影響GEO衛(wèi)星長(zhǎng)壽命高可靠的空間環(huán)境因素及其評(píng)估、驗(yàn)證和保障技術(shù)研究

摘要: 文章敘述了空間環(huán)境與衛(wèi)星長(zhǎng)壽命高可靠的關(guān)系，著重分析了影響GEO衛(wèi)星長(zhǎng)壽命高可靠的各種空間環(huán)境效應(yīng)，如：地磁亞暴電子造成的衛(wèi)星表面帶電及誘導(dǎo)的二次放電、輻射帶高能電子引起衛(wèi)星內(nèi)帶電、太陽(yáng)耀斑質(zhì)子和銀河宇宙射線(xiàn)造成的單粒子效應(yīng)、空間帶電粒子和太陽(yáng)電磁輻照造成的輻照總劑量效應(yīng)以及空間環(huán)境下敏感表面的污染效應(yīng)等。文章最后給出GEO衛(wèi)星空間環(huán)境效應(yīng)的評(píng)估、驗(yàn)證和保障技術(shù)研究的必要性及其主要研究方向。

Abstract: The relation between the space environment and the life and reliability of satellites is discussed by analyzing various influencing factors. Space substorm environment is related to satellite surface charging and discharging; high energy electrons in belt cause satellite internal charging; solar and particle event and galactic cosmic ray induce single event effects; space charged particles and solar electromagnetic radiation produce a total dose effect; and space vacuum environment influences the satellite self-contamination. The evaluation, verification and guarantee technologies of these space environmental effects are also discussed.
