A description, pertinent to the HF communications engineer, of the high latitude ionosphere is given. The impact of this disturbed geophysical environment on communications systems is described, and some frequency management techniques to avoid potential system outages are outlined. Reference is made to long term ionospheric predictions and short term ionospheric forecasts.

Inspec keywords: radio systems; radiowave propagation; ionospheric electromagnetic wave propagation

Other keywords: system outages; short term ionospheric forecasts; high latitude ionosphere; morphology; radio systems; long term ionospheric predictions; frequency management; radiowave propagation; disturbed geophysical environment; HF communications systems

Subjects: Ionospheric electromagnetic wave propagation; Radiowave propagation; Radio links and equipment
