Abstract (in Japanese) (See Japanese page) 
(in English) To provide a satellite communication system with high reliability for social infrastructure, building flexible beam adapting to change of communication traffic is necessary. Optical Beam Forming Network has capability of broadband transmission and small light construction. However, in space environment there are concerns that drop of reception efficiency caused by relative phase shift of received signal among antenna elements with temperature fluctuation. To prevent this, we control relative phase among received signals with Optical Phase Locked Loop. In this paper, we evaluated stability of relative phase among 3 elements for temperature fluctuation at multiplexer from -15 to 45$^{circ}$C, and checked the stability of PLL among 3 elements.
