Figure 1 The Precalculate Process architecture this method mitigates the risk that hostile forces may try to jam the UAVs radio control Moreover radio silence can be realized which is beneficial or even required for some missions No dedicated security module required on the user terminal no SWaP problems no keying issues no handling of controlled items on user side no need for a communication link giving rise to the availability and radio silence issues and no security issues Images Fraunhofer IIS JANUARY 2019 WWW GPSWORLD COM GPS WORLD 45 SPOOFING RESISTANT UAVS BY Alexander Rügamer Daniel Rubino Xabier Zubizarreta Wolfgang Felber Fraunhofer IIS and Jan Wendel and Daniel Pfaffelhuber Airbus Defense and Space GmbH T his work presents a new secure localization method that can be used for UAVs to obtain a new level of protection against hostile and unauthorized UAVs While non spreading code encrypted SCE GNSS devices can be blocked authorized UAVs using this method have unrestricted access to the nonspoofable and trusted SCE GNSS The proposed method is to store short sequences of SCE PRN code chips on the user receiver before the mission These SCE PRN code chips allow the user receiver to calculate at predefined points in time a secure and trustable SCE PVT position Since no communication channel is required FLAMINGO FULFILLING ENHANCED LOCATION ACCURACY WITH INITIAL GALILEO SERVICES BY William Roberts Joshua Critchley Marrows Marco Fortunato Maria Ivanovici Nottingham scientific Ltd Karel Callewaert Thiago Tavares VVA Brussels Laurent Arzel and Axelle Pomies Telespazio France due to the short SCE PRN code chip sequences valid only for the limited mission duration and inside a limited area Potential target markets for this method are police and special forces and other authorized users which are allowed to use certain SCE GNSS and would like to equip their UAVs with a secure unspoofable positioning solution More info at www ion org publications browse cfm T he FLAMINGO initiative is developing the infrastructure solutions and services to enable use of accurate precise GNSS in the mass market operating predominantly in an urban environment Whilst mass market receivers are yet to achieve accuracies below one meter for standard positioning the introduction of Android raw GNSS measurements and the Broadcom dual frequency chipset present such an opportunity FLAMINGO will enable high accuracy positioning and navigation information on devices such as smartphones and internet of things IoT devices by producing a service delivering accuracies of 50 cm at 95 and better employing multi constellation PPP and RTK mechanisms power consumption optimisation techniques Whereas the Galileo High Accuracy Service targets 10 cm precision for professional users FLAMINGO targets 50 cm precision for consumers With accuracies of a few decimetres a range of improved and new applications in diverse market sectors are introduced including but are not limited to mapping and GIS autonomous vehicles augmented reality environments location based gaming and people tracking To obtain such high accuracies with mass market devices FLAMINGO must overcome several challenges which are technical operational and environmental This includes the hardware capabilities of most mass market devices where components such as antennas and processors are prioritised for other purposes We demonstrate that despite these challenges FLAMINGO has the potential to meet the accuracy required Tests with the current smartphones that provide access to multi constellation raw measurements the dual frequency Xiaomi Mi 8 and single frequency Samsung S8 and Huawei P10 demonstrate significant improvements to the PVT solution when processing using both RTK and PPP techniques More info at www ion org publications browse cfm
