WP6 will address such themes in an harmonised way, promoting HELMET architecture and augmentation messages within existing GNSS Standardisation Organisations (e.g. RTCM SC-134 committee) and single sector bodies (ERTMS for rail, SAE for automotive). Regulation will be tickled contacting relevant stakeholders (e.g. ERA for rail and national ministries of transport). A harmonised business model, taking into account the common role of some service providers (e.g. multimodal augmentation service providers) will be elaborated.
