“…Although the results of the Government studies are not public and thus did not contribute to this report, it is likely that many of the recommendations of these studies do agree with many of the points made here, and with those of the NAVSPACECOM studies [12,13]. At this point, it seems advisable to consider these steps:…”

Approved for public release; distribution is unlimited. LEXINGTON MASSACHUSETTS LEXINGTON MASSACHUSETTS PREFACEThe eighteenth Annual Space Control Conference was held on 11, 12 and 13 April 2000. ESC acts as administrative sponsor of the event which is held at the Lincoln Laboratory facility on Hanscom AFB, and the program is coordinated with Air Force Space Command and the Air Force Research Laboratory. The purpose of this series of conferences is to provide a forum for the presentation and discussion of space control issues.This Proceedings documents those presentations from this conference that were received in time for pre-conference publication. The papers contained were reproduced directly from copies supplied by their authors (with minor mechanical changes where necessary). It is hoped that this publication will enhance the utility of the conference. The Space Surveillance Network Analysis Model (SSNAM) is a SSN simulation tool under development for AFSPC/DOY that will be used as a force structure decision aid, providing details of the effects of adding and deleting sensors, altering tracking requirements, and modifying event processing, among other applications. One of the tasks to which it is expected to be put frequently is to assess the performance of both an unmodified and an altered SSN at some point in the future, and to this end a durable space catalogue growth model needs to be available to the tool in order to create representative space catalogues for these future points. SenCom and the SWC were tasked by DOY to develop such a model for use by SSNAM. Dr. Susan E. Andrews Editor inIn years past, catalogue growth projections were usually executed by applying curve-fitting techniques (almost always linear regression) to historical population data for the catalogue considered in aggregate or at only the highest levels of division (e.g., near-Earth vs. deep-space). This approach had the advantages of simplicity of execution and reliability in terms of meeting the general quality-of-fit criteria applied to linear regression, but it also introduced disadvantages. Mixing orbit regimes that are volatile from a catalogue growth perspective with those that are well behaved placed an upper limit on the model's fidelity. Even more disappointing was the approach's inability to predict the future proportionality among different orbit types. While it might furnish a total NE object count for a future time, it could not predict, for example, what proportion of these NE objects would occupy a high-drag orbit regime. As the SSNAM tool will simulate observations and differential corrections, it is essential that the model be told which satellites in a constructed future catalogue occupy which orbit types, especially difficult-to-maintain ones, so that processing workload and element set accuracies may be modeled correctly.In a re-contextualization of the "short-arc" assumption, some previous catalogue growth studies have presumed that because the growth projections are usually for only a short period into the futu...

“…Composed of two dosimeters, two particle telescopes and a Single Event Effect detector, CEASE has the capability to monitor a broad range of space hazards from surface damage and charging (keV electrons) to Single Event Effects resulting from >100 MeV cosmic rays and solar protons [5,6]. The angular field-of-view for CEASE is relatively large and will not allow for pitch angle resolved measurements.…”

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to Department of Defense, Washington Headquarters Services, Directorate for Information (DoD) capability to operate spacecraft in the harsh radiation environment of medium-earth orbits (MEO). The ability to operate effectively in the MEO environment significantly increases the DoD's capability to field space systems that provide persistent global targeting-grade space surveillance, high-speed satellite-based communication, lower-cost GPS navigation, and protection from space weather on a responsive satellite platform. The three DSX physics-based research areas are: 1. Wave Particle Interaction Experiment (WPIx): Researching the physics of very-low-frequency (VLF) transmissions in the magnetosphere and characterizing the feasibility of natural and man-made VLF waves to reduce space radiation; 2. Space Weather Experiment (SWx): Characterizing and modeling the space radiation environment in MEO, an orbital regime attractive for future DoD and commercial missions; 3. Space Environmental Effects (SFx): Researching and characterizing the space weather effects on spacecraft electronics and materials. DSX uses a modular design that allows for launch either as a primary satellite on a conventional launcher, such as a Minotaur, or as a secondary payload on a larger rocket, such as the Evolved Expendable Launch Vehicle (EELV). Another key feature is the use of a dedicated payload computer, which unburdens the avionics of the need to conform to custom payload data interfaces, enabling the rapid procurement of a standard spacecraft bus. An overview of the DSX science experiments, payload design, spacecraft subsystems, and engineering approach will be described.

“…The instrument was turned on 24 hours after launch and has been operating nominally ever since. CEASE is a highly miniaturized suite of sensors and particle detectors designed foremost to provide real-time alerts to operators of hazardous radiation conditions on board satellites (Dichter et al 1998). When operated in the higher telemetry science mode, data from CEASE provides operators and engineers a clear picture of the space radiation 10 deg off RAM Into RAM 10 deg off RAM Into RAM 456 environment tremendously useful when resolving satellite anomalies.…”

Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington, VA 22202-4302, and to the Office of Management and Budget, -to review recent spacecraft measurements that have provided new insight into the dynamics and effects of space storms; -to review space weather hazards associated with space storms and pertinent to the operation of technological systems in space and on ground;-to discuss and assess methods of space weather forecasting, as well as national and international initiatives towards an efficient development of space climatology.Space weather, the invisible but nevertheless effective result of solar activity and solar-terrestrial coupling, has affected the operations of communication systems since the appearance of telegraph in the 19th century, though as an unknown trouble factor. Nowadays, the effects of space weather affect in various ways all communication modes, from cable to wireless to space-based systems. Moreover, space weather hazards include malfunction or even permanent damage of power distribution grids and of telecommunication, navigation and surveillance satellites, disturbances of over-the-horizon (OTH) radar, HF, VHF and UHF communications, surveying and navigation systems that use Global Positioning System (GPS) satellites, surveillance (optical and radar), and satellite tracking. Space weather influences on the Earth's weather and climate is still a developing topic. Little is known concerning the biological effects of space weather, especially regarding astronauts.This Institute could not be timelier. Space Weather, which has been defined as "conditions on the sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-and ground-based technological systems and can endanger human life", encompasses a broad range of phenomena impacting both space science and technology. The effects of Space Weather, while present throughout the solar cycle, gain particular prominence around the peak of the 11-year sunspot activity; the maximum of cycle 23 occurred in summer 2000.The fact that this ASI on Space Weather was held in Europe is particularly appropriate. European countries host a considerable repository of knowledge and world-class facilities in this field. Nevertheless, while Space Weather activities in c...
