THE PHILLIPS LABORATORY’S MOBILE GROUND TRACKING STATION (MGTS)Stone, Christopher E., Flint, Keith D., Mathis, Gregory P. 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / Phillips Laboratory's Space Experiments Directorate (PL/SX) is operating
and upgrading the laboratory's premier transportable satellite tracking
station, the Mobile Ground Tracking Station (MGTS) program. MGTS
supports orbital, suborbital, and aircraft missions as a range system capable
of processing and recording multiple data streams. MGTS receives,
processes, displays, and records satellite state-of-health data, infrared images
in a variety of wavelengths, video data, and state vector solutions based on
IR returns from the Miniature Sensor Technology Integration (MSTI)
satellite program.
The program has began in 1990 under BMDO sponsorship, with the intent to
supplement existing test ranges with more flexibility in range operations.
Wyle Laboratories and Systems Engineering and Management Company
(SEMCO) provided the technical expertise necessary to create the first
MGTS system. Autonomy and off-road capability were critical design
factors, since some of the operations envisioned require deployment to
remote or hostile field locations. Since inception, MGTS has supported the
Lightweight Exo-Atmospheric Projectile (LEAP) sub-orbital missions, the
MSTI satellite program, and Air Force wargame demonstrations. In pursuit
of these missions, MGTS has deployed to White Sands Missile Range
(WSMR), NM; Air Force Flight Test Center (AFFTC), Edwards AFB, CA;
Vandenberg AFB, CA; Falcon AFB, CO; and NASA's Wallops Island Flight
Facility, VA, to receive critical mission telemetry data conforming to both
IRIG and SGLS standards. This paper will describe the evolution of the
MGTS program, current hardware configurations and past and future
mission scenarios for the MGTS team.

AFFORDABLE GROUND STATION EQUIPMENT FOR COMMERCIAL AND SCIENTIFIC REMOTE SENSING APPLICATIONSChesney, James R., Bakos, Roger 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The remote sensing industry is experiencing an unprecedented rush of activity to
deploy commercial and scientific satellites. NASA and its international partners are
leading the scientific charge with The Earth Observation System (EOS) and the
International Space Station Alpha (ISSA). Additionally, there are at least ten countries
promoting scientific/commercial remote sensing satellite programs. Within the United
States, commercial initiatives are being under taken by a number of companies
including Computer Technology Associates, Inc., EarthWatch, Inc., Space Imaging,
Inc., Orbital Imaging Corporation and TRW, Inc. This activity is due to factors
including: technological advances which have lead to significant reductions in the
costs to build and deploy satellites; an awareness of the importance of understanding
human impact on the ecosystem; and a desire to collect and sell data some believe will
be worth $1.5 billion (USD) per year within five years.
The success and usefulness of these initiatives, both scientific and commercial,
depends largely on the ease and cost of providing remotely sensed data to value added
resellers and end-users. A number of these spacecraft will provide an interface directly
to users. To provide these data to the largest possible user base, ground station
equipment must be affordable and the data must be distributed in a timely manner
(meaning seconds or minutes, not days) over commercial network and
communications equipment.
TSI TelSys, Inc. is developing ground station equipment that will perform both
traditional telemetry processing and the bridging and routing functions required to
seamlessly interface commercial local- and wide-area networks and satellite
communication networks. These products are based on Very Large Scale Integration
(VLSI) components and pipelined, multi-processing architectures. This paper
describes TelSys’ product family and its envisioned use within a ground station.

A DESKTOP SATELLITE DATA PROCESSING SYSTEMBrown, Barbie, Ghuman, Parminder, Medina, Johnny, Wilke, Randy 10 1900 (has links)
International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The international space community, including National Aeronautics and Space
Administration (NASA), European Space Agency (ESA), Japanese National Space
Agency (NASDA) and others, are committed to using the Consultative Committee for
Space Data Systems (CCSDS) recommendations for low earth orbiting satellites. With the
advent of the CCSDS standards and the availability of direct broadcast data from a number
of current and future spacecraft, a large number of users could have access to earth science
data. However, to allow for the largest possible user base, the cost of processing this data
must be as low as possible.
By utilizing Very Large Scale Integration (VLSI) Application-Specific Integrated Circuits
(ASIC), pipelined data processing, and advanced software development technology and
tools, highly integrated CCSDS data processing can be attained in a single desktop system.
This paper describes a prototype desktop system based on the Peripheral Component
Interconnect (PCI) bus that performs CCSDS standard frame synchronization, bit
transition density decoding, Cyclical Redundancy Check (CRC) error checking, Reed-Solomon decoding, data unit sorting, packet extraction, annotation and other CCSDS
service processing. Also discussed is software technology used to increase the flexibility
and usability of the desktop system. The reproduction cost for the system described is less
than 1/8th the current cost of commercially available CCSDS data processing systems.

