First for the site of the scientist: the Dokifat 3 satellite suddenly returned to operation and broadcasting after two years

  • 3 תגובות
According to David Greenberg, a satellite communications instructor at the Herzliya Science Center, the listening was accidental but was made possible by the fact that Dokifat 3 transmits in the same frequency range as the terrestrial satellites. Now the students of the science center, whose class before them launched it, are trying to understand what happened
