A SOFTWARE APPROACH TO MARS-II DIGITALLY RECORDED TELEMETRYHart, Dennis L. 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The MARS-II digital recorder is one of the new technologies that will eventually
replace the labor intensive and hardware dependent methods associated with
traditional analog-based telemetry ground systems. The Standardized MARS-II
Analysis and Reduction Tool (SMART) is one of the first software systems
developed to take advantage of this new digital recording capability. It
processes pulse code modulated (PCM) encoded data and MIL-STD-1553B
message traffic, outputting time-tagged PCM frames or 1553 messages to file.
The goal of this software is to provide a portable application that utilizes state-ofhe-art, general purpose hardware for rapid telemetry data processing to meet
the needs of operational users, telemetry engineers, and data analysts. To
satisfy these goals, the software was developed using the C language with VMS
and OSF operating systems as the initially targeted platforms. In addition, an X
Window System/Motif graphical user interface supporting three tiers of user
interaction (operator, telemetry engineer, and telemetry analyst) was layered
onto the decommutator functions.

Mission Integrated Decommutation and Analysis System (MIDAS): Extracting Data from Digital Tape Recordings on a PCThornberry, Lewis, Lake, Phyllis, Lawrence, Ben-z 10 1900 (has links)
International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper presents the Mission Integrated Decommutation and Analysis System (MIDAS), a multi-threaded, multi-processing application developed in Microsoft Visual C++ for Windows NT by the Air Force Development Test Center (AFDTC) Eglin AFB, Florida. The primary function of MIDAS is to support post-test processing of instrumentation data by decommutating, logging, and reporting MIL-STD-1553B or pulse code modulated (PCM) encoded data extracted from MARS-II digital tape recordings. MIDAS processes multiple data streams from a single recording, and can process multiple recordings in parallel. MIDAS also serves as a diagnostics tool for investigating data processing anomalies reported during normal production runs. MIDAS is part of an integrated suite of applications developed to provide AFDTC development test and operational test customers with quickly delivered, high-quality data products. Software development is underway to support the processing of Digital Data Acquisition and On-Board Recording Standard (DDAS) packetized telemetry data. DDAS is derived from the Consultative Committee for Space Data Systems (CCSDS) standard. [MARS-II is the digital acquisition and recording system supported by MIDAS. MARS-II was developed by DATATAPE, Incorporated, Pasadena, California. It records up to 20 gigabytes of mission data across as many as eight channels of MIL-STD-1553B or PCM encoded data. Digital recording technology provides an alternative to traditional analogbased telemetry ground systems.]

NOW IS THE RIGHT TIME FOR SOLID STATEBerard, Al, Nixon, Chris, Lockard, Michael 10 1900 (has links)
International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / For the last 30 years Magnetic Tape Systems have been the primary means of recording data from
airborne instrumentation systems. Increasing data rates and harsh environmental requirements have
often exceeded the ability of tape-based systems to keep pace with technology. Throughout this time
data recordings have been made mostly with analog longitudinal systems and most recently with
digital recording systems that record on commercial DLT, and super VHS tape media. The recordings
are played back with the same type of tape device allowing for the data to be processed and/or
archived. Since not all data reduction facilities can process the same type of tape media, often tapes
are dubbed from one type of tape media format to another, corrupting the translated data. This paper
examines operational and data reduction benefits, and life cycle cost of Solid State Recorders as a
replacement for existing airborne tape recorders.
