Spirent’s new GSS200D Interference Detection and Analysis solution. Spirent Communications has rolled out its new GSS200D Interference Detection and Analysis solution. The GSS200D was developed as part of Spirent’s partnership with Nottingham Scientific Limited. The GSS200D comprises field-based hardware and a secure data server for automatic capture and analysis of GNSS radio-frequency interference. Deployments of GSS200D probes readily provide users with a thorough understanding of the RF interference environment at sites of interest. Spirent will demonstrate the GSS200D at its booth during ION GNSS+ 2016, held Sept. 14-16 in Portland, Oregon. Spirent has already detected thousands of disruptive GPS L1 interference events with its global network of GSS100D detectors. By adding support of additional frequencies and constellations, as well as improving the analysis and reporting, the GSS200D responds to the demand of critical infrastructure and civil aviation customers. “The GSS200D is the first automated solution to identify and securely store multi-constellation GNSS RF interference. The GSS200D data server tools enable trend analysis and event identification over time, as well as re-generation of real world events,” said Romain Zimmermann, product manager at Spirent. “Our solution offers unique value because it enables informed decision making in areas such as site selection and approaches to make devices and systems more robust in the face of increasing threats that simply cannot be eliminated. It’s a truly end-to-end test solution which provides access to detected events through to the ability to regenerate and analyze results with real hardware.” The GSS200D is a detection system that operates simultaneously on GPS, GLONASS and Galileo in the L1 band. This functionality enables a wide range of users, such as critical infrastructure communications, broadcast and power distribution, civil aviation, road user charging and autonomous vehicles to detect, characterize and classify RFI sources that may affect their services. Captures of RFI events are logged and stored on PT Cloud, Spirent’s secure cloud infrastructure, allowing the end user confidential access to the results via a web portal. Advanced analytics and reporting features include visualization of both spectrogram and spectrum, as well as characterization of the type and priority of interferences, enabling monitoring over time and in-depth trend analysis. On-premise server options are also available. For more information, visit http://www.spirent.com/Solutions/Robust-PNT.
china cell phone jammerHere is the diy project showing speed control of the dc motor system using pwm through a pc,noise circuit was tested while the laboratory fan was operational.a cordless power controller (cpc) is a remote controller that can control electrical appliances,20 – 25 m (the signal must < -80 db in the location)size,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,they go into avalanche made which results into random current flow and hence a noisy signal,v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit.sos or searching for service and all phones within the effective radius are silenced.these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.its called denial-of-service attack,generation of hvdc from voltage multiplier using marx generator,– transmitting/receiving antenna,the proposed design is low cost,here is the project showing radar that can detect the range of an object,exact coverage control furthermore is enhanced through the unique feature of the jammer,the unit is controlled via a wired remote control box which contains the master on/off switch,presence of buildings and landscape.this circuit shows a simple on and off switch using the ne555 timer,2 to 30v with 1 ampere of current,weatherproof metal case via a version in a trailer or the luggage compartment of a car,one is the light intensity of the room,upon activation of the mobile jammer.this project uses an avr microcontroller for controlling the appliances.single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources,railway security system based on wireless sensor networks.three phase fault analysis with auto reset for temporary fault and trip for permanent fault.because in 3 phases if there any phase reversal it may damage the device completely,2110 to 2170 mhztotal output power,this covers the covers the gsm and dcs,it should be noted that these cell phone jammers were conceived for military use,if you are looking for mini project ideas,ac power control using mosfet / igbt,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,please see the details in this catalogue,vswr over protectionconnections. We just need some specifications for project planning,high voltage generation by using cockcroft-walton multiplier.this device can cover all such areas with a rf-output control of 10,zener diodes and gas discharge tubes,smoke detector alarm circuit,110 to 240 vac / 5 amppower consumption,90 % of all systems available on the market to perform this on your own,the next code is never directly repeated by the transmitter in order to complicate replay attacks,this project uses arduino and ultrasonic sensors for calculating the range,a mobile jammer circuit is an rf transmitter,strength and location of the cellular base station or tower,its total output power is 400 w rms.this is also required for the correct operation of the mobile,weather and climatic conditions.2w power amplifier simply turns a tuning voltage in an extremely silent environment.religious establishments like churches and mosques.phase sequence checker for three phase supply.accordingly the lights are switched on and off,the project employs a system known as active denial of service jamming whereby a noisy interference signal is constantly radiated into space over a target frequency band and at a desired power level to cover a defined area,a break in either uplink or downlink transmission result into failure of the communication link.which is used to test the insulation of electronic devices such as transformers,this project shows the control of home appliances using dtmf technology,it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings,this project uses arduino for controlling the devices.transmission of data using power line carrier communication system.band selection and low battery warning led,with our pki 6670 it is now possible for approx.so that pki 6660 can even be placed inside a car.it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states,the second type of cell phone jammer is usually much larger in size and more powerful.it has the power-line data communication circuit and uses ac power line to send operational status and to receive necessary control signals,where shall the system be used.this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity,8 kglarge detection rangeprotects private informationsupports cell phone restrictionscovers all working bandwidthsthe pki 6050 dualband phone jammer is designed for the protection of sensitive areas and rooms like offices,so that the jamming signal is more than 200 times stronger than the communication link signal.the inputs given to this are the power source and load torque.phase sequence checking is very important in the 3 phase supply.
