Plasma and Energetic Electron Environment and Effects Extension S/C Anomaly Analysis

ESTEC/Contract No. 13561/99/NL/SB

Minutes of the Progress Meeting PM1


Held at

Swedish Institute of Space Physics, Lund

17-18 June 1999

  1. General status of the project
  2. Lars Eliasson presented the general status of the project. Work has started according to the proposed work packages.

    Alain Hilgers addressed the importance of creating a European database of satellite anomalies.

  3. Adoption of Agenda
  4. The agenda was updated and agreed.

  5. Presentation of work done
  6. Peter Wintoft presented the prototypes of the analysis module WP 205, the prediction module WP 305, first thoughts on the database WP 110 and the developed webpages.

    General comments

    It should be indicated on the web-pages that launches Java applications what kind of browser the program can be run on. For the final software, the minimum requirements are the latest versions at the end of year 2000 of Netscape and Internet Explorer running on PC Windows 95/98 and SUN Solaris.

    Version information is essential on all issued document.

    Analysis module

    An interface should be included so that the analysis module can work with user provided data. The flowchart must be updated to clarify this aspect.

    Anomaly analysis should be possible by using:

    – environment parameters alone and/or together with

    – past information from spacecraft

    Time schedule

    The time schedule was discussed. It was noted that WP110 is behind schedule. A preliminary version of the URD will be delivered beginning of July. The list of people to contact a draft questionnaire for them to provide information on their requirements will be submitted to ESTEC for approval by Tuesday 22 June. A revision was suggested and agreed to take into account the summer leave of Peter Wintoft and additional work required on WP205 and WP210.

    A preliminary version of the URD for SAAP (WP210) will be delivered at T+5. A new version of the prototype (WP205) will be made and delivered at T+6. WP210 is extended by 2 months and expected to be ready at T+7. WP220 will start at T+7 and end T+11.

    The URD for SAI (WP310) will start at T+6 and end at T+8. WP320 will start at T+8 and end T+12.

    A revised version of the time schedule will be made and further maintained on the internal pages on the server.

  7. List of people
  8. A preliminary list of organisations (people) to contact was discussed. The following were recognized:

    Esrange Jonny Järnmark

    SSC Sven Grahn

    DLR/ESOC Thomas Kuch

    CNES Jean-Yves Prado, Jean Pierre Catani


    INTELSAT Ozkül

    ONERA Manola Romero

    DERA D.J Rodgers


    A questionnaire will be sent to the organisation.

  9. Data to be included
  10. General public data

    As a minimum, the following data will be included:

    GOES 8 and GOES 10, electron and proton data

    ACE data


    Predicted Kp

    Predicted solar wind velocity

    Preliminary or predicted data will be used for prediction, i.e., SAI only but not archived in the database.

    NOAA satellites will in the future be available down to lower energies, but for this study use of LANL satellites low-energy data is foreseen. A meeting will be arranged end of July (week 30) together with G Reeves and Peter Wintoft to discuss this topic further.

    High-energy protons in the radiation belts are a concern for, e.g., low altitude satellites. Anomalies due to these particles can be identified by their distribution in geomagnetic coordinates.

    Solar particle events should be included. GOES data or neutron monitor data should be considered.

    Satellite anomaly data

    This study should put special emphasis on European data, however provision will be made to incorporate other satellite anomaly databases, especially NSSDC.

    It should not be possible to retrieve the anomaly data from the database, only to use it for correlation, statistical analysis and prediction studies.

    Names of spacecraft shall never be disclosed to users

    NSSDC should be contacted and informed about our use of the data set.

    It was decided not to keep predicted anomaly data in their database.

  11. Database format. ASCII files or, e.g., SQL, Java, object-oriented, SEDAT, SEC.
  12. Use of ASCII files is recommended.

  13. Discussion of data base tools.
  14. The database tools include user driven and server driven data base access and formatting tools.

  15. Suggestions for the URD of WP110.
  16. Inputs for the URD were given in the previous discussions.

  17. Administrative matters
  18. Contractual aspects

    Contracts are signed. Advance payment invoice has been sent to ESTEC. The advance payment has been received by the contractor.


    Include Eamonn Daly in the list to receive the monthly report.

  19. Action Items
  20. Alain Hilgers will check if information in monthly reports and minutes have to be made public at the end of the contract. If not care must be taken not to disclose strategic information on, e.g., some data sources.

    Peter Wintoft will draft a list of questions and the list of people to contact and send to Alain Hilgers by the 22 June.

    Alain Hilgers will send ESA documents describing the standard form of URD to Peter Wintoft by 21 June.

    Peter Wintoft will contact NSSDC to investigate if there are any restrictions in using NSSDC-data for this project.

    Alain Hilgers will contact G Reeves and M Hapgood to arrange a meeting during week 30.

  21. Other matters
  22. A short discussion was held on possible interaction with SEDAT. It was decided to ask M Hapgood whether a copy of SEDAT URD could be sent to Peter Wintoft to investigate possible collaboration.

  23. Next meeting

The next progress meeting was decided to be held in Kiruna 28-29 October, 1999.
