- Abstract
According to Korean national space development plan, lunar orbiter is scheduled to be launched in 2020. Through communication link, ground station in lunar mission is responsible to receive telemetry signal including sensor data from lunar orbiter and to transmit telecommand to lunar orbiter. At a preliminary stage of development for the Korean ground station in lunar mission, detailed link analysis was firstly conducted to establish the required performances of ground station with considering several mission profiles of lunar orbiter after separating from launch vehicle. To meet the required performance for lunar mission, in this paper, combining of several small antennas is proposed instead of using conventional large antenna more than 18m of antenna diameter. In terms of development cost and operability, small antenna has more merits than large antenna. For the evaluation on the effect of combining small antennas, two 3.7m mesh-type antenna in geostationary mission were applied. As a result of combining two small antennas, it was shown that around 2.6dB of combining gain was achievable.
