COSMO-SkyMed is an Earth Observation space program funded by the Italian Ministry of Research and Italian Ministry of Defence (It-MoD) and conducted by the Italian Space Agency (ASI) in conjunction with It-MoD, which was designed in order to fulfill Dual-Use requirements in terms of different needs of Defence and Civilian Users, such as different requirements in data products, system performances, security needs, response time, request priority management and data accessibility/confidentiality, being a pioneer program in the frame of the Civil and Military Space Duality and representing a reference for future Earth Observation space programs. Furthermore, COSMO-SkyMed was designed in order to achieve Interoperability, Expandability with respect to additional Defence and Civilian Partners and Multi-Mission features, which are the bases for the establishment of international cooperation programs that have been set up by ASI and It-MoD or are going-on, such as the Italian-French cooperation named ORFEO (Optical and Radar Federated Earth Observation) and the Italian-Argentinean cooperation named SIASGE (Sistema Ítalo Argentine de Satélites para la Gestión de Emergencias). In such a context, a significant example of successful COSMO-SkyMed international partnership is the recent French Defence User Ground Segment (F-DUGS) integration within COSMO-SkyMed system. The aim of this paper is to show the COSMO-SkyMed conceived architecture, the experienced operational implications collected in operating the system from the launch of the first COSMO-SkyMed satellite until the completion of the constellation and the integration of the French Partner into the system, highlighting the lessons learned and the experienced challenges to fulfill very innovative and demanding requirements.

COSMO-SkyMed is an Earth Observation space programme funded by the Italian Ministry of Research and Italian Ministry of Defence (It-MoD) and conducted by the Italian Space Agency (ASI) in conjunction with It-MoD. In November 2010 the fourth and last COSMO-SkyMed satellite was successfully launched and integrated into the constellation after the positive conclusion of the commissioning phase in January 2011. The four satellites are placed in the same sun-synchronous dawn-dusk frozen orbit, designed in such a way to fulfil dual needs and to optimize the performances for a wide range of Civilian applications (e.g. risks management, agriculture/forestry, marine/coastal, geology) and Defence applications (surveillance, intelligence, crisis management, mission planning). The baseline four-satellite constellation configuration foresees that the satellites are placed on the same orbital plane with a difference of 90, 180, 270 and 360 deg in their respective anomalies. Currently the orbital configuration is composed of three satellites (namely PFM, FM#2 and FM#4) placed with a difference of 0, 180, and 270 deg in their respective anomalies, while a fourth satellite (namely FM#3) is placed in a tandem-like configuration with FM#2 (i.e. one-day temporal decorrelation). The aim of this paper is to analyze the orbital flexibility of COSMO-SkyMed constellation by performing a survey of the possible orbital interferometric configurations which could be achieved by the full COSMO-SkyMed constellation (e.g. tandem, tandem-like, double one-day tandem configuration, etc), focusing on their main features (e.g. temporal decorrelation, degradation of the temporal performances respect to the nominal equi-phased configuration, etc), providing a preliminary quantitative assessment of the interferometric products quality performance.

The Payload Data Handling and Transmission (PDHT) is a subsystem operating on board Earth observation satellites to provide handling and transmission to Ground of the data acquired by high resolution radar instruments, typically Synthetic Aperture Radar (SAR). The really challenging needs, according to the requirements stated by ASI and I-MoD, of the COSMO Second Generation (CSG) mission, requires very high performances in terms of SAR acquisition data rates and data volumes per orbit, leading to a Payload Data Handling and Transmission (PDHT) architecture design completely new with respect to the present flight proven solution. On the first generation of COSMO Sky-Med (CSK) satellites the SAR payload produces one data flow with a maximum rate of 600Mbps; on CSG the SAR is designed to simultaneously operate in dual polarization with an higher resolution, providing to the PDHT two input data flows with an overall input data rate almost quadruple of the CSK one. Therefore, a significant improvement of the state of art PDHT storage capability and downlink performances are resulted necessary. The competitive mission needs together with the availability of good technology maturity level and the consequent compatibility with the programme time schedule have driven the trade-off phase allowing the identification of a new and high performance technological and architectural PDHT solution. The baseline PDHT solution has been identified; it is designed with a faster data acquisition interface and with a new modulation and coding scheme, the 4D-TCM 8PSK with Reed Solomon and interleaving, to enhance spectral efficiency and to allow increasing the downlink capabilities (higher than 500Mbps). Details on the PDHT baseline architecture for high performance real time data handling and transmission in the frame of Cosmo Second Generation mission will be provided highlighting the main features in terms of architectural and technological aspects.

