  New precise unpolarised differential cross sections of deuteron-proton
elastic scattering have been measured at 16 different deuteron beam momenta
between $p_d = 3120.17\;\textrm{MeV}/c$ and $p_d =3204.16\;\textrm{MeV}/c$ at
the COoler SYnchrotron COSY of the Forschungszentrum J\"ulich. The data, which
were taken using the magnetic spectrometer ANKE, cover the equivalent range in
proton kinetic energies from $T_p = 882.2\;\textrm{MeV}$ to $T_p =
918.3\;\textrm{MeV}$. The experimental results are analysed theoretically using
the Glauber diffraction model with accurate nucleon-nucleon input. The
theoretical cross section at $T_p = 900\;\textrm{MeV}$ agrees very well with
the experimental one at low momentum transfers $|t| <0.2\;(\textrm{GeV}/c)^2$.
