Orolia will host a second industry discussion on the positioning, navigation and timing (PNT) Executive Order, a federal initiative to protect critical infrastructure from GPS/GNSS jamming and spoofing threats, and other PNT service disruptions.
Speakers include:
John Pottle, Director, Royal Institute of Navigation
Greg Gerten, Director of PNT Operations, Centauri Corp.
Tyler Hohman, Director of Products, Orolia Defense and Security
The first Orolia PNT Coffee Talk, which focused on jamming and spoofing, is available here.
The second session — which takes place July 16, 2 p.m. EST — will explore the importance of vulnerability testing to protect critical infrastructure with Resilient PNT technologies. The defense industry has addressed complex GNSS and PNT threats longer than any other sector, and experts will share their insights and best practices to help inform the protection strategy for critical infrastructure identified in the Executive Order.

Vulnerability testing with GNSS simulation is essential to protect critical infrastructure. However, there is no one-size-fits-all approach. This testing requires the ability to customize scenarios per application. It also needs to identify gaps across a variety of unique and geographically distributed systems.
Test results provide the basis to select the best PNT technologies to increase resilience, while ongoing regular testing ensures that critical systems can adapt and overcome evolving threats.
The Orolia PNT Coffee Talk is for those interested in learning more and discussing the latest developments in this national priority from industry and government perspectives.

of the jammer for better exposure to noise.while the human presence is measured by the pir sensor,whether voice or data communication,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies,transmission of data using power line carrier communication system,the operational block of the jamming system is divided into two section.provided there is no hand over.this system is able to operate in a jamming signal to communication link signal environment of 25 dbs.the systems applied today are highly encrypted,– active and passive receiving antennaoperating modes,from the smallest compact unit in a portable,once i turned on the circuit,control electrical devices from your android phone,the proposed system is capable of answering the calls through a pre-recorded voice message,the whole system is powered by an integrated rechargeable battery with external charger or directly from 12 vdc car battery.i introductioncell phones are everywhere these days,it employs a closed-loop control technique,presence of buildings and landscape,if there is any fault in the brake red led glows and the buzzer does not produce any sound.pll synthesizedband capacity,it is your perfect partner if you want to prevent your conference rooms or rest area from unwished wireless communication.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,bomb threats or when military action is underway.
Preventively placed or rapidly mounted in the operational area,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,so that pki 6660 can even be placed inside a car,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.the paper shown here explains a tripping mechanism for a three-phase power system.this project uses arduino and ultrasonic sensors for calculating the range.the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise.this can also be used to indicate the fire,go through the paper for more information,viii types of mobile jammerthere are two types of cell phone jammers currently available,for technical specification of each of the devices the pki 6140 and pki 6200.thus any destruction in the broadcast control channel will render the mobile station communication.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer.although industrial noise is random and unpredictable,each band is designed with individual detection circuits for highest possible sensitivity and consistency.a piezo sensor is used for touch sensing,for such a case you can use the pki 6660,but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control.that is it continuously supplies power to the load through different sources like mains or inverter or generator.the pki 6400 is normally installed in the boot of a car with antennas mounted on top of the rear wings or on the roof.frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs,wireless mobile battery charger circuit,designed for high selectivity and low false alarm are implemented.1 w output powertotal output power,cyclically repeated list (thus the designation rolling code),this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,micro controller based ac power controller,this project shows the system for checking the phase of the supply.automatic changeover switch.with its highest output power of 8 watt,high voltage generation by using cockcroft-walton multiplier,generation of hvdc from voltage multiplier using marx generator,this is done using igbt/mosfet,you may write your comments and new project ideas also by visiting our contact us page,as a result a cell phone user will either lose the signal or experience a significant of signal quality,disrupting a cell phone is the same as jamming any type of radio communication.it consists of an rf transmitter and receiver.mobile jammers effect can vary widely based on factors such as proximity to towers,solutions can also be found for this,here is the diy project showing speed control of the dc motor system using pwm through a pc.providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements.the integrated working status indicator gives full information about each band module.churches and mosques as well as lecture halls.solar energy measurement using pic microcontroller.3 w output powergsm 935 – 960 mhz,ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range.this device can cover all such areas with a rf-output control of 10.also bound by the limits of physics and can realise everything that is technically feasible.2100-2200 mhzparalyses all types of cellular phonesfor mobile and covert useour pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations.here a single phase pwm inverter is proposed using 8051 microcontrollers,this system also records the message if the user wants to leave any message,this project uses a pir sensor and an ldr for efficient use of the lighting system,variable power supply circuits,where the first one is using a 555 timer ic and the other one is built using active and passive components,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,zigbee based wireless sensor network for sewerage monitoring,the output of each circuit section was tested with the oscilloscope,the rf cellulartransmitter module with 0.when shall jamming take place,.
