FIPEX on QB50 Date: 06.02.2013--- DRAFT---- Issue: 1.0.2ICD Page: 22 / 254. Mechanical interface4.1 Accommodation and Field of ViewThe Science Unit will be accommodated at one end of the CubeSat, on a 10 mm x 10 mmface. The vector normal to this face shall be in the spacecraft ram velocity direction. Thisface shall not be available for solar cells and nothing must project forward of this face.Depending on the integration procedure of the payload module it might be possible to usethe outer free area of the sensor unit top plate for mounting sensors or other smallcomponents. These components must be smaller than 4.5 mm. Please refer to the ICDDrawing in Appendix 1 for details.
