I am working on a project, which consists of the launch of 8 cubesat 1U to LEO (Low Earth Orbit) and I started working on the launch part, the idea of the project is to be as cheap as possible, the problem is that cubesats have to be separated, at the same distance (or approximate) from each other to create a "full-time" communication network for probes and satellites to saturn and jupiter moons. and I'm looking for a rocket capable of launching these 8 cubesats in a zolo launch, the total load will be 0.8 kg per cubesat so there will be a total weight of approximately 6.5kg. The distancing could make it the last stage of the rocket or it could add a small stage of cold gas to each cubesat to make the distancing themselves, but that would add more weight to the payload. What rocket do you recommend? Which method is cheaper, the distance by cold gas or using the last stage and go dropping cubesats?
