“…However, for the location of containers, the accuracy, availability and integrity of these stand-alone systems is insufficient. To obtain the required performance, augmentation systems are used such as the EGNOS (European Geostationary Navigation Overlay Service) or LAAS (Local Area Augmentation System) systems (Lechner and Baumann, 2000).…”

Most of the fruit in Europe is transported by road, but the saturation of the major arteries, the increased demand for freight transport, and environmental concerns all indicate there is a need to change this means of transport. A combination of transport modes using universal containers is one of the solutions proposed: this is known as intermodal transport. Tracking the transport of fruit in reefer containers along the supply chain is the means by which product quality can be guaranteed. The integration of emerging information technologies can now provide real-time status updates. This paper reviews the literature and the latest technologies in this area as part of a national project. Particular emphasis is placed on multiplexed digital communication technologies and wireless sensor networks.

RESUMODados de focos de calor via satélites ambientais, de Sistemas Frontais (SF) e Zona de Convergência do Atlântico Sul (ZCAS), juntamente com o Standardized Precipitation Index (SPI) e os Relatórios de Ocorrência de Incêndios (ROI) no Parque Nacional do Itatiaia (PNI) foram avaliados. O SPI foi calculado com dados pluviométricos de três estações no PNI. Os dados dos SF e ZCAS foram obtidos via Climanálise. A regressão múltipla foi aplicada a ROI, SPI, SF e ZCAS de forma independente. A maior categoria do ROI ocorreu na classe C (81%), sendo os maiores percentuais no inverno (57,2%) e primavera (35,1%). Os meses críticos de focos de calor foram julho (17%), setembro (23,2%) e agosto (31,9%). Independente da estação, o SF (R2 = 0,75) se sobressaiu em relação a ZCAS (R2 = 0,43). O SF condiciona 80% das variações entre ROI e índice SPI anual, enquanto a ZCAS em apenas 40%.Palavras-chaves: sistemas produtores de chuva, incêndios florestais, índice de seca. Relationship Between Standardized Precipitation Index (SPI) and the FireOccurrence Reports (FOR) in Itatiaia National Park ABSTRACTWe evaluated fire foci data via environmental satellites, from Frontal Systems (FS) and South Atlantic Convergence Zone (SACZ) together with Standardized Precipitation Index (SPI) and Fire Occurrence Reports (FOR) in Itatiaia National Park (INP). SPI were computed with rainfall data from three stations in INP. SF and SACZ data were obtained via Climanálise. We applied independent multiple regression to FOR, SPI, SF and SACZ. Largest FOR occurred category in C class (81%), highest percentages during winter (57.2%) and spring (35.1%). The critical months to fire foci were July (17%), September (23.2%) and August (31.9%). Regardless of the season, FS (R 2 = 0.75) were highlighted to SACZ (R 2 = 0.43). SF conditioned 80% of variations between FOR and annual SPI index, while only 40% were due to SACZ.

“…The navigation systems provided by engineering advances in satellite technologies were initially the NAVSTAR GPS (Navigation System with Time and Ranging -Global Positioning System) developed and maintained by the U.S. Department of Defense and Transportation, and the Russian Global Navigation Satellite System GLONASS (Globaluaya Navigatsionnaya Sputnikovaya Sistema) [7] . Although both are national military systems, they were available for use by the international private and commercial communities [8,9] .…”

Attention is here focused on the concept that the development of smart cities can also be achieved by improving the efficiency of civil infrastructures through a real-time monitoring. This is the specific target of the European Union FP7 project (SPARTACUS), moved from the parallel chance to develop industry pull applications for the European EGNOS and GALILEO satellite systems. In this paper, laboratory tests are carried out to provide specific devices the ability to run while satisfying the requirements of the incoming GALILEO system. Moreover, some of the targets are achieved within the current GPS system. An extensive experimental campaign is offered to validate the units in such a scenario. Keywords: smart cities, asset tracking, security, positioning, data transmission, GNSS
