abstract = "The use of small satellites platforms based on Cubesats standard
is an increase demand for space science development, improving
research, exploration and validation of new space technology in
orbit. These space missions have grown by an average of 39 percent
per year since 2010 with an expectation of more than 400
nanosatellite/microsatellite annual launches by 2022. Cubesats are
no longer purely educational or experimental tool, quality
assurance and proper metrics to achieve the compromise between
reliability, cost and performance is currently mandatory. Due to
the short duration of the nanosatellite development cycle using
Cubesats and the low-cost project the traditional space standards
for development and testing infrastructure are infeasible.
Initiatives on standardization for CubeSats have been proposal as:
TISEG (Test in Space Easy Guidelines), whose goal is optimize the
communication between the payload developers and the integrators
by standardize the payload integration; Cubesat Standard Handbook
aims to improve the overall reliability of CubeSats and increase
the level of cooperation among CubeSat community. Considering the
significant time consuming of testing activities during the
development of a space system, approximately 50 percent compared
to other activities, and more than 50 percent of the total project
cost, our research focuses on reducing the verification,
validation and tests activities of Cubesats based projects.
Although a well-defined platform specification exists, the system
engineers still facing a serious setback, extending the project
schedule from the kick-off to the effective launch. A paradigm
change in VVT (Verification, Validation and Testing) process is
required once the cubesats missions are carrying new technologies
not enough mature on board. By the ISO 16290:2013 scale, TRL
(Technology Readiness Level) 6 corresponds to the appropriate
technology readiness level for supporting the decision to go for
implementation with acceptable risks. Reaching this level means a
well-defined set of reproducible processes to demonstrate that the
element meets a set of operation requirements in the real
environment. However, the time or effort to move from one TRL to
another is technology dependent being not linearly connected to
the TRL scale. They can vary widely depending on the element and
mission under consideration. Focusing on the integration of OBDH
(On-board data handling) system with different payloads as case
study of NanoSatC-Br2 project, the proposed VVT approach for
reducing system development time is discussed. The process is
guided by evidences of increase maturity level of each payload
along its implementation phase and integration with OBDH system.",
