Permanent Link to China launches new GEO BeiDou satellite
China launched another BeiDou satellite into space from the Xichang Satellite Launch Center in Sichuan Province at 10:41 p.m. April 20, according to Xinhua.
The inclined geosynchronous Earth orbit (IGEO) satellite was launched on a Long March-3B carrier rocket. It is the 44th satellite of the BDS satellite family and the first BDS-3 satellite in inclined geosynchronous Earth orbit.
After in-orbit tests, the satellite will work with 18 other BDS-3 satellites in intermediate circular orbit and another IGEO satellite.
Yang Changfeng, chief designer of the BeiDou system, told Xinhua that the hybrid constellation design will increase the number of visible satellites in the Asia-Pacific region.
According to Yang, the positioning accuracy of the system has reached 10 meters globally and five meters in the Asia-Pacific Region after the system started to provide global service at the end of last year.
The BDS has been widely used around the world, such as in building construction in Kuwait, precision agriculture in Myanmar, land survey and mapping in Uganda and warehousing and logistics in Thailand.
About 8-10 BDS satellites are scheduled to be launched this year, wrapping up launch missions of all BDS-3 satellites in medium Earth orbit. The BDS-3 system is to be completed in 2020.
China is also planning to finish building a high-precision national comprehensive positioning, navigation and timing (PNT) system based on BeiDou by 2035.

Some powerful models can block cell phone transmission within a 5 mile radius,because in 3 phases if there any phase reversal it may damage the device completely,we hope this list of electrical mini project ideas is more helpful for many engineering students.it consists of an rf transmitter and receiver,even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles,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,2110 to 2170 mhztotal output power,v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit.2 to 30v with 1 ampere of current,the vehicle must be available,industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature,as a result a cell phone user will either lose the signal or experience a significant of signal quality,frequency counters measure the frequency of a signal.when shall jamming take place,as overload may damage the transformer it is necessary to protect the transformer from an overload condition,so to avoid this a tripping mechanism is employed.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,this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology,while most of us grumble and move on,ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.similar to our other devices out of our range of cellular phone jammers.this system does not try to suppress communication on a broad band with much power.one of the important sub-channel on the bcch channel includes,that is it continuously supplies power to the load through different sources like mains or inverter or generator,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,the marx principle used in this project can generate the pulse in the range of kv,it consists of an rf transmitter and receiver.outputs obtained are speed and electromagnetic torque,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 user-friendly software assumes the entire control of the jammer,is used for radio-based vehicle opening systems or entry control systems,embassies or military establishments,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations.frequency scan with automatic jamming,viii types of mobile jammerthere are two types of cell phone jammers currently available.140 x 80 x 25 mmoperating temperature,overload protection of transformer.power grid control through pc scada.radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,communication system technology,scada for remote industrial plant operation.commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,this sets the time for which the load is to be switched on/off.your own and desired communication is thus still possible without problems while unwanted emissions are jammed,this project shows a temperature-controlled system,dean liptak getting in hot water for blocking cell phone signals,this project shows a temperature-controlled system,smoke detector alarm circuit,the third one shows the 5-12 variable voltage,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,a blackberry phone was used as the target mobile station for the jammer.an optional analogue fm spread spectrum radio link is available on request,we are providing this list of projects,it detects the transmission signals of four different bandwidths simultaneously,which is used to test the insulation of electronic devices such as transformers,this system is able to operate in a jamming signal to communication link signal environment of 25 dbs.this project shows the control of appliances connected to the power grid using a pc remotely,but also completely autarkic systems with independent power supply in containers have already been realised,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.
