University Centre in Svalbard (UNIS)

Scientific objectives
The main objective is to obtain vertical electron density profiles in the polar ionosphere using an HF radar. The signatures in the measurements can be associated with phenomena such as polar cap absorption, polar cap patches and plasma convection. An ionosonde complements the optical instruments at KHO as well as the SuperDARN and EISCAT Svalbard Radars.

The Longyearbyen ionosonde uses a software-defined radio and pseudo-random pulse coding, which allows very small transmit powers (typically 0.5W) to be used. The software is open source and the hardware uses commonly available off-the-shelf components.
