In November 2009, the European Space Agency (ESA) launched its first-ever Soil Moisture and Ocean Salinity (SMOS) satellite to measure global soil-moisture levels. The satellite’s radiometer surveys 50 x 50 kilometers areas, using the detection of microwave emissions from land and water to construct global maps of moisture and ocean salinity. Scientists planned to use the data … [Read more...]
Rugged Embedded DC-DC Power Supply Boards Introduced for Military
Parvus Corporation, a developer of military electronic components and systems, has introduced two rugged embedded DC-DC power supply boards with built-in MIL-STF power conditioning and electromagnetic interference (EMI) filtering to be used for embedded computing applications in military aircraft and ground vehicles.

New Service Stops Interference of Wireless Devices with Military Radar
One of the world's leading experts in product testing and certification, TÜV SÜD Product Service, launched the United Kingdom’s first Dynamic Frequency Selection (DFS) service that utilizes a single-test platform. The new single-test platform was designed and made in the UK by Aeroflex. The new TÜV SÜD system is up to 60 percent faster than traditional methods of DFS testing … [Read more...]
EMI/EMC Testing on Mission Observatory
EMI and EMC testing is being conducted at Orbital Science Corporation in Gilbert, Ariz., to validate that while the Landsat Data Continuity Mission Observatory is in space, all components will function together efficiently. After EMI/EMC testing is finished successfully, the observatory will be prepared for mechanical tests next month to ensure it will survive the launch … [Read more...]
FAA Considers Digital Device Usage on Planes
The Federal Aviation Administration has announced the formation of a government-industry group to study the current policies and procedures aircraft operators use to determine when portable electronic devices (PEDs) can be used safely during flight. Current regulations require an aircraft operator to determine that radio frequency interference from PEDs are not a flight safety … [Read more...]
Space Satellite to Improve Telecom Completes EMC Testing
Sierra Nevada Corporation’s Space Systems has successfully completed critical EMC testing of ORBCOMM Inc.’s Generation 2 (OG2) prototype satellite. The ORBCOMM OG2 will serve as a prototype for a total of 18 new satellites that will constitute the company’s second generation satellite network. They are designed to improve telecommunication services as well as collect Automatic … [Read more...]
EMI/RFI Portable Shielded Enclosure at NASA Jet Lab
The first U.S.-based clean room acceptable EMI/RFI portable shielded enclosure, has been completed and deployed in a class 1000 clean room at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. It is now in service to test and run diagnostics on the Mars Science Laboratory Rover and other spacecraft. The new EMI test chamber is 9,375 cubic feet in size with an inside … [Read more...]
Physicist Uses Surfboards to Create Electromagnetic Invisibility Cloak
A University of Exeter scientist, Dr. Matt Lockyear, is using foam from inside surfboards to make a material that refracts light to create an “invisibility cloak.” The long sought after invisibility cloak of particular interest to the aerospace industry is a material that is uniformly dense and in response to electromagnetic radiation, behaves in a similar way to air. Dr. … [Read more...]
New Magnetic Field Coil Generates Fields up to 1200 A/m
Teseq, a provider of instrumentation and systems for EMC emission and immunity testing, has introduced a new magnetic field coil that generates fields up to 1200 A/m during magnetic field testing. The INA 703 is designed for testing to IEC 61000-4-8 (supply frequency magnetic fields), IEC 61000-4-9 (pulsed magnetic fields) and IEC 61000-4-10 (oscillatory magnetic fields) … [Read more...]
Band Pass Filter Chip With User Selectable Passband Frequency
Hittite Microwave Corporation introduced the HMC897, a new band pass tunable filter chip that is ideal for pre-selection in advanced communications systems, military radar, EW/ECM, SATCOM, space, industrial and medical systems. Tunable over a 9 to 19 GHz frequency range, this new, ultra-compact, varactor-tuned MMIC filter is inherently stable and has small physical size and … [Read more...]
