A free app for both iOS and Android features the results of European GNSS Agency (GSA) supported research and development initiatives. The new EGNSS Research and Development (R&D) application highlights the tangible results coming out of the 7th Framework Programme (FP7) and is designed to serve as inspiration for those participating in the Horizon 2020 (H2020) period. The FP7 and H2020 programs, supported by the GSA, aim to support the development of EGNSS applications in key market segments. Both are geared towards accelerating the development of a European market for satellite navigation applications and creating new opportunities for European industry. “The app is an excellent opportunity for the GNSS community to take stock in the lessons learned during the FP7 funding period and set our sights on future R&D initiatives,” said GSA Executive Director Carlo des Dorides. “The application’s segment-specific search feature responds to the varied needs of our users, providing them with easily accessible and relevant information at their fingertips.” In addition to the search function, des Dorides notes that the demographics included with each project can help users identify opportunities for partnerships across segments and regions, and create virtual R&D networks. The FP7 programmes had a considerably positive impact on the GNSS market, GSA said (download the brochure). Within the frame of the projects, 45 products were developed, and 80 prototypes were tested and validated during the 115 demonstrations that took place. Today, Horizon 2020 is bringing new opportunities for GNSS applications development. Information on the 25 projects granted in the first H2020 Galileo call is already included in the application, and early next year it will be updated to include the 2nd call portfolio of projects. The app is available for free download from the iTunes and Google Play stores.
