  • The DLR Institute of Technical Physics has developed a new generation of laser reflectors for satellites.
  • Satellites equipped with the reflectors should be able to be located with centimeter precision using lasers and at the same time be clearly identified.
  • The reflectors have additional optics for polarizing the laser light for the satellite laser ranging process.
  • Focus: space travel, security

COLOGNE, Germany (DLR PR) — The German Aerospace Center (DLR) is testing a new generation of laser reflectors for satellites. Satellites equipped with it should be able to be located from Earth with lasers and identified at the same time. The special thing about the new reflectors is the adjustable polarization optics for each satellite. These individually change the properties of a reflected laser beam, which allows the satellites to be distinguished.

A Summary of Russia’s Counterspace Capabilities
In 2009, the defunct Cosmos 2251 satellite and the Iridium 33 satellite collided in Earth’s orbit. A Livermore visualization shows the orbits of the two satellites prior to the collision among the thousands of other satellites in low-Earth orbit. The collision occurred where the two orbital paths cross near the North Pole. (Credit: Lawrence Livermore National Laboratory)

Full Report

The following excerpt from the report summarizes Russia’s counterspace capabilities.

There is strong evidence that Russia has embarked on a set of programs over the last decade to regain many of its Cold War-era counterspace capabilities. Since 2010, Russia has been testing technologies for rendezvous and proximity operations (RPO) in both low Earth orbit 9LEO) and geosynchronous Earth orbit (GEO) that could lead to or support a co-orbital anti-satellite (ASAT) capability. Evidence suggests at least two active programs: a new co-orbital ASAT program called Burevestnik that is potentially supported by a surveillance and tracking program called Nivelir.
