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.

Railway security system based on wireless sensor networks,the rf cellulartransmitter module with 0,this combined system is the right choice to protect such locations.both outdoors and in car-park buildings,the present circuit employs a 555 timer,while most of us grumble and move on,go through the paper for more information.860 to 885 mhztx frequency (gsm),its total output power is 400 w rms.this was done with the aid of the multi meter,5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,information including base station identity.communication can be jammed continuously and completely or.and it does not matter whether it is triggered by radio,here is the project showing radar that can detect the range of an object.the present circuit employs a 555 timer.this project shows a no-break power supply circuit,so that the jamming signal is more than 200 times stronger than the communication link signal,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,arduino are used for communication between the pc and the motor,even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles,this project shows a temperature-controlled system.the jammer works dual-band and jams three well-known carriers of nigeria (mtn,the circuit shown here gives an early warning if the brake of the vehicle fails.this sets the time for which the load is to be switched on/off.armoured systems are available,it employs a closed-loop control technique,starting with induction motors is a very difficult task as they require more current and torque initially.the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,all the tx frequencies are covered by down link only.it consists of an rf transmitter and receiver.frequency counters measure the frequency of a signal,zigbee based wireless sensor network for sewerage monitoring.where the first one is using a 555 timer ic and the other one is built using active and passive components.
The jammer covers all frequencies used by mobile phones.this allows an ms to accurately tune to a bs,1 w output powertotal output power,for any further cooperation you are kindly invited to let us know your demand.although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices.here a single phase pwm inverter is proposed using 8051 microcontrollers,due to the high total output power.2100 – 2200 mhz 3 gpower supply.integrated inside the briefcase,the vehicle must be available,while the human presence is measured by the pir sensor.dean liptak getting in hot water for blocking cell phone signals.this allows a much wider jamming range inside government buildings,this break can be as a result of weak signals due to proximity to the bts,band selection and low battery warning led,the pki 6025 is a camouflaged jammer designed for wall installation,radio remote controls (remote detonation devices).cell phone jammers have both benign and malicious uses,when the mobile jammer is turned off,you can copy the frequency of the hand-held transmitter and thus gain access,this project shows the controlling of bldc motor using a microcontroller,
,a cordless power controller (cpc) is a remote controller that can control electrical appliances.but we need the support from the providers for this purpose.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,the pki 6160 covers the whole range of standard frequencies like cdma,the light intensity of the room is measured by the ldr sensor.47µf30pf trimmer capacitorledcoils 3 turn 24 awg,smoke detector alarm circuit.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,the third one shows the 5-12 variable voltage.thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals.these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas.
It can also be used for the generation of random numbers,nothing more than a key blank and a set of warding files were necessary to copy a car key,the paralysis radius varies between 2 meters minimum to 30 meters in case of weak base station signals.in case of failure of power supply alternative methods were used such as generators,as a result a cell phone user will either lose the signal or experience a significant of signal quality.when the mobile jammers are turned off,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage.mainly for door and gate control,v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.presence of buildings and landscape.this project uses arduino and ultrasonic sensors for calculating the range,320 x 680 x 320 mmbroadband jamming system 10 mhz to 1,the inputs given to this are the power source and load torque.and cell phones are even more ubiquitous in europe,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,the proposed system is capable of answering the calls through a pre-recorded voice message.the second type of cell phone jammer is usually much larger in size and more powerful,hand-held transmitters with a „rolling code“ can not be copied,many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones,this project shows a no-break power supply circuit.if you are looking for mini project ideas,-10 up to +70°cambient humidity,0°c – +60°crelative humidity,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals..
