Instrumentation

The detector NINA-2 is, in its silicon core (box D1), identical to the NINA one but making use of the extensive computer and telemetry capabilities of MITA improves the active data acquisition time.

There are two main computer systems on board: the OBDH and the PL/C. The OBDH is linked to all spacecraft systems such as the telemetry frame formatter, the interface with the active control systems, the sensors and actuators, the engineering and scientific data readout.
The role of the boxes D2, P and E is covered in NINA-2 mission by the PL/C (Payload Computer). Data from the detector are read out from the Payload Computer which performs all tasks of data readout, reduction, second level triggering and active acquisition mode switching. The PL/C can vary the trigger configuration as a result of telecommands sent from the ground station or automatically adjust the trigger configuration to cope with an increased particle flux.

All satellite and detector systems have their cold redundant counterpart with the exception of the silicon detector which has a functional redundancy in the multiplicity of the strips and the different triggers which allow to cope with eventual malfunctions.
