In the next future Small satellites can be used as experimental platforms improving their capabilities. It has been demonstrated that nanosatellites or picosatellites using the technology of CubeSats are being developed by different universities around the world. Which missions are possible to execute or which payloads can be installed in a such a satellite platform? Small satellites are conceived as dedicated systems to execute experiments or tests in space. We can compare a small satellite platform with others systems. A Drop Tower will be used to create some seconds (aprox. 10s) of microgravity. With S ounding Rockets the generated microgravity will take some minutes (max 14 min). With a small satellite platform the microgravity condition will result in months or longer! From this point of view small satellites have obviouslly much advantage than a drop tower or a sounding rocket by executing experiments in microgravity. For sure the others systems have also advantages like an intact experimental pay load (Drop Tower), or the recovery of the payload and recorded data in short time just after the flight (S ounding Rocket) but for a small satellite this system functionality can also be developed, so that the payload can be also recovered intact or the data provided to ground as quick as possible. Peruvian engineers are working on a next generation of subsyste ms and payloads to be implemented in such experimental platforms. They are modelling and improving the capabilities of some, used in sounding rocket systems, importants instruments which can be carried in the proposed small satellite Platform. The instruments must be simplified, reduced in size, adapted and designed to properly perform their functions in the designed platform. All the subsystems will continually be designed for making them more efficient in order to use best possible the limited resources available in the satellite. Depending of the mission a next generation of pico satellites can emerge.
