| Abstract(in English) | NASA and ESA have taken advantage to use Ka-band (32GHz) for the purpose of higher-rate data transmission, more precise orbit determination, and radio science tools for planetary explorations. JAXA has developed a next generation X-band deep space digital transponder for our deep space programs such as Planet-C and MMO. As a next step, we will soon give a Ka-band coherent transmitter function to extend this X-band transponder capability. We will discuss primary design on this Ka-band transmitter attachment. We are also interested in a highly stable onboard oscillator which limits availability of Ka-band telecommunications in deep space. We will introduce our approach to JAXA's USO (ultra stable oscillator) and its in-house validation method for future development. |
