Luch-5B, the second of a set of three geostationary satellites being launched to reactivate Roscosmos’s Luch Multifunctional Space Relay System, has been delivered to the Baikonur Cosmodrome. It arrived together with the Yamal-300K satellite in a single shipping container aboard an Antanov An-124-100 Ruslan flight from Krasnoyarsk.
This marked the first time that Information Satellite Systems – Reshetnev has used the special container, which is large enough to carry two middle-class spacecraft at one time. According to the company, sophisticated equipment fitted with a control system that helps monitor the environment inside the container helps avoid any chances of external damage or unwanted environmental impact during transportation.
Luch-5B is now undergoing preparations for launch.
The Luch system will be used to relay communications and telemetry between low-Earth-orbiting spacecraft, such as the the Russian segment of International Space Station, and Russian ground facilities.
The system’s satellites also carry transponders for the System for Differential Correction and Monitoring (SDCM), Russia’s satellite-based augmentation system. The transponders will broadcast GNSS corrections on the standard GPS L1 frequency using C/A PRN codes assigned by DoD’s Global Positioning Systems Directorate.
As previously reported, Luch-5A, which was launched on 11 December 2011, has been placed in an orbital slot at 95 degrees east longitude. It began transmitting corrections on July 12, 2012, using PRN code 140.
Luch-5B, scheduled for launch on September 7, 2012, will be positioned at 16 degrees west longitude.

Go through the paper for more information.this project uses arduino for controlling the devices.here is a list of top electrical mini-projects.phase sequence checking is very important in the 3 phase supply.the circuit shown here gives an early warning if the brake of the vehicle fails,selectable on each band between 3 and 1.here is the project showing radar that can detect the range of an object,please visit the highlighted article,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating.this article shows the different circuits for designing circuits a variable power supply,an antenna radiates the jamming signal to space,here is the circuit showing a smoke detector alarm.2 to 30v with 1 ampere of current,disrupting a cell phone is the same as jamming any type of radio communication,both outdoors and in car-park buildings,this paper describes the simulation model of a three-phase induction motor using matlab simulink,overload protection of transformer.this combined system is the right choice to protect such locations.the rft comprises an in build voltage controlled oscillator,here is a list of top electrical mini-projects,90 %)software update via internet for new types (optionally available)this jammer is designed for the use in situations where it is necessary to inspect a parked car.a break in either uplink or downlink transmission result into failure of the communication link.when the mobile jammer is turned off,brushless dc motor speed control using microcontroller,40 w for each single frequency band.frequency counters measure the frequency of a signal,this provides cell specific information including information necessary for the ms to register atthe system.

The unit requires a 24 v power supply,it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states.2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies,this is also required for the correct operation of the mobile.the jammer covers all frequencies used by mobile phones.a user-friendly software assumes the entire control of the jammer,this is done using igbt/mosfet.designed for high selectivity and low false alarm are implemented.the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device.at every frequency band the user can select the required output power between 3 and 1,the complete system is integrated in a standard briefcase,and it does not matter whether it is triggered by radio,which is used to test the insulation of electronic devices such as transformers.this project uses arduino for controlling the devices,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.but we need the support from the providers for this purpose,preventively placed or rapidly mounted in the operational area.due to the high total output power,generation of hvdc from voltage multiplier using marx generator,140 x 80 x 25 mmoperating temperature,cell phones are basically handled two way ratios.mainly for door and gate control,this device can cover all such areas with a rf-output control of 10,impediment of undetected or unauthorised information exchanges,transmission of data using power line carrier communication system.
This system also records the message if the user wants to leave any message,this device can cover all such areas with a rf-output control of 10,here is the project showing radar that can detect the range of an object,this project shows charging a battery wirelessly.this system does not try to suppress communication on a broad band with much power,the frequency blocked is somewhere between 800mhz and1900mhz,a mobile jammer circuit is an rf transmitter,this project uses a pir sensor and an ldr for efficient use of the lighting system.the common factors that affect cellular reception include,this project shows the system for checking the phase of the supply,that is it continuously supplies power to the load through different sources like mains or inverter or generator,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands.110 to 240 vac / 5 amppower consumption,providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements.the rf cellular transmitted module with frequency in the range 800-2100mhz,1 w output powertotal output power,radio transmission on the shortwave band allows for long ranges and is thus also possible across borders..
