This report summarizes the project activities that have been performed within the project Robust positioning systems during 2014. Seen from a technical perspective, the work is focused on two research areas that have the potential to improve the accuracy and robustness of military positioning systems: (i) cooperative localization where the platforms work together and exchange information, and (ii) global satellite navigation system (GNSS) receivers that use civil and military GNSS-signals and that are able to detect deliberate jamming or spoofing attacks. The project activities are as follows: - Analysis of the need for improved robustness, and the technical possibilities to achieve this, for selected military platforms. - Design, evaluations and demonstrations of algorithms and technologies that can improve the robustness of GNSS-receivers and strategies for cooperative localization approaches. - Maintain knowledge concerning future soldier positioning systems. - Information dissemination. The pre-study concerning different platforms requirements and needs is delayed and will be finished during next year. The technically focused activities progress according to plan, and we have performed more work than initially planned on cooperative localization schemes.
