Stby=Idle?

By today supplier

information is often

transferred manually

by a user.

Tomorrow the data

transfer process

happens

automatically – the

user only selects a

product.

Parameter Names in MBSE Tools

MBSE Tool Virtual Satellite 4 VSD OCDT / CDP4

Mass Parameters massPerUnit (kg) Weigth (gram) mass (kg) mass margin

Structure Parameters radius (m) shape sizeX (m) sizeY (m) sizeZ (m)

Height (millimetre) Length (millimetre) Width (millimetre)

diameter (m) shape height (m) length (m) width (m)

The parameter names for Virtual Satellite 4 and VSD were taken from installations of the tools. OCDT and CDP4 directly implement the ParameterType concept from ECSS-E-TM-10-25. At Virtual Satellite, the margin parameters are not defined at Equipment level, but above.

massPerUnit = mass?

What to do about weigTH? sizeX = Height?

Or Length?

What if

VSD: sizeX = Height

OCDT: sizeX = length

?

Ok, so maybe we can‘t exchange data between

MBSE tools, but that was not the goal.

Develop API with manufacturers

Both based on ontologies – a common

semantic understanding is necessary!
