  A major part of the future COMPASS program is dedicated to the investigation
of the nucleon structure through Deeply Virtual Compton Scattering (DVCS) and
Deeply Virtual Meson Production (DVMP). COMPASS will measure DVCS and DVMP
reactions with a high intensity muon beam of 160 GeV and a 2.5 m-long liquid
hydrogen target surrounded by a new TOF system. The availability of muon beams
with high energy and opposite charge and polarization will allow to access the
Compton form factor related to the dominant GPD $H$ and to study the
$x_{B}$-dependence of the $t$-slope of the pure DVCS cross section and to study
nucleon tomography. Projections on the achievable accuracies and preliminary
results of pilot measurements will be presented.
