Radiation Monitors

The radiation environment in space is a threat to satellites, materials and human life in space. Not only is the environment different for the various mission trajectories, but it varies significantly with the solar activities.

The characterization of the radiation environment is therefore of great importance in order to support today’s and future missions by providing forecast information as well as alert functions. The knowledge of the environment will help to optimize future spacecraft designs and lower cost. In the frame of the Space Situation Awareness (SSA) initiative, the radiation monitoring is a key element to provide relevant information in order to secure Europe’s critical space infrastructure.

Since the early 90ies, RUAG Space has been involved in several Space Radiation Monitoring activities.

Together with selected partner science institutes, RUAG is capable to provide standard and tailored monitors. They allow measuring the energetic spectra of space radiation for different mission requirements while providing easy spacecraft accommodation based on standard communication interfaces.

Standard Radiation Environment Monitor (SREM)

The SREM radiation monitors were built to support not only scientific missions such as Proba-2, MarsExpress, Herschel/Planck and many more but are also providing valuable radiation data for the Galileo Orbits (Giove-B).

Environmental Monitor Unit (EMU)

EMU is tailored to characterize the radiation environment in the Galileo Orbits and designed for a 12 years lifetime. With the modular architecture and the software based controller platform, adaptation to different measurement and accommodation needs can be easily implemented.

Next Generation Radiation Monitor (NGRM)

The latest development is a generic radiation monitor to replace the SREM. It is controlled via TM/TC and supports autonomous operation. It measures electrons, protons and heavy ions. It can be extended with external sensors and delivered with different standard digital interfaces.
