Every day the general public use GNSS systems to navigate their cars and boats, businesses rely on GNSS for timing networks and high accuracy positioning is used for surveying.

However there are natural phenomena which serve to degrade the performance of these systems, their accuracy and reliability. In this one day workshop we will be looking at the effects of:

• Sunspots, Solar flares, Solar maximum
• Multipath
• Environmental impact on satellite orbits

We will find out what causes these problems and how they ultimately impact on the navigation or positioning performance of your GNSS receivers. We will hear from both academics and industry professionals and seek to understand if all receivers will be influenced in the same way, or will different types of receiver cope with the challenges differently. How can these phenomena be mitigated against using novel designs and software techniques? Are the effects the same across the globe?
