AUTOMATED DATA MANAGEMENT IN A HIGH-VOLUME TELEMETRY DATA PROCESSING ENVIRONMENTGriffin, Alan R., Wooten, R. Stephen 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / The vast amount of data telemetered from space probe experiments requires careful
management and tracking from initial receipt through acquisition, archiving, and
distribution. This paper presents the automated system used at the Phillips Laboratory,
Geophysics Directorate, for tracking telemetry data from its receipt at the facility to its
distribution on various media to the research community. Features of the system include
computerized databases, automated generation of media labels, automated generation of
reports, and automated archiving.

A Flexible Telemetry Processor for Spacecraft TestingLeng, Christopher, Peet, Arthur 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / In the past, telemetry data systems in support of JPL flight projects -- such as Voyager and Galileo -- were designed specifically for each mission. Third-generation computers and minicomputers were combined into a distributed system, and many man-hours of software development were invested to meet each project's unique processing requirements. These systems were used to support the Spacecraft testing on the ground and -- later -- for mission operations after launch. The Magellan System Test Data Processing Subsystem (STDPS) marks a departure from these past designs. For the first time, a re-usable telemetry-processing subsystem has been designed that is flexible enough to meet the spacecraft-testing requirements of the present project -- and can be easily changed for future projects as well. These changes are all accomplished through a user-friendly, menu-oriented interface. Extensive software re-programming is no longer required. The Magellan spacecraft is being constructed for JPL by Martin Marietta Astronautics Group, Denver, Colorado. The STDPS is currently in Denver, supporting the spacecraft testing.

Optimizing Bandwidth Utilization in Packet Based Telemetry SystemsKalibjian, Jeffrey R. 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / A consistent theme in spacecraft telemetry system design is the desire to obtain
maximum bandwidth utilization given a fixed transmission capability (usually due to
cost/weight criteria). Extensions to basic packetization telemetry architectures are
discussed which can facilitate a reduction in the amount of actual data telemetered,
without loss of data quality. Central to the extensions are the establishment of an
"intelligent" telemetry process, which can evaluate pending data to be telemetered,
and act to compress, discard, or re-formulate data before actual transmission to ground
stations.

Integrated CCSDS, SGLS and STDN Telemetry, Tracking and Command Processing SystemNichols, Alex, Goodstein, F. Robert, VanCouvering, Ken 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / This paper describes the use of an open architecture, low-cost, turnkey Telemetry, Tracking and Command (TT&C) processor system. The workstation based system was developed to satisfy the requirement for ground station equipment to handle and process multiple vehicle platforms for telemetry, command and tracking (tone or PRN), including STDN, SGLS and CCSDS link formats. The open architecture of the system allows for easy interface with external equipment for control of antenna systems, encryption units and other related station equipment. Reconfiguration for the various data formats and for system verification is done through a graphical user interfaces using operationally proven commercial-off-the-shelf (COTS) software and hardware. The open architecture of the system will allow for modifications and upgrades to be cost effective.

Mission-Independent Telemetry Processing Software for PCsMiller, Richard J. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Until the early 80's, telemetry processing systems were commonly run on mainframe or mini computers running proprietary operating systems and software with limited portability. The advent of the 'low-cost' workstation reduced the hardware cost but the software still remained relatively expensive and relatively mission specific. The workstation itself, although comparatively cheap, was not, and is still not, an everyday piece of computing hardware Telemetry Processing software has been developed by Micro SciTech to meet both low-cost hardware requirements and mission independence. It runs on networked IBM PC compatible computers and can be re-configured and used for many different missions and experiments without the need for extensive software rewrites.

