Revista Brasileira de Cartografia, 2020 Quando se almeja maior acurácia no posicionamento GNSS, é imprescindível a correção dos efeitos de ordem superior da refração ionosférica. O erro associado à ionosfera é diretamente proporcional ao conteúdo total de elétrons (Total Electron Content – TEC)

Dizhen xuebao利用美国喷气动力实验室（JPL）提供的全球电离层总电子含量（TEC）网格数据分析2018年5月28日吉林松原MS5.7地震空间电磁异常情况。通过算法对比确定滑动四分位法的优势，并利用该方法计算此次地震从震前14天至震后6天的电离层TEC异常变化的时间序列，结合空间环境和ΔTEC异常二维空间分布情况进一步分析，结果显示：① 极区磁亚爆强烈时段越靠近北部电离层扰动越强烈；② 震前TEC观测值先增大后减小，震后又回升，电离层异常幅度随着震中距的减小而增大；③ 电离层在空间分布上 ...
