摘要

We examine the constraints that satellite-acquired supernova (SN) apparent magnitude versus redshift data will place on cosmological model parameters in models with and without a constant or time-variable cosmological constant Λ. Data that could be acquired in the near future would result in tight constraints on these parameters. For example, if all other parameters of a spatially flat model with a constant Λ are known, the SN data should constrain the nonrelativistic matter density parameter Ω0 to better than 1% (2%, 0.5%) at 1 σ with neutral (worst case, best case) assumptions about data quality.
