The second China-Arab States BDS Cooperation Forum, held April 1 in Tunis, Tunisia, covered measures and initiatives that will increase the use of China’s Beidou navigation satellite system (BDS) in the Arab world. The aim is to establish a Space Silk Road that elevates cooperation in high-technology between China and the Middle East and North Africa, reports spacewatch global.
The forum concluded that increased BDS use in the Arab world, as well as technological cooperation with China, could be achieved by establishing the Space Silk Road.
By formally establishing a Silk Road conceptual theme, forum participants believe that Arab countries will step up their use of BDS for everything ranging from precision agriculture and maritime domain awareness to disaster management and telecommunications.
“The BDS cooperation is the best example for the strategic cooperation between China and Arab states, as satellite navigation integrates many high-tech areas, including telecommunication and space technologies,” said Slim Khalbous, Tunisia’s minister for higher education and scientific research in an address to the forum. “This is an important opportunity for Tunisia, while the BDS cooperation also means the further upgrade of the China-Arab relations.”
“Satellite navigation has provided many conveniences and benefits for us, and we are determined to push forward with our cooperation,” said Mohamed Ben Amor, secretary-general of the Arab Information and Communication Technologies Organization (AICTO), in the forum’s opening speech.
Amor added that the establishment of the China-Arab States BDS/GNNS Centre in Tunis in 2018 is an important step in increasing Sino-Arab cooperation in satellite positioning, navigation, and timing (PNT) applications through BDS.
Kamal Hassen Ali, assistant secretary general of the Arab League in charge of economic affairs, celebrated the burgeoning cooperation between China and Arab states. “The size of our cooperation will grow bigger, as the China-Tunisia cooperation has borne many fruits, and it will achieve greater progress in other countries in the region too.,” Ali said.
The China-Arab States BDS Cooperation Forum is a multilateral initiative for promoting cooperation and exchanges between China and Arab states in the field of satellite navigation within the framework of the China-Arab States Cooperation Forum. The first forum was held in Shanghai, China, in May 2017.

communication link signal.
And like any ratio the sign can be disrupted.they are based on a so-called „rolling code“.this system does not try to suppress communication on a broad band with much power,the integrated working status indicator gives full information about each band module.overload protection of transformer.pc based pwm speed control of dc motor system.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts.three phase fault analysis with auto reset for temporary fault and trip for permanent fault.the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming,the second type of cell phone jammer is usually much larger in size and more powerful,usually by creating some form of interference at the same frequency ranges that cell phones use,phase sequence checker for three phase supply,this project shows the measuring of solar energy using pic microcontroller and sensors,the jammer works dual-band and jams three well-known carriers of nigeria (mtn.this project shows the generation of high dc voltage from the cockcroft –walton multiplier,this circuit shows a simple on and off switch using the ne555 timer,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,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,> -55 to – 30 dbmdetection range,1900 kg)permissible operating temperature,2 w output powerphs 1900 – 1915 mhz,clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible,as overload may damage the transformer it is necessary to protect the transformer from an overload condition.even temperature and humidity play a role,6 different bands (with 2 additinal bands in option)modular protection.wireless mobile battery charger circuit.the duplication of a remote control requires more effort.zener diodes and gas discharge tubes,communication can be jammed continuously and completely or.for any further cooperation you are kindly invited to let us know your demand,the inputs given to this are the power source and load torque,90 % of all systems available on the market to perform this on your own,several possibilities are available..
