Following our previous article Signal intelligence 101: SIGINT targets, which described what kind of intelligence the USA could collect by targeting a variety of Soviet electronic emitters, Rob1 and I assembled an history of the high-altitude satellites which performed the collection. In the same fashion as History of the US reconnaissance system, which focused on… Continue reading History of the US high-altitude SIGINT system

So here is a quick overview of the various types of signal intelligence targets, with an emphasis on the Cold… Continue reading Signal intelligence 101: SIGINT targets

According to the press, this satellite will be operated by the BND, Germany's foreign intelligence service. Such a purchase breaks from the German tradition of operating only radar satellites, under the control of the military, and thus marks an unexpected shift in… Continue reading A new German space policy?

It has not always been this way: contrary to the USA or the USSR, France has never had film-return optical satellites, and orbited its own space reconnaissance systems roughly 30 years later than them. In… Continue reading History of the French reconnaissance system

I wanted to make a short post on today's US spy satellites, but I realized that to speculate about them, it's better to have some historical perspective. So I assembled a condensed history of the US reconnaissance system (only for imagery, the electronic side might come later). I used Susan D. Schultz's chronology in Why… Continue reading History of the US reconnaissance system
