Read Abstract +

Optical payloads are hosted on a range of spacecraft and reach orbit on a variety of launch vehicles. Traditionally, each payload imposes specific requirements on the mounts such as surface figure, thermal environment, and first dynamic mode. The product line of mounts described herein as the Common Optical Mount (COM) is designed to work for 80% of Lockheed Martin’s future space applications with no change to the design. Varying in diameter from 25mm to 300mm, each pre-qualified product line provides a different service needed while meeting general requirements and accommodating a wide range of unique optics (i.e. high precision alignment, large FOV systems, thick & heavy optics, lens, mirrors, beam splitters, diffraction gratings, etc.). Payload programs then leverage this qualified design and all the released piece part drawings. Additional requirements can be added to the base requirements for tailoring specific program needs. For example, the same mount product could be used to hold a fused silica beam splitter for a NASA mission in GEO orbit or a BK7 lens for a military customer in LEO orbit. Whether in a satellite constellation of a few large high-value exquisite systems or a prolificated LEO constellation of small satellites, the catalog of space qualified optical mounts serves to reduce cost, schedule, and risk for programs. COM helps deliver a payload that meets the customers future space architecture needs with improved capabilities at a fraction of the past costs.
