Monthly Progress Report


Period: 2000-11-01--11-30

Authors: Lars Eliasson and Peter Wintoft

1. Progress status

This month started with the SAAPS PM at ESTEC on November 2. The meeting went as planned and the agenda and minutes can be found at http://www.irfl.lu.se/saaps/saapsint/schedule/pm4.html. The reports given at that meeting and the minutes are considered as the Monthly Progress Report for October (SAAPS-MR-19-99/00).

After Alain Hilgers suggestion we contacted Andrés Galvez at ESA HQ in Paris about satellite anomaly data that they have. From communications by email, phone, and finally a meeting between Alain and Mr Galvez at ESTEC it was found that the data they have are not useful for us.

Paolo Maldari was again contacted via email (Nov 6) to explain what he meant by "official channels". No reply has been received yet. He will be contacted again in December.

A generic model to load data, pre-process, load neural network parameters, run the network, and post-process have been developed. The neural network model for the prediction of anomalies from daily sums of Kp has been implemented with the new SAAPS model code. The predictions from the model have been verified using a Matlab model. The anomaly model has not been implemented yet. The generic model also opens the question of how a model database should be implemented.

A Test Plan for SAAPS has been written. Version 0.2 from November 14 exists on the web at http://www.irfl.lu.se/saaps/saapsint/.

Updates of both the Dataplotter and Superposed Epoch Analysis tools have been made. It is mainly the graphical interface that has been improved.

The help pages have also been updated.

A new tool has been added to the prediction module. It uses the latest 5 minute GOES-8 >2 MeV electron flux to calculate a running 24 hour (daily) fluence. It then creates a plot with green, yellow, and red colours based on threshold levels found by Wrenn. For yellow and red levels the risk for internal charging is increased. The new tool can be found at http://sol.irfl.lu.se/saaps/saaps user1/.  

WP 110 URD for the database and database tools

An updated User Requirements Document for the database and database tools URD v ersion 1.1 of WP110 was delivered on 27 April 2000.

WP120 SRD for the database and database tools, DB&T

The SRD Version 1.0 was delivered on August 18 2000.

The technical note TN 1 (Database and database tools) version 0.2 was delivered on 31 January 2000. This note had previously the title Exploration of data.

WP130 Development of DB&T

The database is running including all data that appear in the URD except the low-orbit data.

Historic data set consists basically of the OMNI data. All real-time data are being stored and some data are transferred to the historic data set.

Five anomaly data sets are now included. Some smaller updates have been made. The beta version will be made available before asking for more data from operators.

WP140 Test and update of DB&T

A Test Plan for SAAPS has been written. Version 0.2 from November 14 exists on the web at http://www.irfl.lu.se/saaps/saapsint/.

WP205 Prototype of Satellite Anomaly Analysis Module, SAAM

A description can be found at: http://www.irfl. lu.se/saaps/saapsint/wp205/wp205doc.html

WP210 URD for SAAM

The User Requirements Document for the Satellite Anomaly Analysis Module URD W P210 version 1.1 was delivered on 4 November 1999.

WP220 SRD for SAAM

The SRD Version 1.0 was delivered on August 18 2000.

An updated version of the technical note was delivered mid-March. An updated version of TN 2 (Satellite anomaly analysis module) version 0.2 was submitted 3 April 2000.

WP230 Development of SAAM

Data plotter routine and the superposed epoch analysis module are running.

More tools, such as entropy analysis, help functions and typical values will be implemented in the analysis module in the near future for beta release.

A password protected beta version of SAAM is available to some of the operators.

WP240 Testing and demonstration of SAAM with new data

Started T0+17

WP305 Prototype of Satellite Anomaly Prediction Module, SAPM

The prototype was installed on the server in April 1999.

WP310 URD for SAPM

The User Requirements Document URD W P310 draft version 1 was delivered on 17 November 1999.

WP320 SRD for SAP

The SRD Version 1.0 was delivered on August 18 2000.

The technical note TN 3 (Satellite anomaly prediction module) version 0.2 was delivered on 17 January 2000.

WP330 Development of SAPM

Anomaly sets will be analyzed with entropy methods to determine the most relevant parameters for each anomaly data set. Solar wind parameters (n, v, B), position, time, and magnetosphere data (GOES >0.6 MeV, > 2 MeV, Kp, Dst, LANL 10 keV and100 keV) will be tested.

A systematic study will first be done using one anomaly data set and be continued by training neutral networks and implemented on the web. Anomaly classes will be defined based on the outcome of the tests. The results will be presented in Technical Note 3.

WP340 Testing and demonstration of SAPM

Started T0+19.
