3D Aerospace with the support of its consortium, propose to develop a disruptive Localisation Based Service (LBS) through its Galileo-based project eMAPs to tackle the foreseen and expected smart city and autonomous car challenges. The proposed hardware and software developments of eMAPs aim at providing future solutions such as smart navigation for connected car users, real time fleet management for city public transport and infrastructure maintenance monitoring for city planners. By developing an innovative, low-cost, compact, high performance premium receiver, eMAPs will provide a targeted 30cm vehicle’s position accuracy and high definition urban maps which will benefit to all smart cities stakeholder groups: the travellers, the public transport operators and the urban authorities.
