We present numerical simulations to define the observational requirements for determination of the structure and kinematics of the broad-line region (BLR) in active galactic nuclei through reverberation mapping of emission lines. Our results suggest the BLR can be reverberation-mapped to good precision with spectra of signal-to-noise ratio per pixel of about 30, time resolution of about 0.1 day, and duration of about 60 days. Data sets of this quality require dedicated space-based monitoring platforms, such as the Kronos multiwavelength observatory that will be submitted to NASA for consideration as a Medium Explorer (MIDEX). The authors are grateful to NASA for support of these simulations.
