BS ISO 16709:2013 pdf free.Realtime solar activity and space environment information for spacecraft operation
Influence and concern to spacecraft operation: Solar flares and associating CME are major source of space environment disturbances. Generally, long duration and strong flares are thought to be important for risk evaluation on satellite operation.
Method for measurement or production: Flare information and listing based on satellites and ground-base observation available from public domain and reporting service
Category: GEO/MEO/L EO/Deep-Space
General description: SXR intensity measured by GOES radiated from full visible disk of the Sun. During flare,the intensity increase rapidly.
Influence and concern to spacecraft operation: SXR emission and Ha flares emissions and both are the widely used indicators of hazard harmful for space systems.
Method for measurement or production: In-situ measurement by satellite sensor and ground base observations of Ha flares.
Influence and concern to spacecraft operation: Solar X-ray radiation is the widely used indicator for solar activity level and flare and associating disturbance harmful for space systems.
Method for measurement or production: In-situ measurement by satllite sensor
General description: General description: lons accelerated to high energy by solar flare and/or by shock wave associated with CME propagation in solar corona and in deep space.I.
Influence and concern to spacecraft operation: Onboard computer malfunction due to upset of semiconductor devices, deterioration of SAP, electric devises, optical sensor etc…
Method for measurement or production: In-situ measurement by satellite sensor
Category: GEO/MEO/LEO
General description: Horizontal component geomagnetic field strength observed by ground based observation.
Planetary K index (Kp) is convenient for satellite operators
Influence and concern to spacecraft operation: Storm and sudden change of geomagnetic field is the cause of change of geo-space condition as a space system environment. Level and trend of Kp index is useful for general space environment risk evaluation.
Method for measurement or production: Ground based magnetometer observation network and its real-time data circulation.BS ISO 16709 pdf download.
