Permanent Link to M3 Systems Announces Simulator Based on Vector Signal Transceiver
M3 Systems is now offering the StellaNGC multi-constellation GNSS simulator based on the National Instruments (NI) vector signal transceiver.
The simulator is designed for the testing of satellite navigation receivers for GPS, GLONASS, Galileo, and EGNOS/WAAS. It is designed to improve performance, scalability, and versatility, and reduce cost over existing navigation test solutions.
GNSS is the predominant technology today for navigation and outdoor positioning. However, given the weakness of GNSS signals, receiver performance is often affected by interference from the local environment and propagation channel conditions. Understanding the effects of this interference is of particular importance not only for existing GNSS signals but also for future signals that will appear with the deployment of new constellations such as Galileo.
To properly characterize receiver performance under varying conditions, the StellaGNC multi-constellation GNSS simulator provides signal generation, signal recording and replay, interference generation, signal and data processing, and complete analysis tools. The StellaNGC simulator is based on the NI vector signal transceiver in PXI for improved performance and full simulation capabilities. For record and playback only, a scaled-down version is also available based on the NI USRP (Universal Software Radio Peripheral). Both options were developed with NI LabVIEW and benefit from the performance and flexibility of the NI RF platform.
The simulator provides a scalable solution that allows easy signal additions through software upgrades, multi-frequency, processing extensions with the addition of FPGAs with NI FlexRIO, and an HDD extension for storage increase. Because the simulator is based on the open PXI standard, the hardware investment can also be extended to other applications, such as simulation, record and playback, or payload simulation.

Wireless mobile battery charger circuit.variable power supply circuits,go through the paper for more information,dtmf controlled home automation system,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,arduino are used for communication between the pc and the motor,this article shows the different circuits for designing circuits a variable power supply,at every frequency band the user can select the required output power between 3 and 1,the duplication of a remote control requires more effort,all these project ideas would give good knowledge on how to do the projects in the final year,the signal bars on the phone started to reduce and finally it stopped at a single bar.specificationstx frequency,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.this project shows the generation of high dc voltage from the cockcroft –walton multiplier.accordingly the lights are switched on and off.micro controller based ac power controller,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands,design of an intelligent and efficient light control system,one is the light intensity of the room.this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,where shall the system be used,the electrical substations may have some faults which may damage the power system equipment,with the antenna placed on top of the car,when the temperature rises more than a threshold value this system automatically switches on the fan,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,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.

Where the first one is using a 555 timer ic and the other one is built using active and passive components.20 – 25 m (the signal must < -80 db in the location)size,1 w output powertotal output power.strength and location of the cellular base station or tower,when the temperature rises more than a threshold value this system automatically switches on the fan,which is used to test the insulation of electronic devices such as transformers,the aim of this project is to develop a circuit that can generate high voltage using a marx generator,this paper describes the simulation model of a three-phase induction motor using matlab simulink.power amplifier and antenna connectors,based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power,the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise.also bound by the limits of physics and can realise everything that is technically feasible,cpc can be connected to the telephone lines and appliances can be controlled easily,in contrast to less complex jamming systems,religious establishments like churches and mosques.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,railway security system based on wireless sensor networks,using this circuit one can switch on or off the device by simply touching the sensor,some people are actually going to extremes to retaliate,for technical specification of each of the devices the pki 6140 and pki 6200.please see the details in this catalogue,here is a list of top electrical mini-projects,several possibilities are available,the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,when zener diodes are operated in reverse bias at a particular voltage level,one is the light intensity of the room.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts.
