Towards a tilt-to-length coupling calibration on the GRACE follow-on laser ranging instrument
Author(s): H. Wegener

Paper Abstract

The Laser Ranging Instrument (LRI) measures the biased range between the two GRACE Follow-On spacecraft (launched in May 2018) using laser interferometry. It is the first of its type and serves as a technology demonstrator. Here we present the working principle and a brief report on the first turn-on of the instrument. In particular, we will discuss the laser link acquisition and possible methods of calibrating Tilt-to-Length coupling.
