Title:
OPTICAL COARSE POINTING ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2023/060450
Kind Code:
A1
Abstract:
An optical coarse pointing assembly, CPA, (4) of an optical communication terminal, OCT, (1), said optical coarse pointing assembly (4) being adapted to establish and/or maintain an optical communication link (OCL) between the optical communication terminal, OCT, (1) and an external optical flight platform, wherein the optical coarse pointing assembly (4) has a CPA mirror (4A) adapted to reflect an optical beam received from the external optical flight platform into a telescope (3A) of an optical head unit (3) of said optical communication terminal, OCT, (1) and/or to reflect an optical beam received from the telescope (3A) of the optical head unit (3) of said optical communication terminal, OCT, (1) to the external optical flight platform, wherein the CPA mirror (4A) of said optical coarse pointing assembly (4) is pivotable around an elevation axis (4B) located off a center of gravity, COG, of said CPA mirror (4A).
