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.

Dutch, 51, PhD (Archaeology): SSA consultant at Leiden Observatory (Univ. of Leiden), stone age archaeologist, meteoriticist, satellite tracker, meteor observer, asteroid discoverer. Employed in an advisory role in a Space Situational Awareness project with Leiden Observatory. As an invited expert I advised members of Dutch Parliament about military satellite systems and their locations during a 2016 foreign affairs committee hearing about the MH17 disaster.
Asteroid (183294) Langbroek was named after me. In 2012, I received the Dr. J. van der Bilt Prize of the Royal Dutch Astronomy Association (KNVWS) for my work on meteors, asteroids and satellites. Opinions expressed on this blog are entirely my own.

Excerpt from United Nations resolution 2222 (XXI)

Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies


In order to promote international co-operation in the peaceful exploration and use of outer space, States Parties to the Treaty conducting activities in outer space, including the moon and other celestial bodies, agree to inform the Secretary-General of the United Nations as well as the public and the international scientific community, to the greatest extent feasible and practicable, of the nature, conduct, locations and results of such activities. On receiving the said information, the Secretary-General of the United Nations should be prepared to disseminate it immediately and effectively.
