IZT Unveils Next Generation of its High Performance Receivers IZT GmbH expands its powerful RF receiver family introducing the IZT R5000. The next generation of high performance receivers combines up to 100 MHz instantaneous bandwidth with the proven excellent RF performance of the legacy IZT receivers. The R5000 covers the frequency range between 9 kHz and 18 GHz. Received signals will be available as high resolution spectrumdata in combination with up to four configurable wideband I/Q data channels with user configurable sample rates and independent center frequencies. The wideband channels provide I/Q data between 5 MHz and 100 MHz bandwidth. Additional 32 channels with up to 4 MHz bandwidth each can be used for narrowband monitoring, demodulation or analysis functionality in software. A dual 10-Gbit optical interface ensures adequate throughput in all operational scenarios. The IZT R5000 gives system integrators direct access to the control and data interfaces, where the received RF signals will be available both in IQ and PSD format. When combined with the IZT Signal Suite Software, the new RF receiver also supports IZT’s patented technique for frequency selective and dynamic recording of active portions of the spectrum. This feature results in a substantial reduction of required storage space. “This new family of receivers uses latest digital signal processing technologies on a compact and robust hardware platform. This puts IZT in a leading position to address demanding applications, for example airborne direction finders or unattended outdoor nodes for spectrum monitoring or Time-Difference-Of-Arrival location finding” stated Rainer Perthold, CEO of IZT. The IZT R5000 can be configured for TDOA (Time- Difference-Of-Arrival) and DF (Direction Finding) applications. Like the IZT R3000, the IZT R5000 series will be available in various configurations andmechanical form factors ranging from rack-based, single channel indoor applications to multi-channel direction finding receivers for outdoor or airborne applications. Availability The receivers will be available in late 2016. Initial models include both a 19-inch 1U unit for rack-based installations and a rugged mechanical variant for harsh

BAE Systems develops laser airspeed sensor for aircrafts In an aviation first, British scientists in Chelmsford have successfully trialled a highly accurate laser airspeed sensor for use in the next generation of high altitude aircraft which will increase survivability while improving performance and fuel efficiency. The Laser Air Speed Sensing Instrument (LASSI) which is being exhibited at this year’s Farnborough International Airshow sets itself apart from conventional methods as it accurately measures velocity even at low speeds. Conventionally, air speed is determined using pitot tubes – which protrude from aircraft and sense variations in air pressure with speed. Although usually heated, these tubes are vulnerable to blockage in icy conditions. They could also be damaged by collisions with birds and when the aircraft is on the ground. Operating on the same principle as roadside speed- guns, the new technique works by bouncing ultraviolet laser light off air molecules and measuring the change in ‘colour’ of the reflections caused by the Doppler Effect*. In layman’s terms, the further away from the ultraviolet light the reflection is, the faster the aircraft is travelling. Although invisible to the human eye, the detector can identify minute changes in colour – which indicate the aircraft’s airspeed. Dr Leslie Laycock, Executive Scientist at BAE Systems said, “LASSI is a ground-breaking piece of technology which is challenging the conventional method of measuring air speed. “Conventional air data sensors which protrude from the sides of aircraft must be carefully located to work
