An important aspect of any space instrument is calibration. This means knowing and understanding the performance of the instrument in terms of sensitivity, resolution, noise factors. Even when these aspects are known, the work continues, as various parameters change with time, temperature and radiation dose in space. So calibration is a combination of testing the instrument before launch against known standards, and monitoring performance in orbit (e.g. regular specific observations of standard astronomical objects). At MSSL we have calibration experts whose role is to monitor and maintain the performance of instruments using a combination of pre-launch and in-flight testing and monitoring.

Currently we are involved with the in-orbit calibration and monitoring of:
