Data Filtering Unit (DFU): Dealing With Cryptovariable Keys in Data Recorded Using the IRIG 106 Chapter 10 FormatManning, Dennis; Williams, Rick; Ferrill, Paul; Eglin Air Force Base; Scientific Data Systems, LLC; Avionics Test and Analysis Corp. (International Foundation for Telemetering, 2006-10)Recent advancements in IRIG 106 Chapter 10 recording systems allow the recording of all on board 1553 bus and PCM traffic to a single media. These advancements have also brought about the issue of extracting data with different levels of classification that was written to single location. Carrying GPS “smart” weapons further complicates this issue since the recording of GPS keys adds another level of classification to the mix. The ability to separate and/or remove higher level data from a data product is now required. This paper describes the design of a hardware device that will filter specified data from IRIG 106 Chapter 10 recorder memory modules (RMMs) to prevent the storage device or computer from becoming classified at the level of the specified data.
DataProbeCLASSIC - A NEW VERSION OF THE CLASSIC DATA-ANALYSIS TOOLMcCormick, John; Ferrill, Paul; Avionics Test and Analysis Corporation (International Foundation for Telemetering, 2006-10)DataProbeCLASSIC is the new PC-based version of the classic tool for telemetry data analysis and visualization. DataProbe was the brainchild of the Unites States Navy and its contractors. At a time when computer terminals were expensive and graphical visualization of data was cutting edge, this software product was specifically designed to process time-series data in an efficient manner. The primary strength of DataProbe is the capability to read specific data items for specific time slices from very large data files rather than reading the entire data file into memory. The efficiency and versatility of the product was quickly noted, and it gained widespread use within the testing community. This paper presents a brief history of the legacy product and discusses the features and strengths of new implementation.
REFERENCE DESIGN FOR A SQUADRON LEVEL DATA ARCHIVAL SYSTEMFerrill, Paul; Avionics Test and Analysis Corporation (International Foundation for Telemetering, 2006-10)As more aircraft are fitted with solid state memory recording systems, the need for a large data archival storage system becomes increasingly important. In addition, there is a need to keep classified and unclassified data separate but available to the aircrews for training and debriefing along with some type of system for cataloging and searching for specific missions. This paper will present a novel approach along with a reference design for using commercially available hardware and software and a minimal amount of custom programming to help address these issues.
