Abstract: Operation concept is a discipline addressed by system engineers very early in satellite development cycle. Mission requirements are analyzed taking into account power consumption and data rate each payload needs. Dealing with the limited power budget available in CubeSat-based missions is a challenge. In this paper we show the usage of the satellite simulator developed by Chagas [1] at INPEs Space Mission Integrated Design Center (CPRIME), in the analysis of the NanosatC-BR2 issues regarding operation concept of its payloads. NanosatCBR2 is INPEs second scientific CubeSat, expected to be launched by early 2019. The simulator encompasses orbital propagation, power generation and consumption, equipment usage, the use of mass memory for On Board Data Handling (OBDH) tasks, and communication with ground stations for science data download. The focus of the simulations was to verify plausible mission operation concept with regards to the power and data budgets considering the operation of the three physical payloads onboard the satellite. Each simulation scenario varied the individual operations of each payload relative to the orbital period and data generation limits. The simulation results highlight scenarios in which power and data budgets are balanced in order to meet the operation requirements of each payload. These scenarios were very useful to the NanosatC-BR2 team to make the decision concerning the feasible implementation.
