Differential optical shadow sensor for sub-nanometer displacement measurement and its application to drag-free satellites
Andreas Zoellner, Si Tan, Shailendhar Saraf +4
We present a method for 3D sub-nanometer displacement measurement using a set of differential optical shadow sensor. It is based on using pairs of collimated beams on opposite side…
The Design of a Drag-Free CubeSat and the Housing for its Gravitational Reference Sensor
Carlo Zanoni, Abdul Alfauwaz, Ahmad Aljadaan +11
A Drag-Free CubeSat mission has been proposed to demonstrate the feasibility of a Gravitational Reference Sensor (GRS) with an optical readout for a 3 units (3U) spacecraft. A pure…
LISA-2020: An Intermediate Scale Space Gravitational Wave Observatory for This Decade
S. Buchman, J. A. Lipa, R. L. Byer +10
Over the last three decades, an exceptionally good science case has been made for pursuing gravitational wave (GW) astronomy. This has engendered a worldwide effort to detect the e…
Integrated Differential Optical Shadow Sensor for Modular Gravitational Reference Sensor
Andreas Zoellner, Eric Hultgren, Ke-Xun Sun
The Laser Interferometer Space Antenna (LISA) is a proposed space mission for the detection of gravitational waves. It consists of three drag-free satellites flying in a triangular…
UV LED charge control of an electrically isolated proof mass in a Gravitational Reference Sensor configuration at 255 nm
Karthik Balakrishnan, Ke-Xun Sun, Abdul Alfauwaz +15
Precise control over the potential of an electrically isolated proof mass is necessary for the operation of devices such as a Gravitational Reference Sensor (GRS) and satellite mis…
LAGRANGE: LAser GRavitational-wave ANtenna at GEo-lunar Lagrange points
J. W. Conklin, S. Buchman, V. Aguero +36
We describe a new space gravitational wave observatory design called LAGRANGE that maintains all important LISA science at about half the cost and with reduced technical risk. It c…
