AbstraktAbstract

In this contribution the response of the SATRAM/Timepix spacecraft payload to space radiation in Low Earth Orbit in the form of full Timepix frames along a single satellite orbit is presented. The compact light weight SATRAM payload has been operating in open space on board ESA’s Proba-V satellite in low Earth orbit since May 2013. The embedded Timepix chip can determine the composition and spectral characteristics of ionizing radiation in the satellite environment together with visualization of single particle tracks. The device provides single quantum X-ray photon and charged particle counting for high sensitivity detection, high resolution tracking and directional visualization of energetic charged particles over a wide dynamic range of particle fluxes, energies and broad field of view. In addition to the visualization of the varying radiation environment along a single satellite orbit also preliminary evaluated results in the form of total particle flux maps (navigation correlated spatial and time distributions) along the satellite orbit for a period of 19 days in October 2014 are included.
