Preliminary jitter stability results for the large UV/optical/infrared (LUVOIR) surveyor concept using a non-contact vibration isolation and precision pointing system
Lia W. Sacks,Carl Blaurock,Larry Dewell,Kiarash Tajdaran,Kuo-Chia Liu,Christine Collins,Garrett West,Kong Q. Ha,Matthew R. Bolcar,Julie A. Crooke,Jason E. Hylan,Raymond M. Bell +11 more
TL;DR: The wavefront error and Line- Of-Sight (LOS) jitter performance is discussed in this paper when using the Vibration Isolation and Precision Pointing System (VIPPS) being developed cooperatively with Lockheed Martin in addition to a multi-loop control architecture.
Proceedings ArticleDOI
Dynamic stability with the disturbance-free payload architecture as applied to the Large UV/Optical/Infrared (LUVOIR) Mission
Larry Dewell,Kiarash Tajdaran,Raymond M. Bell,Kuo-Chia Liu,Matthew R. Bolcar,Lia W. Sacks,Julie A. Crooke,Carl Blaurock +7 more
TL;DR: The system-level analysis of a non-contact architecture is presented for LUVOIR, based on requirements that are directly traceable to its science objectives, including astrophysics and the direct imaging of habitable exoplanets.

TL;DR: The Origins Space Telescope as mentioned in this paper was designed to trace the history of our origins from the time dust and heavy elements permanently altered the cosmic landscape to present-day life, and it was the first telescope to operate at mid-and far-infrared (IR) wavelengths.
Proceedings ArticleDOI
Dynamic wavefront error and line-of-sight performance predictions for the 15-meter segmented Large Ultraviolet/Optical/Infrared Surveyor (LUVOIR) with non-contact vibration isolation
Larry Dewell,Alison Nordt,Ankur Chopra,Matthew R. Bolcar,Julie A. Crooke,Michael Jacoby,Kiarash Tajdaran,Torben B. Andersen +7 more
TL;DR: A study of predicted dynamic WFE performance of the LUVOIR-A architecture during steady-state operation of the coronagraph instrument, using an integrated model consisting of a segmented primary mirror, optical sensitivities, steering mirror and non-contact isolation, and control systems.
Proceedings ArticleDOI
Telescope line-of-sight slew control and agility with non-contact vibration isolation for the large ultraviolet/optical/infrared (LUVOIR) surveyor concept
Kiarash Tajdaran,Larry Dewell,Eric V. Eason,Raymond M. Bell,Kuo-Chia Liu,Matthew R. Bolcar,Lia W. Sacks,Julie A. Crooke,Carl Blaurock +8 more
TL;DR: An integrated pointing control architecture is described that enables largeangle slewing of the telescope, while maintaining non-contact between telescope and spacecraft, in addition to meeting the LUVOIR line-of-sight agility requirement.
