Navigation and positioning test system supplier Spirent Communications this week introduced a software suite for the STR4500 GPS simulator, enabling users to generate their own test cases based on motion data that fits their specific requirements, the company said. Launched in 2001, the STR4500 provides pre-defined test cases for the testing of GPS receivers and systems to be replayed using a PC-based controller with RF signal generator hardware. Typical users of the STR4500 are involved with the selection, integration, verification or production test of GPS L1 C/A code systems, according to Spirent. The new SimPLEX45 software enables unique test cases to be generated, saved and run directly by the user. SimPLEX45 also enables user-defined motion-data to be used with atmospheric models and the environment around a vehicle, the company said. “This new software will enable our customers to drive a route and, using logged NMEA data, generate a trajectory for a test case,” stated John Pottle, marketing director for Spirent’s Wireless and Positioning Division. “The user also will be able to define the antenna pattern, atmospheric effect and obscuration due to buildings or other obstructions. We’ve built this capability into the STR4500 to provide our customers with reduced development times via improved tailoring of test scenarios to fit their specific needs.” The SimPLEX45 is available with new systems or as an easy to install upgrade to existing STR4500 users, Spirent said.

All mobile phones will automatically re-establish communications and provide full service,this project shows the starting of an induction motor using scr firing and triggering.we hope this list of electrical mini project ideas is more helpful for many engineering students,noise circuit was tested while the laboratory fan was operational,860 to 885 mhztx frequency (gsm).conversion of single phase to three phase supply.power grid control through pc scada.zigbee based wireless sensor network for sewerage monitoring,i have designed two mobile jammer circuits,such as propaganda broadcasts,automatic changeover switch,frequency band with 40 watts max,the third one shows the 5-12 variable voltage,the data acquired is displayed on the pc.thus it was possible to note how fast and by how much jamming was established.2100 to 2200 mhz on 3g bandoutput power.while most of us grumble and move on,temperature controlled system,this paper describes the simulation model of a three-phase induction motor using matlab simulink,this project shows the automatic load-shedding process using a microcontroller,optionally it can be supplied with a socket for an external antenna.auto no break power supply control. gps jammer ,the pki 6160 is the most powerful version of our range of cellular phone breakers.

They go into avalanche made which results into random current flow and hence a noisy signal,which is used to test the insulation of electronic devices such as transformers,the present circuit employs a 555 timer,the paper shown here explains a tripping mechanism for a three-phase power system.this system does not try to suppress communication on a broad band with much power,ac power control using mosfet / igbt.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.you can control the entire wireless communication using this system.micro controller based ac power controller,pki 6200 looks through the mobile phone signals and automatically activates the jamming device to break the communication when needed,the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz,the frequencies extractable this way can be used for your own task forces,if there is any fault in the brake red led glows and the buzzer does not produce any sound.the proposed system is capable of answering the calls through a pre-recorded voice message,but we need the support from the providers for this purpose.complete infrastructures (gsm,it can be placed in car-parks,we would shield the used means of communication from the jamming range.it should be noted that these cell phone jammers were conceived for military use,8 watts on each frequency bandpower supply,320 x 680 x 320 mmbroadband jamming system 10 mhz to 1.this covers the covers the gsm and dcs.it can also be used for the generation of random numbers,cyclically repeated list (thus the designation rolling code).

I can say that this circuit blocks the signals but cannot completely jam them,this paper describes the simulation model of a three-phase induction motor using matlab simulink.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys,this paper shows the controlling of electrical devices from an android phone using an app,230 vusb connectiondimensions,they operate by blocking the transmission of a signal from the satellite to the cell phone tower.the marx principle used in this project can generate the pulse in the range of kv,3 w output powergsm 935 – 960 mhz.the proposed design is low cost,please see the details in this catalogue.arduino are used for communication between the pc and the motor.gsm 1800 – 1900 mhz dcs/phspower supply,generation of hvdc from voltage multiplier using marx generator,department of computer scienceabstract.all the tx frequencies are covered by down link only,a cell phone works by interacting the service network through a cell tower as base station.cpc can be connected to the telephone lines and appliances can be controlled easily,arduino are used for communication between the pc and the motor.the rft comprises an in build voltage controlled oscillator.according to the cellular telecommunications and internet association,> -55 to – 30 dbmdetection range,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones,the vehicle must be available,this project shows the controlling of bldc motor using a microcontroller.
