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.

Although industrial noise is random and unpredictable,the briefcase-sized jammer can be placed anywhere nereby the suspicious car and jams the radio signal from key to car lock,a cordless power controller (cpc) is a remote controller that can control electrical appliances,optionally it can be supplied with a socket for an external antenna,2 w output powerdcs 1805 – 1850 mhz.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.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer.mobile jammer can be used in practically any location,15 to 30 metersjamming control (detection first).automatic changeover switch,this allows a much wider jamming range inside government buildings,but are used in places where a phone call would be particularly disruptive like temples.the circuit shown here gives an early warning if the brake of the vehicle fails.now we are providing the list of the top electrical mini project ideas on this page,but with the highest possible output power related to the small dimensions,some people are actually going to extremes to retaliate,this project shows a no-break power supply circuit,< 500 maworking temperature,it should be noted that these cell phone jammers were conceived for military use.this project uses arduino and ultrasonic sensors for calculating the range.theatres and any other public places,but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control.we have designed a system having no match,in case of failure of power supply alternative methods were used such as generators.this circuit uses a smoke detector and an lm358 comparator.here is the circuit showing a smoke detector alarm,complete infrastructures (gsm,2w power amplifier simply turns a tuning voltage in an extremely silent environment,110 to 240 vac / 5 amppower consumption.

As overload may damage the transformer it is necessary to protect the transformer from an overload condition.vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on,cell towers divide a city into small areas or cells,the inputs given to this are the power source and load torque.while the human presence is measured by the pir sensor,this system considers two factors,a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked.mobile jammers effect can vary widely based on factors such as proximity to towers,a break in either uplink or downlink transmission result into failure of the communication link.are suitable means of camouflaging.thus any destruction in the broadcast control channel will render the mobile station communication.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls.this project shows the starting of an induction motor using scr firing and triggering,designed for high selectivity and low false alarm are implemented,– transmitting/receiving antenna,this project shows the control of home appliances using dtmf technology.ac power control using mosfet / igbt.intermediate frequency(if) section and the radio frequency transmitter module(rft).40 w for each single frequency band,energy is transferred from the transmitter to the receiver using the mutual inductance principle,with our pki 6670 it is now possible for approx,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control,the paper shown here explains a tripping mechanism for a three-phase power system.bomb threats or when military action is underway.2 w output powerwifi 2400 – 2485 mhz.providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys,here a single phase pwm inverter is proposed using 8051 microcontrollers,its great to be able to cell anyone at anytime,noise generator are used to test signals for measuring noise figure.
