RSCO is not an enterprise, neither a
final user. It plays the function like a
"hub", as shown in Fig. 2. It initiates
some space projects based on requirements
of member countries, and then
contract them to space enterprises of
member countries. In the development
of projects, it keeps monitoring to assure
their successes.
Considering RSCO function, its
space standards should be requirement
oriented: how to make requirements,
how to perform monitoring, how to as
sure
quality and reliability, how to make
acceptance etc.. It should not make constraints
for space enterprises how to
implement requirements.
Usually, an enterprise for spacecraft
development sets 4 braches in the second
level of its space standard system:
engineering management, product
assurance, engineering, and product.
Product system construction has great
significance to such an organization,
since it's a spacecraft development enterprise
so it sets the branch of
"product". However, this branch does
not suit RSCO case, because RSCO itself
will not develop spacecraft. Also,
the spacecraft development organization
standard system includes lots of standards
for processing and manufacturing
that are not suitable to RSCO.
Usually, RSCO tasks are divided into
4 categories: space science research,
space technology and spacecraft, space
technology application, and education
and training.
RSCO mission is much similar to
ESA mission. In ECSS there is little of
standards for processing, however, there
are many standards called as handbooks
and memorandums.
Considering above mentioned
factors, there are two concepts of RSCO
space standard system studied.
·To set three branches at the second
level of the system: management,
product assurance and engineering, as
shown in Fig. 3.
·To set four branches at the second
level of the system: space science, space
technology, space technology
application, and education and training,
as shown in Fig. 4.
·Comparison of two concepts:
The branches of the first concept are
divided according to system engineering
professions. The advantages are
compatible with ECSS and China space
system, and standards of the
management, product assurance, and
engineering are separate so it is easy for
management. The disadvantage is that
all of realm (space science, space
technology, space technology
application, education and training) is
in one technical committee so there are
high requirements on leadership and
knowledge of technical committees.
The branches of the second concept
are divided according to the realm
within RSCO. The advantage is that
same realm knowledge is in a technical
committee, favorable to standard development
and management. The disadvantage
is that each branch has repetitive
standards of management and product
assurance. Another problem is not compatible
with ECSS and China space
standards.
·Final proposal:
Mainly considering the compatibility
with ECSS and China space system,
the first concept is proposed as the
framework of RSCO space system. The
standard system of various realms may
be set as shown in Fig. 5.
The system further breakdown and
coding
RSCO Space Standard System (R3S)
is the first level, containing some top
space standards,
Coding:
For the first level of standards: R3S-SS-00,
For the second level of standards:
R3S-M-00 (management),
For the third and fourth levels of management standards: as shown in Fig. 6 and 7.
For the product assurance standards, it breaks down into the third level of stan-
dards as shown in Fig. 8.
For the engineering standards, it breaks down into the third
level of standards as shown in Fig. 9.
