                         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.",
