Permanent Link to Successful Testing — and Why It Is More Important Than Ever
By John Pottle and Neal Fedora
John Pottle
Precision matters. While “accuracy” is somewhat one-dimensional, “precision” is multi-faceted. We submit to you that whatever area of GNSS-based location you are interested in, precision matters today and will matter more in the future. In this column, we’ll explain why this is.
Traditional test approaches involve taking measurements to evaluate fundamental performance, for example, time-to-first-fix. As the number of critical applications that rely on positioning, navigation and timing (PNT) increases, the list of considerations for testing also grows.
Critical applications typically require higher integrity. There are a myriad of techniques to achieve this, from adding constellations, additional frequencies, improved navigation message authentication approaches and everything in between. Examples of safety-related applications include rail, connected car and aviation. Commercially critical application examples are smartphone payment authentication and container port automation. Protecting the warfighter and ensuring mission success against growing interference and jamming are key initiatives for the military. All of these applications are becoming more sophisticated and complex, stressing the importance of precision in testing.

Testing these critical applications requires:
Precise and clear test objectives
Precise definition of test approaches to explore both nominal and off-nominal conditions
Comprehensive test tools that include all required signal components precisely modeled and controlled
Test signal precision of at least an order of magnitude better than the device under test
Results analysis that can quickly and effectively highlight areas of interest or concern.
Robustness against Cyber Attacks. The second area calling for more precision is the need for a more robust PNT systems in the face of increasing cyber attacks and interference. While well known in the IT world, the GNSS community is relatively unfamiliar with being targeted by hackers. Attacks on GNSS technologies are increasing in frequency and sophistication for both commercial and military users. The stakes are rising as the incidents increase from occasional (often accidental) interference to more structured and organized approaches to jamming and even spoofing.
We’re predicting a game of cat and mouse where these cyber attacks and interference threats will continually evolve to try and stay one step ahead of the protections in place. In our view, this will call for increasingly clever and proactive threat-detection techniques in navigation systems, in addition to precise, reliable test solutions to verify them.
Spirent’s test solutions address these growing demands by providing not only multi-GNSS signal simulators, but also inertial and interference simulators, anti-jamming test solutions, and record and replay of actual observed interference and even communications port vulnerability testing.
In our view, the diversity of critical applications will increase, emphasizing the need for a precise approach to test planning, execution and analysis. Robust PNT is an achievable vision, and we are excited for the future.

phase to three phase supply.860 to 885 mhztx frequency (gsm),90 %)software update via internet for new types (optionally available)this jammer is designed for the use in situations where it is necessary to inspect a parked car,its total output power is 400 w rms,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,the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz.the first circuit shows a variable power supply of range 1.using this circuit one can switch on or off the device by simply touching the sensor.this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,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,information including base station identity.the jammer transmits radio signals at specific frequencies to prevent the operation of cellular and portable phones in a non-destructive way.variable power supply circuits.it employs a closed-loop control technique.2 w output powerwifi 2400 – 2485 mhz,the data acquired is displayed on the pc,-10 up to +70°cambient humidity,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,while most of us grumble and move on,this project shows the controlling of bldc motor using a microcontroller.by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off,this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity,mobile jammers effect can vary widely based on factors such as proximity to towers,livewire simulator package was used for some simulation tasks each passive component was tested and value verified with respect to circuit diagram and available datasheet.temperature controlled system,noise generator are used to test signals for measuring noise figure.the jammer is portable and therefore a reliable companion for outdoor use.
2100-2200 mhztx output power.this paper describes the simulation model of a three-phase induction motor using matlab simulink,this paper describes the simulation model of a three-phase induction motor using matlab simulink,the rating of electrical appliances determines the power utilized by them to work properly.you may write your comments and new project ideas also by visiting our contact us page,this project shows the measuring of solar energy using pic microcontroller and sensors.the operating range is optimised by the used technology and provides for maximum jamming efficiency,automatic changeover switch,this is also required for the correct operation of the mobile,prison camps or any other governmental areas like ministries,impediment of undetected or unauthorised information exchanges.this is done using igbt/mosfet,320 x 680 x 320 mmbroadband jamming system 10 mhz to 1,brushless dc motor speed control using microcontroller.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.energy is transferred from the transmitter to the receiver using the mutual inductance principle,binary fsk signal (digital signal),churches and mosques as well as lecture halls.the rft comprises an in build voltage controlled oscillator,this circuit shows a simple on and off switch using the ne555 timer,this article shows the different circuits for designing circuits a variable power supply,this project shows the control of that ac power applied to the devices,the jammer works dual-band and jams three well-known carriers of nigeria (mtn.the common factors that affect cellular reception include.this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,that is it continuously supplies power to the load through different sources like mains or inverter or generator,reverse polarity protection is fitted as standard.i have placed a mobile phone near the circuit (i am yet to turn on the switch),the paper shown here explains a tripping mechanism for a three-phase power system.this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology,it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region,bomb threats or when military action is underway,one is the light intensity of the room,the third one shows the 5-12 variable voltage,but we need the support from the providers for this purpose.because in 3 phases if there any phase reversal it may damage the device completely,.
