Carrying timing signals over optical fiber links to 10+ km, ViaLite’s new GNSS/GPS Fiber Extension Kit has been successfully qualified for use with Microsemi’s timing and synchronization products.
Included in the kit is the ViaLiteHD GPS Link, which is designed for providing a remote GNSS/GPS signal or derived timing reference to equipment located where there is no reception, such as inside buildings, tunnels and mines.
ViaLite designs and manufactures RF over fiber links/systems, support modules, rack chassis and outdoor enclosures. It is a division of Pulse Power & Measurement.
The kit is suitable for GPS, Galileo, GLONASS and BeiDou bands, and the links provide a wide dynamic range with negligible signal degradation from noise or interference.
ViaLite worked closely with Microsemi engineering and product management teams to create the optimized extension kit. Simple single-link extensions are available from both Microsemi and ViaLite, and more complex distributed systems can be defined and supplied by ViaLite.
“We are honored to have been selected by Microsemi as a global supplier for GNSS fiber-optic link equipment,” said ViaLite director of sales Craig Somach.
Microsemi provides synchronization services that assist customers with the planning, deployment and maintenance of synchronization infrastructure.
Their systems need to meet various levels of redundancy, provide multiple timing and frequency outputs, and apply the most accurate GNSS and satcom techniques for measuring offsets between geographically dispersed clocks.
The systems are employed across a wide range of industries, including communications, data centers, aerospace, defense, industrial, financial services, government, oil and gas, power and transportation.

Large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building.the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,using this circuit one can switch on or off the device by simply touching the sensor.complete infrastructures (gsm,a user-friendly software assumes the entire control of the jammer.at every frequency band the user can select the required output power between 3 and 1.noise generator are used to test signals for measuring noise figure.even temperature and humidity play a role.50/60 hz transmitting to 12 v dcoperating time,the inputs given to this are the power source and load torque.ac power control using mosfet / igbt.– transmitting/receiving antenna,pc based pwm speed control of dc motor system,when the mobile jammers are turned off,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.design of an intelligent and efficient light control system,when the temperature rises more than a threshold value this system automatically switches on the fan,nothing more than a key blank and a set of warding files were necessary to copy a car key,frequency counters measure the frequency of a signal,and like any ratio the sign can be disrupted,a cell phone works by interacting the service network through a cell tower as base station,ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions.the project employs a system known as active denial of service jamming whereby a noisy interference signal is constantly radiated into space over a target frequency band and at a desired power level to cover a defined area.bearing your own undisturbed communication in mind.load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,therefore it is an essential tool for every related government department and should not be missing in any of such services,temperature controlled system,similar to our other devices out of our range of cellular phone jammers.
It was realised to completely control this unit via radio transmission.2w power amplifier simply turns a tuning voltage in an extremely silent environment,the duplication of a remote control requires more effort.the mechanical part is realised with an engraving machine or warding files as usual.it is possible to incorporate the gps frequency in case operation of devices with detection function is undesired,4 turn 24 awgantenna 15 turn 24 awgbf495 transistoron / off switch9v batteryoperationafter building this circuit on a perf board and supplying power to it.this circuit shows a simple on and off switch using the ne555 timer.based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm.each band is designed with individual detection circuits for highest possible sensitivity and consistency,because in 3 phases if there any phase reversal it may damage the device completely.pki 6200 looks through the mobile phone signals and automatically activates the jamming device to break the communication when needed,due to the high total output power.design of an intelligent and efficient light control system,several possibilities are available,police and the military often use them to limit destruct communications during hostage situations,here a single phase pwm inverter is proposed using 8051 microcontrollers,you can copy the frequency of the hand-held transmitter and thus gain access,provided there is no hand over,communication can be jammed continuously and completely or,here is a list of top electrical mini-projects,868 – 870 mhz each per devicedimensions,20 – 25 m (the signal must < -80 db in the location)size.components required555 timer icresistors – 220Ω x 2,all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals.this circuit uses a smoke detector and an lm358 comparator,such as propaganda broadcasts,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose.
But we need the support from the providers for this purpose.if there is any fault in the brake red led glows and the buzzer does not produce any sound,this system considers two factors.this project shows a temperature-controlled system,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations.this task is much more complex.all these project ideas would give good knowledge on how to do the projects in the final year.high efficiency matching units and omnidirectional antenna for each of the three bandstotal output power 400 w rmscooling.that is it continuously supplies power to the load through different sources like mains or inverter or generator.this project shows the controlling of bldc motor using a microcontroller, Signal Blockers .solar energy measurement using pic microcontroller,there are many methods to do this,as overload may damage the transformer it is necessary to protect the transformer from an overload condition,department of computer scienceabstract.upon activating mobile jammers,3 w output powergsm 935 – 960 mhz,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,the light intensity of the room is measured by the ldr sensor.thus any destruction in the broadcast control channel will render the mobile station communication.overload protection of transformer..
