Polar Research Ionospheric Doppler Experiment

Scientific objectives
The Polar Research Ionospheric Doppler Experiment (PRIDE) project uses a low power (20W), single frequency HF transmitter, located at the Polish Research Base in Hornsund, that transmits a signal into the ionized part of the upper atmosphere (the ionosphere), where it is reflected at an altitude of ~200km before being received at the Kjell Henriksen Observatory in Longyearbyen.

The reflection altitude will change depending on various ionospheric processes such as Gravity Waves or ULF (Ultra Low Frequency) waves. This change in altitude will be registered as a doppler shift of the received signal. The experiment will allow us to continuously monitor the wave structures in the ionosphere (magnitude, frequency, local time dependence, geomagnetic dependence..) which can provide information about various energy transfer processes.
