The Space Application of Timepix Radiation Monitor (SATRAM) is now in space for more than 7 years continuously measuring the radiation in Low Earth Orbit. It is attached to the Proba-V satellite, an Earth observing satellite of the European Space Agency (ESA) from an altitude of 820 km on a sun-synchronous orbit. The technology demonstration payload is based on the Timepix chip with a 300 μm...
The ESA Next Generation Radiation Monitors (NGRM) are optimized for particle detection in harsh radiation environments among which we mention solar energetic particle fluxes and South Atlantic Anomaly trapped particles. These characteristics will be precious when solar energetic particle (SEP) events will be observed along the LISA orbit. However, particle monitors optimized for high particle...
The first unit of the ESA Next Generation Radiation Monitor (NGRM) sensor - a pre-cursor of ESA distributed SWE Sensor System (D3S) – was switched on within the first hours after the launch of the European Data Relay System, Satellite-C (EDRS-C) on August, 2019. As a result, the NGRM unit has provided invaluable measurements during the GTO prior to its arrival at GEO 31 degrees East. The NGRM...
Notwithstanding notable improvements made in the last decades, the characterization of the near-Earth proton radiation environment is incomplete, with major uncertainties affecting the description of high-energy particles (>50 MeV) in the South Atlantic Anomaly (SAA) region. The Payload for Antimatter-Matter Exploration and Light Nuclei Astrophysics (PAMELA) satellite-borne experiment,...
By now the Energetic Particle Telescope (EPT) on-board Proba-V (launched on 7th May 2013 onto a polar Low Earth Orbit of 820 km altitude) has provided quasi continuously more than 7 years of flux spectra data for electrons (0.5–8 MeV), protons (9.5–248 MeV) and α-particles (38–980 MeV) with a time resolution of 2 seconds. The data are transmitted to ground 3 times per day, where within several...
Mission design is driven by human and spacecraft safety and accurate space radiation environment models are crucial. For space mission planning, flux predictions in the radiation belts are considered. For this, the AP-8 model for proton fluxes and AE-8 model for electron fluxes are used. They are empirical models of the omnidirectional trapped integral fluxes in Earth’s magnetosphere. The...
Accurate measurements of trapped energetic electron fluxes are of major importance for the monitoring of the radiation belts and for the characterization of space radiation environment. We present an inter-calibration analysis of the energetic electron flux measurements of MagEIS and REPT on-board the Radiation Belt Storm (or Van Allen) Probes (RBSP/VAP) using the measurements of the Extremely...
HelMod is a Monte-Carlo model that reproduce solar modulation process during high and low solar activity periods, in the inner and outer heliosphere, at the Earth location and outside the ecliptic plane, making it suitable for both Earth orbit studies and deep space missions.
The main time dependent parameters are solar observables like the sunspot number, the tilt angle of neutral...
