This presentation overviews the development of a tool for the validation of ionosphere data assimilation systems using Global Navigation Satellite System (GNSS) positioning algorithms, such as Single Point Positioning (SPP) and Precise Point Positioning (PPP). Using GNSS positioning algorithms for validation of ionosphere data assimilation systems offers several advantages. First, it does not require observations to be reserved for independent validation, allowing for all available observations to be assimilated. Second, it provides a validation approach that is closer to user applications compared to, for example, direct validation against ionosphere observations. This presentation will discuss the advantages and disadvantages of using GNSS positioning algorithms as a method for validation of ionosphere data assimilation models. Preliminary results showing the use of GNSS positioning algorithms to validate different ionosphere data assimilation systems will also be presented.
