We implement inflation within a realistic supersymmetric SO(10) model in which the doublet-triplet splitting is realized through the Dimopoulos-Wilczek mechanism, the MSSM {mu} problem is resolved, and Higgsino mediated dimension five nucleon decay is heavily suppressed. The cosmologically unwanted topological defects are inflated away, and from {delta}T/T, the B-L breaking scale is estimated to be of order 10{sup 16}-10{sup 17} GeV. Including supergravity corrections, the scalar spectral index n{sub s}=0.99{+-}0.01, with vertical bar dn{sub s}/dlnk vertical bar < or approx. 10{sup -3}.
