Team Stellar is finishing Communications, Navigation and Data plans
Communications, Navigation and Data Transfer are critical for any space mission, and for our GLXP mission as well. On one side, it is needed to control and observe the vehicles and on the other side it is needed for the mandatory GLXP data transfer from the lunar surface.
The main consideration is redundancy. Symetrical redundancy includes two systems which are the same, like, for example, two electrical systems on a passenger jet. Both have the same generators, wires, circuit breakers and controls. If one fails, the other one will take over. In our case, this would imply two identical cameras, antennae etc. The assymetrical redundancy implies two systems which are not identical, but serve the same/similar purpose. A good example for this is to have a solar panel and a battery as the electrical power source.
Team Stellar has designed a system which covers all flight phases, to include as much redundancy as possible, while observing the limitations of mass, size and power budgets.
Our CTO Vilko Klein offered the lates revision of the documents for feedback to our team members. We are looking forward to continuing our communications tests.
