Description
The LEGRI Science Operation Center (SOC) is the single contact point
between the MINISAT-01 Centro de Operaciones Científicas (COC)
located at Villafranca del Castillo (Madrid) and the LEGRI Consortium.
Its architecture, operational procedures and associated software has
been developed at the Universities of Valencia and Birmingham on the
scope to define a integrated Data Analysis System, able to perform the
daily follow-up of the instrument health, raw data files decompression
and archiving activities (on-line and historical). Pointing and
telecommand files generation is also a SOC responsibility. The aim of
this paper is to report the SOC activities during the two years of LEGRI
operations. Conclusions about the SOC architecture and procedures
evolution on how to handle the operations for space-borne
instrumentation, are also presented. Special attention has been paid to
the operative evaluation of the pointing reconstruction solutions from
the MINISAT-01 Attitude Control System by comparing them with those
obtained with the LEGRI Star Sensor. The analysis of one year of
observations shows the good agreement between both sets of data. No
systematic deviations have been found with an averaged standard
deviation of 1 degree in alpha and delta coordinates. For most of the
time the MINISAT pointing system is working slightly better than
expected and within specifications.
