Spacecraft Design - Environment specification: data archive


Medium-term predictions of the smoothed monthly sunspot number obtained by applying an adaptative
Kalman filter to the primary methods.

The service "Spacecraft Design - Environment specification: data archive" aims to provide, for past or future spacecraft, statistical information on the space environment (i.e. ionising radiation, plasma, microparticles, atmosphere, and UV) and its effects (e.g. dose, single event upset, sensor background, cumulated charge, spacecraft anomalies, microparticle impacts), as well as long-term solar cycle prediction since several spacecraft effects exhibit solar cycle variation. Such information is needed for tailored design of space systems especially in relation to radiation protection, electromagnetic compatibility and microparticle impacts. The service is intended for personnel involved in generating space environment specifications for the design of spacecraft.

This service is implemented through a combination of products and tools which can be found through the following tabs along with expert support provided by the teams constituting the SWE Network. Should you require further guidance in the use of this service, or have specific questions about any aspects of the service presented here, don't hesitate to contact the Helpdesk.

A number of models and in-orbit sensor datasets are made available with the help of tools and products such as:

  • the Space Environment Information System (SPENVIS) coupling several empirical and engineering models of the space environment and its effects on spacecraft or components based on a mission plan;
  • the Space Environment Data System (SEDAT) allows engineering analyses to be carried out on datasets related to the spacecraft charged particle environments;
  • the Solar Energetic Particle Environment Modelling application (SEPEM) allowing solar energetic particle statistical analyses on an extended set of cross-calibrated data;
  • the European Debris Impact Database (EDID) provides data processing and dissemination functions for measurements from European debris and meteoroid impact detectors;
  • the Space Research Laboratory Solar Energetic Particles (UTU-SEP) products provide access to a high energy SEP event list as well as the calculation of the expected high energy proton fluence and worst-case proton flux for a specific mission length due to SEPs;
  • measurements and derived data products from the Energetic Particle Telescope (EPT) on PROBA-V;
  • measurements and derived data products from the Standard Radiation Environment Monitors (SREM) on Proba-1, Integral, Rosetta, Herschel and Planck;
  • the electron population model from Mullard Space Science Laboratory (MSSL) for LEO, MEO and GEO as function of solar wind speed and Kp index;
  • the SWIFF Plasmasphere Model (SPM) dynamical simulation provides the number density and temperatures of the electrons as a function of time;
  • the Space Weather Data Browsing and Analysis (SWE Data) provides access to space weather environment data.

The space environments considered include energetic particle radiation, plasmas, atmospheres, micro-particles, and contamination. They can all cause serious problems for space systems that need to be carefully taken into account during the development of spacecraft. The radiation environment, consisting of radiation belts, cosmic rays, and solar energetic particles causes effects such as radiation damage, single-event upsets in electronics, background in detectors, and health hazards to astronauts. The plasma environment increases electrostatic charging of spacecraft parts or affects scientific instruments. The residual upper atmosphere causes surface erosion by atomic oxygen. Finally the micro-meteoroids and space debris environments introduce significant risks for manned and unmanned spacecraft.

A possible starting point when preparing space environment specifications for a spacecraft design is the Space Environment Information System (SPENVIS). This tool allows the execution of a set of space environment models based on a mission scenario (mission duration, typical spacecraft trajectories and spacecraft attitude) and to evaluate impacts and risks by propagating the results into engineering models. The tool includes graphical visualisation and an extended help with background information and references to the European standards. For a more comprehensive analysis of the space environment effects, the SPENVIS output could be exported to more specific applications, such as GRAS (Geant4 Radiation Analysis for Space) or SPIS (Spacecraft Plasma Interaction Software), that are taking into account the detailed geometry of the spacecraft.

When the available models don't include the appropriate statistical information, a tool such as SEDAT (Space Environment DATa system) could be considered. SEDAT allows a wide range of engineering analyses to be carried out using a comprehensive set of in-situ space environment datasets. The flexibility of the tool authorises the tailoring of the data processing to the problem under study and the incorporation of new datasets.

The Space Environment Standard ECSS-E-ST-10-04 (see Auxiliary Info) provides principles for determining the local induced environment and guidelines for the model and parameter selection process. The table below summarises typical programmatic concerns related to the space environment.

                                                                          SPENVIS (Space Environment Information System) is a web-based interface for assessing the space environment and its effects on spacecraft systems and crews. The system is used for mission analysis and planning. SPENVIS includes several empirical models of the space environment covering mainly cosmic rays, solar energetic particles, the natural radiation belts, magnetic fields, space plasmas and the upper atmosphere. A range of engineering models are also available to help assess the effects of the space environment on spacecraft such as surface and internal charging, energy deposition, solar cell damage and SEU rates. Usually these later models take their inputs from the empirical models present in SPENVIS. The system also includes extensive background information on the space environment, the environment models and the related standards.

                                                                          SEDAT (Space Environment Data System) is a tool for the engineering analysis of spacecraft charged particle environments. The facility provides access to the ODI database containing a large and comprehensive set of data about that environment as measured in-situ by a number of space missions. The user can select a set of space environment data appropriate to the engineering problem under study. SEDAT also offers a set of software tools, which can operate on the data retrieved from the database. These tools allow the user to carry out a wide range of engineering analyses. SEDAT is using a GUI written in Java.

                                                                          SEPEM (Solar Energetic Particle Environment Modelling) is a WWW interface to solar energetic particle data and a range of modelling tools and functionalities intended to support space mission design. The system provides an implementation of several well known modelling methodologies, built on cleaned datasets. It also gives the user increased flexibility in his/her analysis and allows generation of mission integrated fluence statistics, peak flux statistics and other functionalities. It also integrates effects tools that calculate single event upset rates and radiation doses for a variety of scenarios.

                                                                          EDID (European Debris Impact Database) provides automated data processing and dissemination functions for measurements retrieved from European debris and meteoroids impact detectors.  It covers impacts from the DEBIE-1, DEBIE-2 and GORID detectors.  Users can access more than 3,000,000 debris and micro-meteoroid event records plus sensor and spacecraft housekeeping data via a user-friendly web interface.  Filters can be defined for each available parameter and be used for regular data retrieval.

                                                                          SWE Data is a web application that provides access to a wide range of Space Weather related data sources covering the areas of the spacecraft, ionospheric, and ground effects. SWE Data allows the user to access all data contained in the repository providing analysis and visualisation tools from these disparate sources.

                                                                          The AMDA system provides an archive of planetary, solar wind, Earth magnetosphere and ionosphere mission and ground based products. In addition it supports a range of standard models such as magnetic footprints, magnetic fields, solar wind propagation to planets and probes as well as access to external databases of observations and simulations. A key functionality of the system is its embedded plotting, data mining and cataloguing functionalities which are extremely useful in relation to posteriori analysis.
