Summary:
Engineering test satellite Ⅷ(ETS-Ⅷ) was launched at December 2006. Many communication technologies are experimented and evaluated the performances. This Satellite is equipped with the large deployable reflector antenna (LDRA) for land mobile communications with the size of 17m x 18 m, which is one of the largest size for communications satellite. First, we describe the measurement of radiation patterns of this antenna on orbit, Comparing the measurement and calculated results, actual beam positions are little bit shifted and beam shapes are distorted. Next we discuss the collection plan of weight of array feed.
