We present a unified string supergravity model based on a string-derived SU(5)× U(1) model and a string-inspired supersymmetry breaking scenario triggered by the F-term of the universally present dilaton field. This model can be described by three parameters: mt, tanβ, and m g. We work out the predictions for all sparticle and Higgs masses and discuss the prospects for their detection at the Tevatron, LEPI,II, and HERA. We find that the cosmological neutralino relic density is always within current expectations (\ie, Ωχh20\lsim0.9). We also consider a more constrained version of this supersymmetry breaking scenario where the B-term is specified. In this case tanβ can be determined (tanβ≈1.4-1.6) and implies mt\lsim155\GeV and mh\lsim91\GeV. Thus, continuing Tevatron top-quark searches and LEPI,II Higgs searches could probe this restricted scenario completely.
