According to state media, it was the 30th satellite to be launched as part of the third-generation series – 59 have been launched in all since the 2000s. “The civil signal from Beidou is no better than GPS or Galileo,” said Alexandra Stickings, a research analyst at the Royal United Services Institute for Defence and Security Studies, a Britain-based think-tank told Reuters news agency in June.
