Line-of-sight acceleration of a compact binary coalescence (CBC) event wouldmodulate the shape of the gravitational waves (GWs) it produces with respect tothe corresponding non-accelerated CBC. Such modulations could be indicative ofits astrophysical environment. We investigate the prospects of detecting thisacceleration in future observing runs of the LIGO-Virgo-KAGRA network, as wellas in next-generation (XG) detectors and the proposed DECIGO. We place thefirst observational constraints on this acceleration, for putative binaryneutron star mergers GW170817 and GW190425. We find no evidence ofline-of-sight acceleration in these events at $90\%$ confidence. Prospectiveconstraints for the fifth observing run of the LIGO at A+ sensitivity suggestthat accelerations for typical BNSs could be constrained with a precision of$a/c \sim 10^{-7}~[\mathrm{s}^{-1}]$, assuming a signal-to-noise ratio of $10$.These improve to $a/c \sim 10^{-9}~[\mathrm{s}^{-1}]$ in XG detectors, and $a/c\sim 10^{-16}~[\mathrm{s}^{-1}]$ in DECIGO. We also interpret these constraintsin the context of mergers around supermassive black holes.
