In the next 6 years, over 3000 nano/cubesats launches are expected. This is a segment of the satellite market that has attracted investors’ attention. Recent advances in electronics have led to the miniaturization of components, reduction of power consumption, and significant performance and reliability increase, besides cost reduction. This advance benefited not only the satellite market but also the aerospace sector, in particular for launchers. This work presents a study of the use of technologies, motors and subsystems already developed in the Brazilian Space Program for application in orbital launch systems for micro-satellites and cubesats. Small rocket launcher configurations are studied for access to space with low cost and adequate reliability. This work proposes the use of the VL-3 and VL-4 vehicles, developed from the VSB-30 and VS-40 suborbital rockets respectively. Their capacities are of carrying payload masses from 8 to 11 kg for VL-3 and from 23 to 35 kg for VL-4, for the orbits studied. Two new solid motors, with propellant mass of 292 and 50 kg, would need to be developed for the application in the upper stages of the VL-3 and VL-4 vehicles. The technologies involved are accessible, known and already used in the Brazilian Space Program. The results were promising, and new studies are indicated for the detailing of the proposed ideas.
