19 Feb 2020 | | Abstract: | The neutral particles sensor ELENA (Emitted Low Energy Neutral Atoms) for the
ESA/JAXA BepiColombo mission to Mercury (in the SERENA instrument suite) is
devoted to measure low energetic neutral atoms. The main goal of the experiment
is measuring the sputtering emission from planetary surfaces, from E=20eV up to
E=5keV, within 1D (2 deg. x 76 deg. ). ELENA original project had also a
particle discrimination system based on Time-of-Flight (TOF) of particles
through the shutter on the Micro Channel Plates detector (MCP), it has been
withdrawn from the flight model due to design and development problems. The
ELENA SCOE is the configuration/testing system of ELENA, it allows to command
operations and to set up configuration parameters on the instrument and to
monitor the incoming data. The TC/TM simulation/encoding/decoding software is
developed respecting the CCSDS/ECSS standards implemented by ESA, and it’s
SCOS2000 compatible. TC generation, HK data monitoring and basic science data
analysis are operated by the SERENA EGSE, developed by the Finnish
Meteorological Institute (FMI), Helsinki, Finland. The data stream outcoming
from the EGSE is then preprocessed from TM to user readable formats: FITS and
then ASCII csv tables with metadata collected in a detached XML file, called
label. This task is performed using the PacketLib, ProcessorLib, and DISCoS
(PPD) framework and is going to be used as the first level prototype of the
BepiColombo Science Ground Segment processing pipeline, based in ESAC, Madrid,
Spain and implemented using the PDS4 data format. | | Source: | arXiv, 2002.8759 | | Services: | Forum | Review | PDF | Favorites | |
