. The mathematical models of three reference points are derived, with the impact of oscillator errors modeled. Future plans and further developments are also discussed.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The Test and Evaluation Community Network (TECNET) has existed as a means of electronically exchanging unclassified information between Test and Evaluation (T&E) practitioners since 1983. The test and evaluation community in the Department of Defense (DoD) is heavily reliant on telemetry products. Thus, it is no surprise that TECNET deals substantively with telemetering matters. TECNET currently provides unclassified electronic mail, bulletin board, file manipulation and information retrieval services to the Test and Evaluation (T&E) community via an unclassified host computer operated and maintained by the Naval Air Warfare Center - Aircraft Division, Patuxent River, Maryland and a classified host computer located at the Aberdeen Proving Ground, Aberdeen, Maryland. National packet switched network capabilities are provided via the MILNET component of the Defense Data Network (DDN), the Defense Research Engineering Network (DREN) and a the Federal Telephone System for 2000 (FTS -2000) data network. The second TECNET computer provides a system high secret secure capability for TECNET via STU -III dial-up and the Defense Secure Network (DSNET) component of DDN. TECNET is a Joint Service network operating under the auspices of a tri-service Steering Committee which reports to a Board of Operating Directors (BoOD). TECNET supports a number of capabilities for the Range Commander's Council (RCC) community, including all scheduling for the RADCAL satellite. Presently TECNET supports a growing population of over 7,000 validated users from service Program Management Offices (PMO) and both the operational and developmental T&E communities in all the services. In the future TECNET envisions support to test planning, execution and reporting through the use of protected Multi -Level Secure (MLS) communication channels. This capability will dispense meaningfully detailed T&E related data bases and tools. The ability to provide needed, accurate, protected, high integrity, value added information at the right time and place and in the right format with the right amount of detail to the right decision makers adds direct value to the T&E process. In essence, the capability enhances the efficiency of the entire T&E process by making timely T&E information and tools more available to both its practitioners and consumers.

Differential item functioning (DIF) can occur across age, gender, ethnic, and/or linguistic groups of examinee populations. Therefore, whenever there is more than one group of examinees involved in a test, a possibility of DIF exists. It is important to detect items with DIF with accurate and powerful statistical methods. While finding a proper DIP method is essential, until now most of the available methods have been dominated by applications to large scale testing contexts. Since the early 1990s, Ramsay has developed a nonparametric item response methodology and computer software, TestGraf (Ramsay, 2000). The nonparametric item response theory (IRT) method requires fewer examinees and items than other item response theory methods and was also designed to detect DIF. However, nonparametric IRT's Type I error rate for DIF detection had not been investigated. The present study investigated the Type I error rate of the nonparametric IRT DIF detection method, when applied to moderate-to-small-scale testing context wherein there were 500 or fewer examinees in a group. In addition, the Mantel-Haenszel (MH) DIF detection method was included. A three-parameter logistic item response model was used to generate data for the two population groups. Each population corresponded to a test of 40 items. Item statistics for the first 34 non-DIF items were randomly chosen from the mathematics test of the 1999 TEVISS (Third International Mathematics and Science Study) for grade eight, whereas item statistics for the last six studied items were adopted from the DIF items used in the study of Muniz, Hambleton, and Xing (2001). These six items were the focus of this study.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Global Positioning System (GPS) was analyzed in terms of its repeatable accuracy, UTM projection for 2D plane coordinate system, satellite visibility performance and the horizontal dilution of positioning (HDOP). The principle of Dead Reckoning together with body coordinate system transformation was introduced. The complementary performance of GPS and DR, and GPS/DR integration using gyroscope and accelerometer were given. Test results were demonstrated that the repeatable accuracy of GPS alone is about 10 meters in open air, and DR can provide continuous positioning output within sufficient accuracy when GPS signal is outage.

ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Weapons System Test and Integration Laboratory (WSTIL) at the U.S. Army Yuma Proving Ground (YPG) will provide a new capability for ground based testing in this arena. Current and near term YPG scheduled test programs will benefit tremendously from this enhanced ground test capability provided by the Weapons STIL. The Weapons STIL's design goals center on the implementation of an automated mechanism for testing the weapon systems and sensors that are currently the responsibility of the YPG facility. To meet the Army's weapons test needs the Weapons STIL incorporates various levels of digital stimulation, human-in-the-loop, hardware-in-the-loop, and installed system test facility (ISTF) techniques to maximize ground testing in order to focus and optimize subsequent open air flight testing. This paper describes this work in progress.

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / The Capability Maturity Model (CMM) developed by the Software Engineering Institute is widely promoted as a method to help decrease the volume of error riddled and late software projects. Because of the projected benefits, the 96th Communications Group/SC (SC) at Eglin Air Force Base began an intensive software process improvement effort in late 1997. This effort was rewarded in September 1999 when the group achieved a CMM Level 2 software rating on its first attempt. As of December 1999, 68% of assessed organizations remained at Level 1 on their first or second assessment. The SC success was not only obtained on its first attempt, but also 11 months ahead of the industry standard. The Level 2 rating was accomplished in the volatile environment needed to support the test and evaluation mission. This environment includes frequent requirement changes, short notice modifications, and externally driven schedules. One reason this milestone was possible is close and direct involvement by management. This paper will present additional factors to implementing a successful software process improvement effort.
