Electro-magnetic emission of power line communiation system: Intended or not intended radiation?

Abstract: The nature of the Power Line Communication (PLC) equipment is complex because it is considered as an information equipment for Electro-Magnetic Compatibility (EMC) standardization, but it is used to inject High-Frequency (HF) and Very High Frequency (VHF) frequency signals on the existing power network which is not designed to guide these frequencies. This PLC system issue leads to some difficulty to finalize EMC standardization of PLC equipment. This paper shows some EMC issues due to the parasitic radiation of HF and VHF PLC systems. An original method using radiofrequency analysis is used to demonstrate that power lines act as antennas for PLC frequencies, as if the PLC system was a radiofrequency system. So, we can define the PLC system as a “not intended radiofrequency system”, i.e. a family product which have to comply not only with EMC standards but also with Radio Equipment Directive (RED) system.

Sensor Tasking Management in a networked force

Abstract: Sensor tasking management (STM) is a concept that has been under development at Thales Netherlands for a number of years. This work was driven by the observation that, for several reasons, it has become increasingly complicated for the human operator to manage and control a sensor (suite) on-board of a naval platform.

Towards the single European EMC defence standard AECTP 250-500, and planned updates

Abstract: The European Commission is supporting one European wide defence (equipment) market, and national standards are preventing such a European-wide approach. Therefore the European Standardisation organisation CEN was asked to create an organisation to rationalize standards for defence procurement. Expert Group 7 was on electromagnetic environmental effects (E3), and especially EMC, while Expert group 15 was on Power Quality. The expert groups delivered databases and reports. In 2009 the European Directive on Defence Procurement was published. This gives a clear preference for international standards: National standards shall not be used in contracts anymore. The preferred standard for defence equipment will be the STANAG 4370, AECTP 500 series. This paper presents the present status and planned updates.
