Standard reg. Terminology (ECSS-E-ST-60-20C):
Product Data in MBSE Tools

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!
