The ionosphere, the ionized part of Earth's upper atmosphere, can significantly affect the radiowave propagation in many ways (refraction, reflection, Faraday rotation, and amplitude and phase fluctuations). Moreover, in Canada's northern regions, commercial and private aircraft rely on the high-frequency communication links and are seriously affected by the variations of the electron density. Therefore knowledge of the ionospheric electron density and the structures in it are essential for forecasting and mitigating the effects upon radio signal for application oriented systems such as communication and navigation. Precision monitoring of the structures in the electron density of the ionosphere will also have significant implications in almost all areas of the GPS user community (navigation, control segment, and monitoring systems).

电离层是地球上层大气的电离部分，它可以以多种方式（折射、反射、法拉第旋转以及振幅和相位波动）显著影响无线电波的传播。此外，在加拿大的北方地区，商业和私人飞机依赖于高频通信链路，并受到电子密度变化的严重影响。因此，了解电离层电子密度及其结构，对于预测和减轻对通信和导航等面向应用的系统的无线电信号的影响至关重要。 对电离层电子密度结构的精确监测还将对全球定位系统用户群体的几乎所有领域（导航、控制部分和监测系统）产生重大影响。
