CubeSat-based nanosatellites are composed of COTS components and rely on its structure and standardized interfaces. A challenge in the nanosatellites context is to adapt the V\&V (Verification and Validation) process to answer to the increase importance of the embedded software, to reduce the artefacts to be delivered aiming at cutting cost and time and still complying with international standards. This work presents an analysis of the strategy adopted in a real nanosatellite for the development of the OBDH software embedded in NanosatC-BR2 mission. The goal is to discuss the impact that the standardization of the structure and interfaces of the CubeSat impose on the V\&V process of the SiS and to highlight the challenges of ``New Space Age`` for the use of existing V\&V techniques and methods.

太空技术演进对嵌入式软件密集型系统V \＆V的影响

基于CubeSat的纳米卫星由COTS组件组成，并依赖于其结构和标准化接口。纳米卫星方面的挑战是适应V \＆V（验证和确认）过程，以应对嵌入式软件日益增长的重要性，减少旨在减少成本和时间并仍符合国际标准的假象。这项工作对在实际的纳米卫星中采用的策略进行了分析，以开发嵌入在NanosatC-BR2任务中的OBDH软件。目的是讨论CubeSat的结构和接口的标准化对SiS的V \＆V过程的影响，并强调使用现有V \＆V技术的``新太空时代''的挑战和方法。
