Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may
occur.
Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
Radio - HF (high frequency) radio may be intermittent.
