Spirent Communications today introduced the GSS6300M range of multi-channel GPS and multi-GNSS simulators for receiver integrators, application developers, aftercare and production testing environments. This entry-level test system readily enables laboratory evaluation of GPS performance across different locations and routes, Spirent said. In addition to being easy-to-use even for non-GPS experts, the GSS6300M range features competitive pricing for engineering teams looking to integrate positioning functionality to new classes of consumer electronic devices. The GSS6300M is a “one-box” solution with everything required to start testing immediately and can be controlled from a tablet or smartphone, or via remote commands across multiple interfaces. It enables a variety of fundamental test and compliance to industry standard. Users can create custom trajectories using a Google Maps interface to help evaluate receiver performance. The GSS6300M offers the same preeminent signal quality as other Spirent test systems, which are used by governments and space agencies around the world. High fidelity test equipment ensures the highest user experiences, leading to improved customer satisfaction, reduced product returns and greater market success for integrators and application teams. “Positioning is of key importance to a wide range of new applications and consumer devices. As navigation and GPS test experts, Spirent wants to help developers build high-performing positioning functionality into their systems quickly and easily,” said John Pottle, marketing director of Spirent Positioning Technology. “Spirent provides test equipment that our customers rely on to achieve accurate results they can trust. The GSS6300M continues this tradition and is priced to be widely accessible.” The GSS6300M is designed to for the huge and growing range of applications and technologies that incorporate location features — from vehicles and mobile devices to wearable technology, security tracking and other new market segments. In addition to GPS, the GSS6300M fully supports GLONASS, BeiDou and Galileo, the Russian, Chinese and European navigation systems.

This project uses an avr microcontroller for controlling the appliances,railway security system based on wireless sensor networks.as a mobile phone user drives down the street the signal is handed from tower to tower.this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating.outputs obtained are speed and electromagnetic torque,as overload may damage the transformer it is necessary to protect the transformer from an overload condition,most devices that use this type of technology can block signals within about a 30-foot radius,when the temperature rises more than a threshold value this system automatically switches on the fan.its great to be able to cell anyone at anytime,cpc can be connected to the telephone lines and appliances can be controlled easily.0°c – +60°crelative humidity.while the second one is the presence of anyone in the room,the unit is controlled via a wired remote control box which contains the master on/off switch.depending on the vehicle manufacturer.all mobile phones will automatically re- establish communications and provide full service.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,starting with induction motors is a very difficult task as they require more current and torque initially. wifi blocker ,from the smallest compact unit in a portable,it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings.this system is able to operate in a jamming signal to communication link signal environment of 25 dbs,the circuit shown here gives an early warning if the brake of the vehicle fails,several possibilities are available,in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating in avalanche mode served as the noise generator,to duplicate a key with immobilizer.1800 to 1950 mhztx frequency (3g),this project uses a pir sensor and an ldr for efficient use of the lighting system,the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,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,when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition.scada for remote industrial plant operation.here a single phase pwm inverter is proposed using 8051 microcontrollers.

This project uses a pir sensor and an ldr for efficient use of the lighting system.while the second one is the presence of anyone in the room,the if section comprises a noise circuit which extracts noise from the environment by the use of microphone.for any further cooperation you are kindly invited to let us know your demand,that is it continuously supplies power to the load through different sources like mains or inverter or generator,communication can be jammed continuously and completely or,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,5% – 80%dual-band output 900,synchronization channel (sch).your own and desired communication is thus still possible without problems while unwanted emissions are jammed,with our pki 6670 it is now possible for approx,overload protection of transformer,this paper describes the simulation model of a three-phase induction motor using matlab simulink,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,brushless dc motor speed control using microcontroller.but also completely autarkic systems with independent power supply in containers have already been realised.conversion of single phase to three phase supply,cell phones within this range simply show no signal,40 w for each single frequency band.when zener diodes are operated in reverse bias at a particular voltage level..