COSMO-SkyMed is a Dual-Use program, devoted to produce both civilian and military applications, and as such it is required to have a fast response time, to manage conflicts and to optimize resources. In order to provide operational continuity to COSMO-SkyMed mission, the Italian Space Agency (ASI) and Italian Ministry of Defense (It-MoD) are conceiving the next generation of the system. The new system, called "COSMO-SkyMed Seconda Generazione" (CSG), starting from the well established design of the first generation, will provide the end user with outstanding characteristics consolidating its position in the frame of SAR Systems. After a description of the current COSMO-SkyMed unique in-orbit performances, functionalities and Dual-Use operations, with examples of data already acquired in the last few years, the paper will introduce the CSG mission describing the main features and capabilities that will drive the design of the new system. © 2010 IEEE.

This paper describes the developmental and testing activities conducted by the Italian Air Force Official Test Centre (RSV) in collaboration with Alenia Aerospace, Litton Precision Products and Cranfiled University, in order to confer the Night Vision Imaging Systems (NVIS) capability to the Italian TORNADO IDS (Interdiction and Strike) and ECR (Electronic Combat and Reconnaissance) aircraft. The activities consisted of various Design, Development, Test and Evaluation (DDT&E) activities, including Night Vision Goggles (NVG) integration, cockpit instruments and external lighting modifications, as well as various ground test sessions and a total of eighteen flight test sorties. RSV and Litton Precision Products were responsible of coordinating and conducting the installation activities of the internal and external lights. Particularly, an iterative process was established, allowing an in-site rapid correction of the major deficiencies encountered during the ground and flight test sessions. Both single-ship (day/night) and formation (night) flights were performed, shared between the Test Crews involved in the activities, allowing for a redundant examination of the various test items by all participants. An innovative test matrix was developed and implemented by RSV for assessing the operational suitability and effectiveness of the various modifications implemented. Also important was definition of test criteria for Pilot and Weapon Systems Officer (WSO) workload assessment during the accomplishment of various operational tasks during NVG missions. Furthermore, the specific technical and operational elements required for evaluating the modified helmets were identified, allowing an exhaustive comparative evaluation of the two proposed solutions (i.e., HGU-55P and HGU-55G modified helmets). The results of the activities were very satisfactory. The initial compatibility problems encountered were progressively mitigated by incorporating modifications both in the front and rear cockpits at the various stages of the test campaign. This process allowed a considerable enhancement of the TORNADO NVIS configuration, giving a good medium-high level NVG operational capability to the aircraft. Further developments also include the design, integration and test of internal/external lighting for the Italian TORNADO "Mid Life Update" (MLU) and other programs, such as the AM-X aircraft internal/external lights modification/testing and the activities addressing low-altitude NVG operations with fast jets (e.g., TORNADO, AM-X, MB-339CD), a major issue being the safe ejection of aircrew with NVG and NVG modified helmets. Two options have been identified for solving this problem: namely the modification of the current Gentex HGU-55 helmets and the design of a new helmet incorporating a reliable NVG connection/disconnection device (i.e., a mechanical system fully integrated in the helmet frame), with embedded automatic disconnection capability in case of ejection. © 2012 SPIE.
