abstract = "{This letter presents a dual-quadrature phasemeter, an implementation of
a phase-locked loop designed to track the phase of homodyne and
heterodyne intersatellite laser links. Dual-quadrature
phasemeters use dual-quadrature optical detection to enable an
alternate phase readout scheme that operates with wider
bandwidths and on signals with carrier-frequency differences
down to dc. Analytical modeling demonstrates that dual-
quadrature phasemeters overcome the bandwidth limitations of
conventional phasemeters. Numerical simulations of noise
linearity tests found that the phase-tracking error of the dual-
quadrature phasemeter is less than 10 microcycle/Hz in the
presence of nonlinear cyclic errors. The dual-quadrature
phasemeter enables exploration of an optical configuration for
retroreflector-based space geodesy missions with architecture
similar to that implemented in the Gravity Recovery and Climate
Experiment Follow-On mission. One such alternate configuration
is proposed that is capable of tracking satellite separation
without requiring a frequency offset between local and incoming
light, eliminating the need for optical frequency shifters.}",