Advances in Telemetry Capability as Demonstrated on an Affordable Precision MortarDon, Michael L. 10 1900 (has links)
ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / This paper presents three telemetry techniques demonstrated on an affordable precision mortar that allowed the guidance, navigation, and control (GNC) system to be effectively analyzed. The first is a technique for the real-time integration and extraction of GPS data into a sensor telemetry stream. The second is a method for increasing telemetry bandwidth by saving a short period of high rate data and then broadcasting it over the rest of the flight test. Lastly, I present an on-board data storage implementation using a MicroSD card.

High Performance CCSDS Processing Systems for EOS-AM Spacecraft Integration and TestBrown, Barbara, Bennett, Toby, Betancourt, Jose 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The Earth Observing System-AM (EOS-AM) spacecraft, the first in a series of spacecraft for the EOS, is scheduled for launch in June of 1998. This spacecraft will carry high resolution instruments capable of generating large volumes of earth science data at rates up to 150 Mbps. Data will be transmitted in a packet format based upon the Consultative Committee for Space Data Systems (CCSDS) Advanced Orbiting Systems (AOS) recommendations. The Data Systems Technology Division (DSTD) at NASA's Goddard Space Flight Center (GSFC) has developed a set of high performance CCSDS return-link processing systems to support testing and verification of the EOS-AM spacecraft. These CCSDS processing systems use Versa Module Eurocard bus (VMEBus) Very Large Scale Integration (VLSI)-based processing modules developed for the EOS ground segment to acquire and handle the high rate EOS data. Functions performed by these systems include frame synchronization, Reed-Solomon error correction, fill frame removal, virtual channel sorting, packet service processing, and data quality accounting. The first of the systems was delivered in October 1994 to support testing of the onboard formatting equipment. The second and third systems, delivered in April 1995, support spacecraft checkout and verification. This paper will describe the function and implementation of these systems.

Reusable Software Components for Monitoring and Control of Telemetry Processing SystemsCostenbader, Jay, Thorn, Karen 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / NASA Goddard Space Flight Center (GSFC) has developed a set of functional telemetry processing components based upon Very Large Scale Integration (VLSI) and Application Specific Integrated Circuits (ASIC). These components provide a framework for the assembly of telemetry data ground systems for space projects such as the Earth Observing System (EOS) and the Small Explorer (SMEX) mission series. Implementation of the ground systems for such projects using a common set of functional components has obvious cost benefits in both systems development and maintenance. Given the existence of these components, the next logical step is to utilize a similar approach and create a set of reusable software components for the implementation of telemetry data system monitoring and control functions. This paper describes a generalized set of software components, called the Telemetry Processing Control Environment (TPCE), which has been developed to fulfil this need. This combination of hardware and software components enables the rapid development of flexible, cost-effective telemetry processing systems capable of meeting the performance requirements facing NASA in the coming decade.

PCI BASED TELEMETRY DECOMMUTATION BOARDJerome, Chris, Johnson, Edward, Sittler, Arthur, Wainwright, Ross 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / The Space Sensing & Vehicle Control Branch of the Air Force Research Laboratory and Voss Scientific, Albuquerque, NM, are developing an advanced PC and COTS-based satellite telemetry processing, analysis and display system known as the PC-Satellite Telemetry Server (PC-STS). This program grew out of a need to develop less expensive, more capable, more flexible, and expandable solutions to the satellite telemetry analysis requirements of the Air Force. Any new system must employ industry standard, open architecture, network and database protocols allowing for easy growth and migration to new technologies, as they become available. Thus, the PC-STS will run on standard personal computers and the Windows NT operating system. The focus of this work and this paper is the Telemetry Server component, and in particular, the custom-built decommutation board. The decommution board will be capable of processing frame formatted and CCSDS packet telemetry. It will be capable of fully decommutating telemetry data, converting raw data to engineering units, and providing this data to the Telemetry Server host. Time tagged engineering units or minor frames of telemetry will be transmitted to the Telemetry Server processor via on-board memory buffers. The decom board uses the PCI bus, programmable DSPs, considerable on-board memory, and a SCSI bus for local archiving. This paper presents the general architecture of the PC-STS, and discusses specific design considerations. These include trade-offs made during the design of the board’s hardware and software, operational specifications, and graphical user interfaces to program, monitor, and control the board.

POST-FLIGHT DATA DISTRIBUTION SYSTEMLloyd, Joseph W. Jr 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Desktop Processors (IBM PC, PC-compatible, and Macintosh) have made a major
impact on how the Naval Air Warfare Center Aircraft Division (NAWCAD},
Patuxent River engineering community performs their work in aircraft weapons tests.
The personal processors are utilized by the flight-test engineers not only for report
preparation, but also for post-flight Engineering Unit (EU) data reduction and
analysis. Present day requirements direct a need for improved post-flight data
handling than those of the past. These requirements are driven by the need to analyze
all the vehicle's parameters prior to the succeeding test flight, and to generate test
reports in a more cost effective and timely manner.
This paper defines the post-flight data distribution system at NAWCAD, Patuxent
River, explains how these tasks were handled in the past, and the development of a
real-time data storage designed approach for post-flight data handling. This
engineering design is then described explaining how it sets the precedence for
NAWCAD, Patuxent River's future plans; and how it provides the flight-test engineer
with the test vehicle's EU data immediately available post-flight at his desktop
processor.
