Taking into account the results from an exploratory study completed in 2010 (“GNSS contribution to next-generation global ionospheric modelling”), the present activity aims at identifying a suitable algorithm for generating 3-D TEC maps based on processing data in near-real time (several minutes to a few hours).This method must overcome the weaknesses identified in the previous activity, by exploring several alternative approaches identified before, and further alternatives to be explored in the initial stages of the current activity. The method must take into account the type of data that will be available for processing in NRT, typically multi-system GNSS data from ground and in-orbit receivers and optionally atmospheric sounding data and other inter-satellite links. The resulting algorithm will bring benefits to a wide variety of missions and applications, not restricted to GNSS by providing improved ionosphere corrections in near-real time. Candidate algorithms shall be prototyped to establish their stability and potential accuracy in a realistic scenario. Procurement Policy C1 : Activities in open competition limited to the-non-Large-System Integrators.
