The experiment is composed of two main boxes. Inside the gondola there are all electronic components: An Onboard Computer, an Onboard Data Handling Unit, a Power Distribution Unit and for each camera a preprocessing board. On the outside there is the sensor box including a near infrared camera, a visual light camera and a mini spectrometer and their redundant counterparts. Those will be mounted separately, but in the same configuration. This shifted box is necessary to provide an unrestricted field of view downwards.
