Spacecraft Design - In-orbit verification


The weekly averaged electron flux spectrum
as measured by PROBA-V/EPT at LEO

The service "Spacecraft Design - In-orbit verification" aims to provide a best estimate of the local environment that has been experienced by a spacecraft either through measurements or reconstruction for in-flight validation of environment specifications (i.e. ionising radiation, plasma, microparticles, atmosphere, and UV) and consequent effects (e.g. dose, single event upset, sensor background, cumulated charge, spacecraft anomalies, microparticle impacts).

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 ESA Space Weather Service 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 set of models and in-orbit sensor datasets are provided 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 planning;
  • 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 Satellite Risk Indicators Forecast (SaRIF) provides colour-coded risk indicators showing the risk from internal charging and total ionising dose for the outer radiation belt and slot region, as well as a recontruction of these environments;
  • the Space Weather Data Browsing and Analysis (SWE Data) provides access to space weather environment data.

Spacecraft need to be able to withstand the effects that the multitude range of phenomena (e.g. solar flares, coronal mass ejections, solar energetic particle events) in the dynamic space environment may have on technology. The goal of spacecraft radiation shielding is to protect the crew and hardware (exterior and interior) from the radiation environment encountered in space. When designing and building a spacecraft both short- and long-term cumulative effects must be considered. The development and improvement of models providing environment specifications and effects predictions is an important aspect in advancing the design of future efficient shielding. A number of tools and products can be used to generated the environment specifications which can then be compared with the available measurement data.

The minimum environmental standards as defined in the Space Environment Standard ECSS-E-ST-10-04 (see Auxiliary Info) are implemented in the Space Environment Information System (SPENVIS) tool. The space environment for a specific orbit can be obtained based on these and other models in order to compare them with observations. Both the model outputs and measurements can be used to evaluate the various effects on the specific hardware defined by the user.

Other models that can be accessed through the portal are: the UTU-SEP products comprising a high energy SEP event list, and high energy proton fluence and peak flux models for a specific mission length due to SEPs; the MSSL electron population model at MEO and GEO as function of solar wind speed and Kp index; and the SPM dynamical simulation providing the number density and temperatures of electrons in the plasmasphere as a function of time and Kp index.

Specific particle radiation data provided through the network are based on the measurements from the Energetic Particle Telescope (EPT) on PROBA-V, and from the Standard Radiation Environment Monitors (SREM) on Proba-1, Integral, Rosetta, Herschel and Planck. Time series of the energetic electron, proton and helium fluxes as measured by EPT are available, as well as weekly geographical flux maps for each particle species and energy channel. Weekly energy spectra are provided for auroral electrons as well as proton and helium in the South Atlantic Anomaly. Daily radiation situation reports based on the SREM data in several key regions along the orbit of the various spacecraft are provided. Daily measurements of particle radiation levels and spectra are compared with reference models for the proton and electron belts, the slot region, and interplanetary space. The Solar Energetic Particle Environment Modelling (SEPEM) application server provides a reference event list for solar energetic protons, a reference data set for protons and helium, and tools to perform solar energetic particle statistical analyses on an extended set of cross-calibrated data. Besides forecasts for spacecraft effects and the radiation environment for the outer radiation belt and slot region, the SaRIF product also provides a post event reconstruction for the energetic electron spectra in those regions based on the BAS-RBM model.

Furthermore, the SEDAT (Space Environment DATa system) tool 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.

When interested in the impact of microparticles, the European Debris Impact Database (EDID) could be accessed which has a large database of events measured from debris and meteoroid impact detectors together with includes spacecraft housekeeping data.

The user who is interested in an overview of the typical programmatic concerns related to the space environment is invited to visit the service page for "Spacecraft Design - Environment specification: data archive".

                                          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.

                                          The Space Research Laboratory Solar Energetic Particles (UTU-SEP) products consist of several tools to calculate expected very high-energy solar energetic particle environment specifications for mission durations between 0.5 and 7 years: cumulative and worst-case event fluences for very high-energy (10-1000 MeV) protons, peak flux for very high-energy (330-700 MeV) protons, cumulative and worst-case fluences for high-energy (13-100 MeV/n) heavy ions. A catalogue of SEP events based on SOHO/ERNE observations of 55-80 MeV protons is also provided containing information on event start and end times (protons and electrons), peak intensity (high-energy protons and electrons), proton and heavy ion fluence, and information on associated solar flares and CMEs.

                                          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.

                                          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.

                                          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.
