One of the goals of the Ejército de Tierra (Spanish Army, SA) Operations Department is to ensure the operational availability of its numerous fleets of weapons' systems. Specially in times of economic crisis, with severe budget cuts, achieving this goal becomes a challenge for the logistic engineering, which has to look for efficiency by implementing innovative projects to improve its supply chain.Within the maintenance processes, the purchasing and distribution planning of spare-parts are considered the most relevant for the SA due to its influence in the operational availability and the enormous economical resources needed. Among other factors, the pattern of the spare parts demand, extremely irregular, erratic and with a large number of null periods, turns out that finding a good planning method is not a simple task. This article analyzes the implementation of the adapted RBS method ("Reliability Based Sparing") which provides SA a useful solution to the above purpose, diverting the attention from the demand of each single spare part to the whole system and the available credit. Satisfactory results after the first year of operation are presented.

This paper addresses the full lifecycle of security countermeasures identified in the Security Risk Analysis of the future Air Traffic Management System (ATM). The process establishes new security functions identified in the GAMMA project  and their implementations in order to ensure acceptable levels of security for ATM. In this project, ATM Security is addressed by focusing on two dimensions defined by Single European Sky ATM Research : establishing a collaborative support capability by defining a framework embracing three-levels for Security Management (i.e. European, National, and Local) and developing security measures for the self-protection/resilience of the ATM Systems by exploiting automated security-related functions to handle potential threats. This paper concentrates on the second dimension and how the countermeasures are identified, implemented and developed in prototypes. The prototypes will then be validated in an operational scenario, through the new concept introduced by the project. The reader will be accompanied through a practical example of the whole process on how ATM Security needs have been identified. The objective is to protect the core ATM Security functionalities (Primary Assets) and corresponding Supporting Assets. We identified 44 of the most feared threat scenarios in terms of impact on the SESAR Key Performance Areas (KPA). The threat scenario described in this paper is "False ATCO", affecting the Supporting Asset "Voice system". The developed prototype is "SACom" (Secure ATC Communication) that considers the security countermeasures identified in the risk treatment analysis to reduce the risks. The paper concludes with the description of the activities planned for validating the SACom prototype as part of the proposed global solution. © 2016 IEEE.

PAZ is the Spanish space based SAR system part of PNOTS program. PAZ instrument design is based on a new Xband Active Electronic Steering Antenna and recurrent platform and back-end electronics from TanDEM-X. In order to assure correct SAR system operation, CALVAL centre shall include instrument characterization/ calibration/verification capabilities mainly driven by engineering aspects inherited from precursors TerraSAR/ TanDEM-X. This paper summarizes PAZ instrument on-ground characterization and calibration results achieved in the frame of PAZ Ground segment CALVAL centre activities. Main results cover first on-ground antenna model validation, automatic TRM monitoring results, internal calibration analysis and a preliminary system performance budget update including latest characterisation results. © VDE VERLAG GMBH · Berlin · Offenbach, Germany.

The INTA Remote Sensing Laboratory has implemented a tool for the direct geolocation of satellite images. The core of the tool is a C code based on the "Earth Observation Mission CFI SW" from ESA. The tool accepts different types of inputs for satellite attitude (euler angles, quaternions, default attitude models). Satellite position can be provided either in ECEF or ECI coordinates. The line of sight of each individual detector is imported from an external file or is generated by the tool from camera parameters. Global DEM ACE2 is used to define ground intersection of the LOS. The tool has been already tailored for georeferencing images from the forthcoming Spanish Earth Observation mission SEOS at/Ingenio, and for the camera APIS onboard the INTA cubesat OPTOS. The next step is to configure it for the geolocation of Sentinel 2 L1b images. The tool has been internally validated by different means. This validation shows that the tool is suitable for georeferencing images from high spatial resolution missions. As part of the validation efforts, a code for simulating orbital info for LEO missions using EO-CFI has been produced.

A dosimeter for space applications is presented. It is based on the ionization damage affecting the TMP36 sensors when they are exposed to external radiation, which produces an increase of their output voltages. This work explains the configuration, sensing mechanism and working modes of this device and reports the results obtained in a gamma radiation test carried out in March 2012. The test results allow us to select the mode of operation that provides the highest response to the TID, as well as the most sensitive devices. The highest sensitivity is above 100 μV\rad. This dosimeter is part of The Two Towers radiation monitor that will fly on board of the SEOSAT-INGENIO satellite. © 1963-2012 IEEE.

The present paper describes the architecture, characteristics and first results of RBX, the new airborne SAR radar developed at INTA's facilities. RBX works in X-Band, having interferometric and polarimetric capabilities. Its measured ground resolution reaches the submetric range. The design of the system has taken into account several internal loops for calibration purposes, and its modular architecture allows easy upgrades of the radar. © VDE VERLAG GMBH · Berlin · Offenbach, Germany.

This paper describes an implemented solution to automatically detect and recognize in real-time both speed limit warning signs and speed limit signs in railway travel videos recorded from the driver's cab. The lack of available high-quality videos to train this kind of systems and the involved complexity of the rail scenes, with non-controlled illumination conditions, make it challenging the considered problem. Our framework achieved interesting recognition results of around 95% for both signs types and digits recognition. © 2016 IEEE.

This article presents a research that was aimed at developing a better understanding of current threats and how to conduct risk assessments in public transport networks by following generic guidelines that can be adapted according to each organization's needs. The aim is to facilitate the task of identifying threats and conduct a vulnerability analysis to help decision makers to prioritize resources in a systematic manner and consequently increase resilience. This article also highlights the main benefits and constraints of performing risk assessments and how the results of risk assessments can be used as a solid foundation for a structured, analytically clear, and systematic approach to security planning for a public transport network. In addition to the summary of the above research, a questionnaire was distributed among three main operators in Europe to gain more insight about the current state of the art in risk assessments in public transport systems. Key aspects of the research can be found presented as Guidelines for Users in the accompanying papers by Barr and Luyten. © Authors 2011.
