欧洲空间局的“乔托”(Giotto)飞行器和地球之间建立了高增益的通信链路,这条链路约有7亿公里。该飞行器在今年3月13日探测哈雷彗星时,传输了探测数据。飞行器正确的定向和高增益消旋天线,使无线电波束始终指向地球。乔托飞行器在位于西德达姆斯丹特欧空局地面站控制下,所有系统都工作正常。它 A high-gain communications link was established between the European Space Agency’s Giotto aircraft and the Earth, about 700 million kilometers. The aircraft transmitted sounding data when it detected Halley’s comet on March 13 this year. The correct directional and high-gain deconvolution antenna for the aircraft directs the radio beam to the Earth. Giotto was operating normally under the control of the ground station at the Düsseldorf-Dandenrhein airport in Stedehand. it
