TITLE: QB50 m-NLP Science Unit Interface Control DocumentDoc. No. MSSL-QB50-ID-12001-DRAFT a6 Mechanical interface6.1 Accommodation and Field of ViewThe Science Unit will be accommodated at one end of the CubeSat, on a 10 x 10 face.The vector normal to this face shall be in the spacecraft ram velocity direction. This faceshall not be available for Solar cells, any other sensor or subsystem and nothing mustproject forward of this face.Figure 6-1 – m-NLP Science Unit Keepout Areas within CubeSat6.2 Interface control drawingThe mechanical interface drawing is provided in Appendix 1. The Science Unit isdesigned to interface to commercially available CubeSat structures either through anadapter or through appropriate relocation of mounting holes on the structures.Page 23 of 27
TITLE: QB50 m-NLP Science Unit Interface Control DocumentDoc. No. MSSL-QB50-ID-12001-DRAFT a6.3 M-NLP boom systemFigure 6-2 – m-NLP Science Unit Boom SystemThe m-NLP boom system consists of four separate booms, mounted on the commontop plate of the SU. Each of the booms has an individual deployment mechanism,operated by the m-NLP PCB on command from the OBC. The m-NLP boom systemdrawing is provided in Appendix 2.6.4 Surface finishThe overall finish for the Aluminium structure of the Science Unit shall be Alocrom1200.6.5 MassThe total Science Unit mass shall be < 600 grams.7 Attitude ControlThe CubeSat shall provide attitude control with a pointing accuracy of +/-10° andpointing knowledge of +/-2° (TBC).8 Cleanliness and ContaminationAll materials shall meet or exceed the following outgassing criteria:TML ≤ 1.0% .CVCM ≤ 0.1% .Where possible, materials shall be selected from ESA and NASA approved lists andprocessed in such a way as to minimize contamination.9 Operating ConditionsThe particular operating conditions will depend upon the selection of sensors for a givenScience Unit. These will be made known at the time of selection.Page 24 of 27
