论文摘要
ESA/JAXA BEPICOLOMBO任务（在Serena仪器套件中）的中性颗粒传感器ELENA（发出的低能量中性原子）用于测量低能能中性原子。实验的主要目标是测量行星表面的溅射发射，从E = 20EV到E = 5KeV，在1d（2摄氏度x 76度）之内。 Elena原始项目还具有通过微通道板检测器（MCP）上快门的飞行时间（TOF）的粒子歧视系统，由于设计和开发问题，它已从飞行模型中撤回。 Elena SCOE是Elena的配置/测试系统，它允许命令操作并设置仪器上的配置参数并监视传入数据。 TC/TM仿真/编码/解码软件是针对ESA实现的CCSD/ECSS标准而开发的，并且它的SCOS2000兼容。 TC生成，HK数据监测和基础科学数据分析由芬兰赫尔辛基的芬兰气象研究所（FMI）开发的Serena EGSE经营。然后将来自EGSE的数据流从TM到用户可读格式进行预处理：拟合，然后将ASCII CSV表和元数据收集在一个分离的XML文件中，称为标签。 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.
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based on Time-of-Flight (TOF) of particles through the shutter on the Micro Channel Plates detector (MCP), it has been withdrawn from the flight model due to design and development problems.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.
