Query: Application of algorithms for high precision metrology   This paper evaluates the performance of algorithms suitable to process the
measurements from two laser beam metrology systems, in particular with
reference to the Gaia Basic Angle Monitoring device. The system and signal
characteristics are reviewed in order to define the key operating features. The
low-level algorithms are defined according to different approaches, starting
with a simple, model free method, and progressing to a strategy based on the
signal template and variance. The signal model is derived from measured data
sets. The performance at micro-arcsec level is verified by simulation in
conditions ranging from noiseless to large perturbations.
