Design of Radio Beacon for Spacecraft-memory Localization

With the development of space technology and more and more space experiments, it has brought forward higher requests for memory of hard-recovered solid-state recorders. Therefore, Recovery of the memory becomes more important. Aiming at the disadvantages of present ways of recycling, we introduce a real-time GPS positioning wireless beacon which can be applied in memory recovery. This paper introduces the principle of the system, circuit, and the function that can realized. Experimental results show that the beacon in a static environment and dynamic environment had a good performance in GPS positioning, and a high positioning accuracy. During Signal transmission, the receivers can receive the raw GPS signal without error and can depict the running track of memory.
