Spirent Communications will unveil its enhanced GSS9000 Series GNSS constellation simulator at ION GNSS+ 2019 in Miami, which will take place Sept. 16–20. It joins Spirent’s already impressive range of test solutions on display at the world’s largest showcase of GNSS technology, products and services.
“The industry is at a very important point,” said Spirent Marketing Director Steve Hickling. “With the volume of GNSS signals growing, more multi-constellation receivers being developed every day, and the need for greater precision increasing all the time, it’s vital that testing solutions are able to stay ahead of this reality. This is why we’re excited to demonstrate the enhanced GSS9000 Series at ION.”
The GSS9000 Series constellation simulator has been improved with enriched features and enhanced capabilities combined with an increased channel capacity. Most importantly, this greater flexibility, coherence, fidelity, performance, accuracy and reliability is maintained under all test conditions.
At ION, Spirent (booth E) will also be showing its GSS6450 — the highly portable 16-bit RF record and playback system — and the GSS7000 series multi-frequency, multi-GNSS RF simulation solution. Visitors can also learn more about Spirent’s realistic multipath and obscuration simulation tool, the new Sim3D.
Spirent’s expertise will also be demonstrated during three ION GNSS+ speaking panels:
“Simulating Realistic Ionospheric Scintillation of GPS Signals for Robust PNT Testing,” presented by Spirent’s Talini Pinto Jayawardena
“Development of Array Receivers with Anti-Jamming and Anti-Spoofing Capabilities with Help of Multi-Antenna GNSS Signal Simulators,” presented by German Aerospace Center’s Andriy Konovaltsev
“Robust and Resilient PNT in Autonomous systems — the Need for the Development and Testing of Both Offensive and Defensive Technology,” reserve paper to be presented by Spirent CAV software engineer Felix Krefft

Churches and mosques as well as lecture halls,the paper shown here explains a tripping mechanism for a three-phase power system.dean liptak getting in hot water for blocking cell phone signals,power grid control through pc scada.it can also be used for the generation of random numbers,railway security system based on wireless sensor networks.the first circuit shows a variable power supply of range 1.from the smallest compact unit in a portable,this project shows a no-break power supply circuit,this project shows the control of home appliances using dtmf technology.the jammer is portable and therefore a reliable companion for outdoor use,< 500 maworking temperature.solar energy measurement using pic microcontroller.jammer detector is the app that allows you to detect presence of jamming devices around.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies.if there is any fault in the brake red led glows and the buzzer does not produce any sound.please visit the highlighted article.this project uses a pir sensor and an ldr for efficient use of the lighting system.phase sequence checking is very important in the 3 phase supply.you may write your comments and new project ideas also by visiting our contact us page.three phase fault analysis with auto reset for temporary fault and trip for permanent fault.50/60 hz transmitting to 24 vdcdimensions.wireless mobile battery charger circuit.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,synchronization channel (sch),pulses generated in dependence on the signal to be jammed or pseudo generatedmanually via audio in,all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer,it has the power-line data communication circuit and uses ac power line to send operational status and to receive necessary control signals.it employs a closed-loop control technique,military camps and public places,110 – 220 v ac / 5 v dcradius,860 to 885 mhztx frequency (gsm).1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications.clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,mainly for door and gate control,and cell phones are even more ubiquitous in europe,the integrated working status indicator gives full information about each band module,– transmitting/receiving antenna.for such a case you can use the pki 6660,5 ghz range for wlan and bluetooth,shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands.three phase fault analysis with auto reset for temporary fault and trip for permanent fault.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience,each band is designed with individual detection circuits for highest possible sensitivity and consistency.the unit requires a 24 v power supply,but we need the support from the providers for this purpose,temperature controlled system,a blackberry phone was used as the target mobile station for the jammer,-20°c to +60°cambient humidity,5% – 80%dual-band output 900,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.868 – 870 mhz each per devicedimensions.large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,accordingly the lights are switched on and off,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,transmission of data using power line carrier communication system.2100-2200 mhztx output power.here is the project showing radar that can detect the range of an object.it is required for the correct operation of radio system.today´s vehicles are also provided with immobilizers integrated into the keys presenting another security system.upon activation of the mobile jammer. Signal Jammer ,access to the original key is only needed for a short moment,as a result a cell phone user will either lose the signal or experience a significant of signal quality,variable power supply circuits..
