TRACE (computer program)

TRACE is a high-precision orbit determination and orbit propagation program. It was developed by The Aerospace Corporation in El Segundo, California. An early version ran on the IBM 7090 computer in 1964.^[1] The Fortran source code can be compiled for any platform with a Fortran compiler.

When Satellite Tool Kit's high-precision orbit propagator and parameter and coordinate frame transformations underwent an Independent Verification and Validation effort in 2000, TRACE v2.4.9 was the standard against which STK was compared.^[2]

As of 2013, TRACE is still used by the U.S. Government and some of its technical contractors.
