The Lander Operations Control Centre (LOCC) was located at the National Space Centre in Leicester, from which the spacecraft was being controlled, and was visible to the public visiting the centre. The control centre included operational systems for controlling "Beagle 2", analysis tools for processing engineering and scientific telemetry, virtual reality tools for preparing activity sequences, communications systems, and the Ground Test Model (GTM). The GTM was composed of various builds of the "Beagle 2" systems, collected together to provide a full set of lander electronics. The GTM was used nearly continuously to validate the engineering and science commands, to rehearse the landing sequence, and to validate the onboard software.
