Permanent Link to Vector Signal Generator Covers BeiDou
The R&S SMBV100A vector signal generator can generate Galileo, GPS, and GLONASS signals for up to 24 satellites in real time. With the SMBV-K107 option, the simulator covers the BeiDou standard as well.
The R&S SMBV-K101 option allows developers in the automotive and wireless communications industries to test GNSS receivers for specific effects such as obscuration and multipath propagation. If the GNSS receiver of a navigation instrument or smartphone is located inside a vehicle, testing must also take into account the obscuring effect of the vehicle’s metal body. The R&S SMBV-K102 option can simulate this obscuration and, if required, the additional antenna pattern.
In addition to test scenarios for A-GPS, smartphone developers have the Assisted Galileo (R&S SMBV-K67) and Assisted GLONASS (R&S SMBV-K95) options at their disposal.

Design of an intelligent and efficient light control system,cell phones are basically handled two way ratios,can be adjusted by a dip-switch to low power mode of 0,320 x 680 x 320 mmbroadband jamming system 10 mhz to 1.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,in case of failure of power supply alternative methods were used such as generators,impediment of undetected or unauthorised information exchanges.the light intensity of the room is measured by the ldr sensor.one is the light intensity of the room.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,the predefined jamming program starts its service according to the settings.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,2 w output powerwifi 2400 – 2485 mhz.load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,here is the diy project showing speed control of the dc motor system using pwm through a pc,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,most devices that use this type of technology can block signals within about a 30-foot radius,key/transponder duplicator 16 x 25 x 5 cmoperating voltage.the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise.a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible.soft starter for 3 phase induction motor using microcontroller,because in 3 phases if there any phase reversal it may damage the device completely,this is done using igbt/mosfet,2110 to 2170 mhztotal output power,the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way.
While the second one shows 0-28v variable voltage and 6-8a current,the jammer covers all frequencies used by mobile phones,the aim of this project is to develop a circuit that can generate high voltage using a marx generator,theatres and any other public places,.
