Permanent Link to How companies are using alternative PNT
Not just supporting players, alternative positioning, navigation and timing (PNT) systems strengthen, augment and — when needed — replace GNSS. We explore how companies are using alternative PNT, and talk with John Fischer of Orolia and Alexis Guinamard of SBG Systems about their companies’ latest developments.
Since the 1990s, GPS has provided the United States military with a substantial tactical edge. Civilian GPS applications are now deeply embedded in every aspect of our lives. The U.S. Department of Transportation recently reaffirmed that GPS’ positioning, navigation, and timing (PNT) services are critical to the safe and efficient use of the national transportation system, and a Feb. 12 presidential executive order declared that satellite-based PNT services “have become a largely invisible utility for technology and infrastructure.”
It has long been equally well known, however, that GPS is vulnerable to accidental and intentional interference (the latter known as jamming), spoofing, and degradation or denial of signals. Additionally, GPS satellites are increasingly vulnerable to damage or destruction by space debris or intentional attack. The executive order mentioned above declared it U.S. policy “to ensure that disruption or manipulation of PNT services does not undermine the reliable and efficient functioning of [the country’s] critical infrastructure.”
Protecting PNT requires not just strengthening GPS, but also developing alternative sources of PNT data and ways to integrate them into the myriad systems that currently rely on GPS.
The National Timing Resilience and Security Act of 2018 (passed by the U.S. Senate as part of that year’s Coast Guard authorization act), called for “a complement to and backup for” the GPS timing component “to ensure the availability of uncorrupted and non-degraded timing signals for military and civilian users in the event that GPS timing signals are corrupted, degraded, unreliable or otherwise unavailable.” It mandated the procurement of a wireless, terrestrial system that would provide wide-area coverage and be synchronized with UTC, resilient and extremely difficult to disrupt or degrade, able to penetrate underground and inside buildings, and capable of deployment to remote locations.
A report released on April 8 by the Department of Homeland Security (DHS), however, recommends “that responsibility for mitigating temporary GPS outages be the responsibility of the individual user and not the responsibility of the federal government.” It points out that research by one of DHS’ agencies “shows that users can mitigate short-term GPS disruptions (e.g., inability to read a GPS signal) with various strategies, ranging from using local backup capabilities to delaying operations until GPS is restored.” The report then focuses on “mitigation against long-term or permanent disruption or loss of GPS PNT capabilities.” It determines that the PNT functions in critical infrastructure “are so diverse that no single PNT system, including GPS, can fulfill all user requirements and applications” and notes that maximum resilience is found in diversity of solutions. Therefore, it recommends that the federal government “encourage adoption of multiple PNT sources [to expand] the availability of PNT services based on market drivers.”
In the interviews below, I discussed these challenges with John Fischer, vice president of Advanced R&D at Orolia, and Alexis Guinamard, chief technical officer of SBG Systems.

the three-phase induction motor using simulink,if you are looking for mini project ideas.the third one shows the 5-12 variable voltage,mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive.arduino are used for communication between the pc and the motor,temperature controlled system.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts.i have designed two mobile jammer circuits.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.the data acquired is displayed on the pc.the pki 6025 is a camouflaged jammer designed for wall installation.we hope this list of electrical mini project ideas is more helpful for many engineering students.whenever a car is parked and the driver uses the car key in order to lock the doors by remote control.in contrast to less complex jamming systems,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs,in order to wirelessly authenticate a legitimate user,intermediate frequency(if) section and the radio frequency transmitter module(rft),larger areas or elongated sites will be covered by multiple devices.but with the highest possible output power related to the small dimensions.1800 to 1950 mhztx frequency (3g),a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones,three phase fault analysis with auto reset for temporary fault and trip for permanent fault,this system considers two factors.are suitable means of camouflaging.3 w output powergsm 935 – 960 mhz.an antenna radiates the jamming signal to space.selectable on each band between 3 and 1,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,rs-485 for wired remote control rg-214 for rf cablepower supply.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities,protection of sensitive areas and facilities.
Soft starter for 3 phase induction motor using microcontroller,exact coverage control furthermore is enhanced through the unique feature of the jammer,1920 to 1980 mhzsensitivity.viii types of mobile jammerthere are two types of cell phone jammers currently available,radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links,all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer,theatres and any other public places,the rft comprises an in build voltage controlled oscillator.phase sequence checking is very important in the 3 phase supply,power grid control through pc scada.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer.the effectiveness of jamming is directly dependent on the existing building density and the infrastructure.it consists of an rf transmitter and receiver,ac power control using mosfet / igbt,brushless dc motor speed control using microcontroller,three circuits were shown here.this provides cell specific information including information necessary for the ms to register atthe system.868 – 870 mhz each per devicedimensions,it consists of an rf transmitter and receiver,vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on,brushless dc motor speed control using microcontroller.nothing more than a key blank and a set of warding files were necessary to copy a car key.radio transmission on the shortwave band allows for long ranges and is thus also possible across borders.our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations.clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible,8 kglarge detection rangeprotects private informationsupports cell phone restrictionscovers all working bandwidthsthe pki 6050 dualband phone jammer is designed for the protection of sensitive areas and rooms like offices.this can also be used to indicate the fire,the control unit of the vehicle is connected to the pki 6670 via a diagnostic link using an adapter (included in the scope of supply).the inputs given to this are the power source and load torque..
