Retroreflector for GRACE follow-on: Vertex vs point of minimal coupling
The GRACE Follow-On mission will monitor fluctuations in Earth’s geoid using, for the first time, a Laser Ranging Interferometer to measure intersatellite distance changes. We have investigated the coupling between spacecraft rotation and the intersatellite range measurement that is incurred due to manufacturing and assembly tolerances of the Triple Mirror Assembly (TMA), a precision retroreflector to ensure alignment between in- and outgoing laser beams. The three TMA mirror planes intersect...[Show more]
