Phys.org  October 27, 2021 Plasma in the ionosphere plays a significant role in reflecting and modifying radio waves used for communication and radio navigation systems such as GPS, but the accuracy of these can be affected by ‘space weather’ events such as solar storms. The space weather events dynamically increase the total number of ionospheric electrons; GPS systems cannot correctly model this dynamic enhancement and errors occur in position calculations. An international team of researchers (UK, Norway, Portugal) conducted a controlled radar wave experiment by injecting radio waves into the ionosphere, at slightly different frequencies. By annlyzing the returned signals […]
