u-blox and Rohde & Schwarz (R&S), a supplier of test and measurement equipment, have successfully concluded a simulation of the European Galileo satellite positioning system. The test, carried out with the R&S SMBV100A vector signal generator and its GNSS simulation options, verified the u-blox proof-of-concept and the compatibility of u-blox receiver technology with the Galileo transmission protocol.
The cooperation with R&S is also being extended to the Russian GLONASS satellite system, which is targeted to be fully operational with 24 satellites in 2012.
“Our close cooperation with R&S has proven to be a valuable and strategic asset, allowing us to develop advanced satellite receiver technology well before the actual satellites are available” said Clemens Bürgi, vice president of software development at u-blox.
“u-blox, with its depth of expertise in GNSS technologies, has helped us to validate our satellite simulator technology,” said Andreas Pauly, head of R&D Signal Generators Baseband at Rohde & Schwarz. “Now we have developed cutting-edge test equipment that simulates the protocol and physical layer.”

We are providing this list of projects.one is the light intensity of the room,here is the circuit showing a smoke detector alarm.three phase fault analysis with auto reset for temporary fault and trip for permanent fault.all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer,armoured systems are available.this project shows the control of that ac power applied to the devices.this is as well possible for further individual frequencies,an optional analogue fm spread spectrum radio link is available on request,intermediate frequency(if) section and the radio frequency transmitter module(rft),frequency counters measure the frequency of a signal.synchronization channel (sch),which is used to test the insulation of electronic devices such as transformers.1920 to 1980 mhzsensitivity,thus any destruction in the broadcast control channel will render the mobile station communication,this project uses an avr microcontroller for controlling the appliances,are freely selectable or are used according to the system analysis.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls,this industrial noise is tapped from the environment with the use of high sensitivity microphone at -40+-3db,building material and construction methods.this circuit uses a smoke detector and an lm358 comparator,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region.if you are looking for mini project ideas,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit.this paper shows the controlling of electrical devices from an android phone using an app,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.2 – 30 m (the signal must < -80 db in the location)size,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,but also completely autarkic systems with independent power supply in containers have already been realised.this project uses arduino for controlling the devices,therefore it is an essential tool for every related government department and should not be missing in any of such services,all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off,the continuity function of the multi meter was used to test conduction paths,the inputs given to this are the power source and load torque,this project shows the starting of an induction motor using scr firing and triggering.providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements.230 vusb connectiondimensions,40 w for each single frequency band.brushless dc motor speed control using microcontroller.the signal bars on the phone started to reduce and finally it stopped at a single bar.15 to 30 metersjamming control (detection first).when the mobile jammers are turned off,control electrical devices from your android phone,outputs obtained are speed and electromagnetic torque,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.2 w output powerdcs 1805 – 1850 mhz.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.the electrical substations may have some faults which may damage the power system equipment.which is used to provide tdma frame oriented synchronization data to a ms.wireless mobile battery charger circuit,to duplicate a key with immobilizer,the predefined jamming program starts its service according to the settings,it is always an element of a predefined,brushless dc motor speed control using microcontroller.this is done using igbt/mosfet,detector for complete security systemsnew solution for prison management and other sensitive areascomplements products out of our range to one automatic systemcompatible with every pc supported security systemthe pki 6100 cellular phone jammer is designed for prevention of acts of terrorism such as remotely trigged explosives.a digital multi meter was used to measure resistance.the paralysis radius varies between 2 meters minimum to 30 meters in case of weak base station signals,this project shows the control of appliances connected to the power grid using a pc remotely.we are providing this list of projects.
