The electromagnetic Radio Frequency environment which electro-explosive devices (EEDs) may experience in service and how this can affect the Hazards of Electromagnetic Radiation to Ordinance (HERO) safety are discussed. The uses for these types of devices in the aerospace industry are for both safety consequences and mission related systems. This paper discusses the different methods used for instrumenting EEDs in the past and presently, and the advantages and disadvantages of each type of instrumentation. Additionally, improvements that have been made in recent years are described, developing instrumentation techniques that are more reliable and repeatable with good sensitivities for each individual device and allow extrapolation of measurements. This paper also discusses the most common forms of instrumentation used today for testing in a High Intensity Radiated Field (HIRF) environment and where these methods were developed from.

Use of the VHF frequency band is becoming more common on modern telecommunication and earth observation satellites due to the relatively simple and low cost antennas, wide coverage and highly reliable communication links. Utilising the VHF band requires a significant effort in terms of electric field analysis to predict electromagnetic compatibility issues. EMC issues become critical for these applications due to the very high sensitivity of VHF receivers installed on the satellite. In this frame, Electromagnetic modeling is fundamental to identify potential risks and to reduce and optimize the number of tests at satellite level. This is a challenging task due the large number of equipments emitting in this range. The scope of this paper is to describe the approach followed on Copernicus Sentinel-1 C&D satellites to predict, by EM modeling tools: 1) the electric field levels generated by, and, on-board equipment inside the satellite cavity and, 2) the associated interfering power coupled to the victim antenna. The proposed approach has been implemented by the GALILEO-EMT[1] and can be also effectively extended to other frequency ranges using the proper electromagnetic solver suitable for each frequency band.

In this work, the test procedures and modeling results of low frequency (LF) electric and magnetic fields radiated by spacecraft equipment are implemented on near field measurements of the Command & Data Handling Management Unit (CDMU) of GOCE space mission. Specifically, the unit's LF electromagnetic signature is acquired up to 200 kHz and the frequencies that exhibit emissions are identified for both electric and magnetic field contributions. The measurements and modeling procedure are performed targeting to capture and characterize the steady state operation of the CDMU. The modeling methods presented in this work rely on measurements conducted in the frame of ESA's study on Pre-Verification of THOR Electro-Magnetic Cleanliness Approach.

Electromagnetically clean room is planned to be built in the Széchenyi István Geophysical Observatory in western Hungary. The environmental magnetic field will be reduced by five order of magnitude, which is well below the interplanetary magnetic field near the Earth. One of the application of the laboratory is to support magnetic cleanliness program for space equipments. Moreover, in particular for space applications, it is planned to develop, test and calibrate a new generation of magnetometers called SERF (Spin Exchange Relaxation-Free). Active compensation of the terrestrial field will be achieved by means of large coils with current determined from the actual field, which is measured through a magnetometer placed in the observatory. Passive shielding will be provided by a cube shaped room covered with two layers of mumetal. The novelty of the facility is that the two shielding techniques will be harmonized. To this purpose, detailed model calculations were performed in order to determine the best setup for the coils. The results of the numerical calculations show that the size of the compensating coils should be much larger than the size of the room covered with mumetal layers.

The coupling of plane waves with a specific time function, incident direction and polarization to a transmission line network (TLN) consisting of three single-wire transmission lines is investigated. The network is analyzed simulatively and experimentally in a GTEM cell. The coupled voltage to the TLN is investigated in frequency domain and in time domain. The investigation in time domain allows taking into account non-linear loads like diodes. The simulations were done in LTspice, a simulation tool for circuit simulation. The model is validated against an existing frequency domain solution for linear loads. Furthermore, both of the simulated results are compared to measured ones.

This paper presents the post-processing methodology devoted to the Near-Field-Scanning (NFS) to provide assistance in ElectroMagnetic Compatibility (EMC) design phases of complex electronics products. A major challenge for spacecraft manufacturers for incoming year concerns the control of units Radiated Emissions (RE). Indeed, high speed links could induce RE non-compliance for units in on-board receiver frequencies (ex: GPS, TCR…). To avoid additional test campaign or system level analyses, Near Field techniques could be a powerful way to anticipate RE non-conformities in unit design phase. Based both on NFS (only $H_{x}$ and $H_{y}$ magnetic components very closed to the Printed Circuit Board (PCB)), and on Shielding enclosure Effectiveness (SE) characterization, the proposed “NFS2RE” (Near Field Scanning to Radiated Emission Test) methodology allows: 1)RE-Test prediction of PCB in free space condition from only $H_{x}$ and $H_{y}$ NFS 2)Prediction of Shielding PCB's enclosure attenuation on RE-Test from SE characterization

This paper is about the Shielding Effectiveness (SE) measurement realized by THALES ALENIA SPACE in Toulouse on the microwave passive units and devices implemented into the communication module of the satellite payloads. In order to verify EMC design rules efficiency and the associated workmanship, these SE measurements are mandatory by the prime on all the microwave Flying Model units. Moreover, these SE measurements are also used to quantify the efficiency of the EMC design protections (Shielding gaskets or materials, interface connectors….) implemented on the RF (Radio Frequency) units during conception phase. These SE tests are performed using an oversized cavity called Mode Stirred Reverberation Chamber (MSRC) since 2007. Typical tests results and associated methodology are presented in this paper.

Some promising test procedures were recently developed as alternative approaches to radiated susceptibility (RS) verifications for unit-level test setups, with specific (but non-exclusive) reference to aerospace equipment. All test methods are based on the injection of conducted disturbances in the cable under test via suitable coupling devices and fall into two categories: a deterministic and a statistical equivalence scheme. While the former aims at the exact reproduction of RS effects, the latter enforces correlation of outcomes in statistical terms. In this paper, these different approaches are reviewed and critically discussed by the light of merit criteria including cost saving, training, intrusiveness, time consumption, complexity, repeatability and reproducibility, limitations of the equivalence.

This paper focuses on the development and the experimental validation of a physical-based model for the SpaceWire (SpW) cable (Variant 01) terminated by two micro D-type connectors. The model for the SpW cable relies on the frequency-dependent per-unit-length parameters computed from the available information of its cross-section and materials via a 2D simulation. On the other hand, the D-type connector model is obtained from the simulation results provided by its 3D representation in CST MICROWAVE STUDIO. The two models are then combined together and implemented in HSPICE by means of their circuit equivalents. The accuracy of the proposed models is then experimentally validated by considering the scattering parameters measured via an ad-hoc measurement setup.
