Scintillating Performance GNSS and its satellite-based augmentation services are in for another bumpy ride as we sail towards the next solar maximum. Forecasting these events is a bit like predicting climate change: everyone agrees its happening but no can agree on the outcome. The optimists forecast nothing too spectacular; the pessimists predict something much more exciting. The late start for the current solar cycle - number 24 since counting began in 1755 - suggests that the solar maximum will now occur in May 2013 . However, the GNSS community will be feeling the impacts long before the maximum arrives and for long afterwards. This short article explores the cause of these cyclical events, their effect on GNSS and how the consequences can be mitigated and the risks managed.
