A contract has been signed between ESA and RUAG Space (CH) in collaboration with PSI (CH), EREMS (F), Gamma Medica-Ideas (N) and ONERA (F) for the development of the Next Generation Radiation Monitor (NGRM). The project kicked-off on 14 September 2011 and has a planned duration of 18 months.

Spacecraft are exposed to a complex radiation environment which is highly variable and at times very strong. This environment consists of energetic particles from solar events, of trapped particle belts, and of high-energy cosmic rays. Particle species encountered include electrons, protons and heavy ions. Some dramatic space system failures and disturbances in recent years have been concluded to be due to radiation-induced malfunction of critical electronic parts.

To characterise and predict these environments, and to support radiation effects studies and spacecraft anomaly investigations, radiation monitoring instruments should be flown on as many spacecraft as possible. To address these issues, in the 1990s ESA successfully established the Standard Radiation Environment Monitor (SREM) programme. A batch procurement of SREM units led to them flying on STRV-1c, Proba-1, Integral, Rosetta, Giove-B, Herschel and Planck.

As follow-on to the SREM, ESA together with various partners in other Agencies, institutes and Industry initiated the development of a more advanced and compact instrument, the Next Generation Radiation Monitor (NGRM). The present activity addresses the Phase B/C/D development of the instrument, culminating in the manufacturing of the first NGRM Flight Model unit.
