A least squares method is presented for the solution of orbital and bias parameters for multiple Global Positioning System satellites being observed by a common station array. The effects of radiation pressure modelling errors on timing solutions are examined for both multiple and single satellite processing using a time equation consisting of a bias and linear drift term. Results indicate that the errors in orbital and timing solutions caused by modeling errors in radiation pressure are reduced by the multiple satellite processing scheme. However, adequate time solutions from single satellite processing are achievable if accurate radiation pressure modeling is available.
