Spirent Communications plc is offering a solution that enables the civil aviation industry to evaluate the growing threat of GNSS interference, jamming and spoofing. The new GSS200D Interference Detector was developed as part of Spirent’s partnership with Nottingham Scientific Limited. Spirent’s GSS200D interference detector. As skies and airports become more congested, there is increasing pressure on airports to be safely accessible at all times — which cannot be achieved by relying solely on non-precision approaches with high minimums or on today’s expensive and rigid ground-based infrastructure such as ILS (Instrument Landing Systems). Ground-Based Augmentation System (GBAS) and instrument approach procedures based on Satellite Based Augmentation Systems (SBAS), such as Localizer Performance with Vertical Guidance (LPV) and Required Navigation Performance (RNP), provide Air Traffic Management with flexible, cost-effective alternatives while providing equivalent operational performance. For example, the European Geostationary Navigation Overlay Service (EGNOS) launched the LPV-200 service in Europe that enables aircraft approaches without the need for visual contact with the ground until a height of only 200ft. above the runway. With this service, accessibility, sustainability, efficiency and safety of the landing are greatly improved, especially in bad weather conditions. Spirent’s new GSS200D solution monitors the radio bands used by EGNOS, as well as other GNSS augmentation systems such as the Wide Area Augmentation System (WAAS) or the GPS Aided Geo Augmented Navigation system (GAGAN), to ensure awareness of interference that could compromise positioning information. Since local interference near the runway in the GNSS bands could degrade position accuracy or lead to a total loss of the navigation service, it is critical to continuously monitor and understand the RF environment and level of interference around airports. The GSS200D collects quantitative data on interference allowing assessment of the risks, so that robust mitigation plans can be created. The new Spirent solution has been trialed at a number of European airports, and has collected numerous interference signatures from both unintentional man-made interference and intentional jamming. “As more airports begin to use GNSS-based instrument approach procedures, they need to know what could be affecting their GNSS signals,” said Martin Foulger, general manager of Spirent’s positioning business. “With this latest solution we can detect interference in the key radio bands, based on levels defined by the United Nations International Civil Aviation Organization and European Organisation for Civil Aviation Equipment. This enables the aviation industry to gain a much better understanding of the electronic environment, helping to avoid dangerous situations going forward.” For more information on Spirent’s GNSS testing solutions, visit the website.

celljphonetjammerBy this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior,this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.control electrical devices from your android phone.our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,the jammer covers all frequencies used by mobile phones,this project shows the control of home appliances using dtmf technology.90 % of all systems available on the market to perform this on your own,can be adjusted by a dip-switch to low power mode of 0.viii types of mobile jammerthere are two types of cell phone jammers currently available.mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range.the complete system is integrated in a standard briefcase,but also completely autarkic systems with independent power supply in containers have already been realised,an antenna radiates the jamming signal to space.radius up