APPLICATION OF ADAPTIVE COMPUTING IN SATELLITE TELEMETRY PROCESSINGFigueiredo, Marco, Graessle, Terry 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / The advent of adaptive computers built from re-programmable logic devices presents a potential solution for meeting the data processing requirements of the new era of Earth monitoring satellites to be launched by the National Aeronautics and Space Administration (NASA) Earth Science Enterprise project. The Earth Observing System (EOS) AM-1 spacecraft, the first satellite of this new era, will produce in only six months as much data as NASA has collected to this date. As a consequence, the Earth Science Data and Information System (ESDIS) project is building high performance and highly costly parallel processing systems to address the real-time data production requirements. Together with the high performance front-end ingest and level 0 processing microcircuits developed in-house at the Goddard Space Flight Center’s (GSFC) Data Systems Technology Division (DSTD), adaptive computers present a possible alternative to traditional CPU-based systems to increase the performance while reducing the cost of satellite telemetry processing systems. The Adaptive Scientific Data Processing (ASDP) project has been investigating the use of adaptive computers in the implementation of space borne scientific data processing systems. An order of magnitude processing speed acceleration over high-end workstations has been demonstrated for both level 1 and level 3 algorithms. This paper discusses the use of adaptive computing in satellite telemetry processing systems, level 1 and beyond. Primarily, it describes the efforts and presents the results of two prototypes developed by the ASDP project. The limitations of the current state of the technology are discussed and the expected improvements to facilitate the adoption of adaptive computers are presented. Finally, future work of the ASDP project is discussed.

REMOTE TELEMETRY CONCEPTSSTIERS, R., LYDON, T. 11 1900 (has links)
International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A Remote Telemetry Station (RTS) was developed to support Boeing’s requirement to relocate its flight test telemetry range away from Seattle, Wa. As requirements to relocate the test range were investigated high level requirements were documented and various approaches were evaluated. The end result of the analysis and requirements definition was the procurement of the Remote Telemetry Station (RTS). The RTS is capable of supporting many sites, tracking and receiving up to 1024 Kbits/sec of telemetry data, providing fully redundant two-way radio communication in the UHF and VHF bands, linking all the data back to Seattle and appearing transparent to the users. The RTS was designed and developed by a Boeing/Veda Incorporated team. The end result of this joint design and development effort is a system that meets all Boeing requirements in a highly integrated, extremely efficient, and very flexible package providing for growth through the year 2000.

SPACE-BASED VISIBLE (SBV) SURVEILLANCE DATA VERIFICATION AND TELEMETRY PROCESSINGStokes, Grant H., Viggh, Herbert E.M., Pollock, J. Kent 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / This paper discusses the telemetry processing and data verification performed by the SBV
Processing, Operations and Control Center (SPOCC) located at MIT Lincoln Laboratory
(MIT LL). The SPOCC is unique among the Midcourse Space Experiment (MSX) Data
Processing Centers because it supports operational demonstrations of the SBV sensor for
Space-Based Space Surveillance applications. The surveillance experiment objectives
focus on tracking of resident space objects (RSOs), including acquisition of newly
launched satellites. Since Space Surveillance operations have fundamentally short
timelines, the SPOCC must be deeply involved in the mission planning for the series of
observations and must receive and process the resulting data quickly. In order to achieve
these objectives, the MSX Concept of Operations (CONOPS) has been developed to
include the SPOCC in the operations planning process. The SPOCC is responsible for
generating all MSX spacecraft command information required to execute space
surveillance events using the MSX. This operating agreement and a highly automated
planning system at the SPOCC allow the planning timeline objectives to be met. In
addition, the Space Surveillance experiment scenarios call for active use of the 1 Mbps
real-time link to transmit processed targets tracks from the SBV to the SPOCC for
processing and for short time-line response of the SPOCC to process the track of the new
object and produce new commands for the MSX spacecraft, or other space surveillance
sensors, to re-acquire the object. To accomplish this, surveillance data processed and
stored onboard the SBV is transmitted to the APL Mission Processing Center via 1 Mbps
contacts with the dedicated Applied Physics Laboratory (APL) station, or via one of the
AFSCN RTS locations, which forwards the telemetry in real-time to APL. The Mission
Processing facility at APL automatically processes the MSX telemetry to extract the SBV
allocation and forwards the data via file transfer over a dedicated fractional T1 link to the
SPOCC. The data arriving at the SPOCC is automatically identified and processed to yield
calibrated metric observations of RSOs. These results are then fed forward into the
mission planning process for follow-up observations. In addition to the experiment support discussed above, the SPOCC monitors and stores
SBV housekeeping data, monitors payload health and status, and supports diagnosis and
correction. There are also software tools which support the assessment of the results of
surveillance experiments and to produce a number of products used by the SBV instrument
team to assess the overall performance characteristics of the SBV instrument.
