GOCE Calibration and Monitoring Facility (CMF)

Abstract

The CMF is responsible for the calibration (the nominal calibration is done in PDS/IPF1, but the CMF is responsible for the assessment and approval of the calibration products) and the monitoring of the space segment, as well as the monitoring of the performance of the PDS products, in particular the calibration products.

The CMF consists of a combination of generic and specific functionality. Generic tools are such that they can be applied to any type of data time series (i.e. both science and HK products) while specific toolboxes shall be developed for the analysis of GOCE products. These specific toolboxes include: Gradiometer Instrument Monitoring Functions, Satellite-to-Satellite Tracking Instrument Monitoring Functions, Drag-Free and Attitude Control System Monitoring Functions and Gradiometer In-Flight Calibration Monitoring Functions. It is required to have the capability to add further toolboxes during mission operations.

The different tools of the CMF run in either automatic or interactive mode. When in automatic mode the tools are used for systematic quality analysis of the calibration data and products. When in interactive mode, the tool is run by an operator and by the Calibration and Monitoring (CM) team having the required experience to analyse the data of the PDS and to propose modifications to the mission planning (extra calibration, downlink of diagnostic HK parameter, etc.).
