In 1909 he became director of the Moscow Agricultural Institute. Iveronov determined the latitudes of Moscow and six district capitals by observing the zenith stars with a transit instrument (1892). He conducted observations of the oscillation of rotating pendulums in Pulkovo, Moscow, and Moscow Province to investigate the Moscow gravitational anomaly; for the same purpose he determined the deflection of the vertical with respect to longitude at several points in Moscow Province.
