A Beidou systems satellite is now believed to have experienced past interference from a complex electromagnetic environment, which cut off signal transmissions in 2007, People's Daily reported. Thanks to the team of scientists at Beidou, they were able to overcome the interference issue in less than three months by 2008.
Wang Feixue, a scientist specializing in the Beidou navigation system and a senior colonel in the People's Liberation Army said, “Had they not been able to recover the signal within three months, future satellite launches would have been indefinitely delayed. And satellites already launched would have been put out of operation.
