SWIGPOD: Evolution of the GNSS performance indicators aimed at end users' needs

Kurzfassung

This fall marked the start of the ESA S2P-S1-SW-21 SWIGPOD project which is devoted to extensively upgrade the GNSS Performance Indicators also taking advantage of the newly introduced ESA SWESNET products. Space Weather has significant impact on wide range of GNSS-based modern technologies and also critical infrastructures, which is reported mostly during Solar Maxima and accordingly many GNSS user communities experienced the significant effects of the May 2024 events. The Space Weather Service providers are thus asked to provide simple to understand, but accurate nowcasting or ideally forecasting services for various use cases and user communities. The range of interested GNSS users are invited to consultations of the planned service improvements which are ought to be well aimed from the users point of view. Therefore, all the other GNSS services users are welcome to share their experience and challenges associated with degradation of GNSS services so that the products can be tailored also to their needs which will be also further configurable to specific ionospheric impact sensitivities. The new SWIGPOD warning system will gather relevant real-time monitoring and partially forecasting services based on the use-case-driven synthesis of the SWESNET products. Alhough focused on GNSS, SWIGPOD will provide also indicator for radioastronomy end-users like LOw Frequency ARray (LOFAR) telescope for suitable observing conditions, i.e. disturbed by the ionosphere than the specifically obtained threshold as ionospheric hindcasts for purposes of LOFAR are applicable for selecting only suitable measurements for processing, which is very energy demanding.
