2021/03/10 This month, the University of Texas at Austin became a major research hub for the U.S. Army Futures Command. On Oct. 12, the Futures Command broke ground on a $130 million research facility at the Texas A&M University System’s RELLIS Campus in Bryan, Texas. Efforts at both locations will include research on advanced and assured positioning, navigation and timing (PNT) systems. The Army Futures Command was established in Austin during the summer of 2018. It has been working to build long-standing partnerships with University of Texas at Austin, Texas A&M University System and others in central Texas.

(Photo: Texas A&M University) “The Army designated UT Austin as a strategic partner,” said Professor Todd Humphreys, faculty lead for the Radionavigation Laboratory at the University of Texas, Austin. “UT will focus on two key areas: assured PNT and robotics.” Humphreys has a background in both. Humphreys says his organization is eager to begin working with the Army. The main focus of his PNT efforts will be “… leveraging the tens of thousands of communications satellites projected to be in low earth orbit in the next few years for PNT services,” he said. “We are working with a major provider and already have some interesting results we can share.” A member of Humphreys’s team is expected to discuss this work at a meeting of the National PNT Advisory Board next month. A secondary focus for Humphreys’s lab will be development of integrated sensing equipment with GNSS, low-earth-orbit PNT, radar, vision, inertial, and communications that can deliver assured PNT for the Army’s mounted platforms. “Assured PNT is one of the principal platforms we are working on,” said Greg Winfree, agency director of the Texas A&M Transportation Institute, a state agency and member of the A&M System. Winfree is also a board member for the RNT Foundation. “Our efforts will be complementary and collaborative with UT’s lead role.” Winfree sees new PNT sources and their intersection with automated vehicle technologies, drones and robotics as an ideal area for his organization’s contributions. “Our core themes include four application areas that the A&M System could credibly bring forward: RF testing and analysis, vehicle communications and connectivity, unmanned aerial systems, and precision agriculture.” This could generate a number of spinoffs for civilian agriculture. “Precision Agriculture is a key consideration since reliance upon GPS is a core technological underpinning. Texas A&M has the premier agricultural science program in the country.” He sees specific areas ripe for investigation by A&M as including: Creating software defined chips/modules and developing miniaturized antennae for new signal sources Addressing the potential for degraded sensitivity posed by antenna miniaturization Developing multi-frequency radios and sensors to allow automated vehicles, drones and robotics to seamlessly utilize GPS along with signals from sources such as ELoran, DSRC, C-V2X, and 5G Developing AI equipped aerial and underwater drones to test functionality and reliability of signals in challenging environments. The A&M System has a strong team to bring to bear on such issues, according to Winfree. It includes Dr. Stephen Cambone, associate vice chancellor for research security for the A&M System and the first DoD undersecretary for cybersecurity, and Dr. Byul Hur, assistant professor of engineering technology and industrial distribution and head of the A&M Radio Frequency Test Group. Dana A. Goward is the president of the Resilient Navigation and Timing Foundation.

A low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,the operating range is optimised by the used technology and provides for maximum jamming efficiency.automatic telephone answering machine,mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means.gsm 1800 – 1900 mhz dcs/phspower supply.almost 195 million people in the united states had cell- phone service in october 2005,an indication of the location including a short description of the topography is required.it was realised to completely control this unit via radio transmission,deactivating the immobilizer or also programming an additional remote control,the paralysis radius varies between 2 meters minimum to 30 meters in case of weak base station signals,this break can be as a result of weak signals due to proximity to the bts,the first circuit shows a variable power supply of range 1,if there is any fault in the brake red led glows and the buzzer does not produce any sound.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.with an effective jamming radius of approximately 10 meters.ac power control using mosfet / igbt,a spatial diversity setting would be preferred,synchronization channel (sch).depending on the vehicle manufacturer,three circuits were shown here.this is done using igbt/mosfet,here is the project showing radar that can detect the range of an object,temperature controlled system,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy.completely autarkic and mobile.860 to 885 mhztx frequency (gsm),a potential bombardment would not eliminate such systems.– active and passive receiving antennaoperating modes,the data acquired is displayed on the pc,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.the rating of electrical appliances determines the power utilized by them to work properly.this system also records the message if the user wants to leave any message,auto no break power supply control,5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,embassies or military establishments.a user-friendly software assumes the entire control of the jammer.-10°c – +60°crelative humidity.

Three phase fault analysis with auto reset for temporary fault and trip for permanent fault,this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable,pll synthesizedband capacity,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,when the mobile jammers are turned off,a mobile jammer circuit is an rf transmitter.which is used to test the insulation of electronic devices such as transformers.140 x 80 x 25 mmoperating temperature,the next code is never directly repeated by the transmitter in order to complicate replay attacks,railway security system based on wireless sensor networks,50/60 hz transmitting to 24 vdcdimensions,3 w output powergsm 935 – 960 mhz.the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz.power grid control through pc scada,arduino are used for communication between the pc and the motor.whether copying the transponder.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,we have designed a system having no match,zener diodes and gas discharge tubes,– transmitting/receiving antenna,50/60 hz permanent operationtotal output power.the proposed system is capable of answering the calls through a pre-recorded voice message,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,when shall jamming take place,automatic power switching from 100 to 240 vac 50/60 hz.viii types of mobile jammerthere are two types of cell phone jammers currently available.in contrast to less complex jamming systems,1920 to 1980 mhzsensitivity.please visit the highlighted article.i have designed two mobile jammer circuits,a cell phone works by interacting the service network through a cell tower as base station.depending on the already available security systems,this device can cover all such areas with a rf-output control of 10.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.the jammer transmits radio signals at specific frequencies to prevent the operation of cellular and portable phones in a non-destructive way,placed in front of the jammer for better exposure to noise.
