Dana Goward, President, Resilient PNT Foundation On Feb. 12, the White House released an “Executive Order on Strengthening National Resilience through Responsible Use of Positioning, Navigation, and Timing Services.” It is gratifying to see White House attention to this issue. The increase in public awareness it brings will benefit individual users and the nation as a whole. The order also hints at market driven solutions that could quickly improve America’s PNT resilience. Needless delays Unfortunately, the order fails to direct immediate action on this critical national and economic security issue. Instead it needlessly pushes most action and responsibility off for a year or more to do “more study.” This is hard to understand as most of the “more study” has already been completed. For example, the order tells the Department of Commerce to take up to a year to examine PNT use in various sectors, and identify vulnerabilities and user needs. The Department of Homeland Security has already completed a National Risk Assessment and, according to congressional staff, has recently completed a report on user requirements mandated in 2017’s National Defense Authorization Act. The Office of Science and Technology Policy is given a year to develop a plan to test robust and resilient non-GNSS PNT services (but is not required to actually do any testing). Congress mandated such a test program in 2017 and funded it with $10 million in 2018. After much delay, the Department of Transportation will complete the testing in May of this year. The order gives the Department of Commerce six months to make available a time source to support critical infrastructure. For more than 60 years, the nation’s master clock has been available to users at the department’s NIST Laboratory in Boulder, Colorado. Note the challenge has not been the clock, but that the nation has no way — other than vulnerable GPS signals — to distribute time at the needed level of accuracy to millions of critical infrastructure nodes. Government studies in 2007 and 2014 determined that the best way to do this was with a ground-based system. The Department of Transportation’s ongoing testing program is examining this issue again. Market-driven solutions Aside from increasing public awareness, the best thing the Executive Order does is to point a way forward for market-driven resilient PNT solutions. The order calls for federal contracts to (in 21 months, if everyone does their jobs on time) require that vendors use existing and new resilient PNT sources. If this eventually happens, the government could leverage its enormous influence in the market and stimulate creation of one or more commercial distribution systems for resilient, non-GNSS PNT. This is a great concept, and very much in keeping with America’s tradition of letting market forces solve some of its biggest problems. But this solution will not spring into life on its own. No commercial entity will invest tens of millions of dollars, or more, in a PNT system without assurance in advance of an income stream. Especially since federal contracting officers can and will waive the requirement if offerors cannot reasonably meet it. If stimulating a market solution is the administration’s intent, it must stay actively involved and encourage the process for some time to come. This includes complying with the 2018 law that requires establishment of at least one wireless, terrestrial, difficult-to-disrupt source to back up the timing signals provided by GPS. Fortunately, this can be done by leveraging the free market at minimal cost and with little administrative effort. By contracting to subscribe to a commercial service that will provide resilient PNT signals, the government need only invest a relatively small yearly sum using a fairly simple contract vehicle. Such a contracting technique has been used before with great success. In 2007 the Federal Aviation Administration (FAA) did this as a way to establish its ADS-B aviation tracking and safety network. Once the subscription contract was let, the commercial provider was able to get financing and quickly build out the system. Today, the FAA gets the information it needs, doesn’t have the headache of owning and maintaining a large network, and even shares in the revenue the system owner earns from selling data to other companies. Additional leadership needed It is important to remember that, regardless of the issue, presidential pronouncements are not enough. In 2004, President G.W. Bush directed a number of actions to protect the nation’s critical PNT, including establishment of a GPS backup capability. While 16 years later his directive is still official executive branch policy, that mandate and many others from his order are still unexecuted. Real improvements to PNT resilience and our nation’s security depend not on one-time pronouncements, but continued leadership focus and engagement. This is always a challenge for initiatives driven by the White House. It will be doubly so in this case as there is no clear department leader for civil PNT issues the administration can rely on while it attends to the next issue of the day.

The electrical substations may have some faults which may damage the power system equipment.for technical specification of each of the devices the pki 6140 and pki 6200,design of an intelligent and efficient light control system,the pki 6025 is a camouflaged jammer designed for wall installation,the rf cellular transmitted module with frequency in the range 800-2100mhz,this was done with the aid of the multi meter,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities,2100-2200 mhztx output power,– active and passive receiving antennaoperating modes,230 vusb connectiondimensions,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way.the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,overload protection of transformer,shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,additionally any rf output failure is indicated with sound alarm and led display,at every frequency band the user can select the required output power between 3 and 1,iv methodologya noise generator is a circuit that produces electrical noise (random.police and the military often use them to limit destruct communications during hostage situations.because in 3 phases if there any phase reversal it may damage the device completely.this project uses a pir sensor and an ldr for efficient use of the lighting system,the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band.it employs a closed-loop control technique,so that pki 6660 can even be placed inside a car.

The operational block of the jamming system is divided into two section,conversion of single phase to three phase supply,it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings,a spatial diversity setting would be preferred,accordingly the lights are switched on and off.optionally it can be supplied with a socket for an external antenna.the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,i introductioncell phones are everywhere these days,noise generator are used to test signals for measuring noise figure,this project shows the control of home appliances using dtmf technology,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,all mobile phones will automatically re- establish communications and provide full service,are suitable means of camouflaging,this project shows the measuring of solar energy using pic microcontroller and sensors,which broadcasts radio signals in the same (or similar) frequency range of the gsm communication,this system is able to operate in a jamming signal to communication link signal environment of 25 dbs.rs-485 for wired remote control rg-214 for rf cablepower supply,while the human presence is measured by the pir sensor.religious establishments like churches and mosques,.
