THE SECRET SPIES IN THE SKY - Imagery, Data Analysis, and Discussions relating to Military Space

SatTrackCam Leiden (Cospar 4353) is a satellite tracking station located at Leiden, the Netherlands. The tracking focus is on classified objects - i.e. "spy satellites". With a camera, accurate positional measurements on satellites of interest are obtained in order to determine their orbits. Orbital behaviour is analysed. This blog analyses Missile tests too.
