The Astrodynamic Standards were developed to ensure interoperability for users of the Joint Space Operations JSpOC satellite catalog. In order to obtain the most accurate prediction, users need to apply the same propagator models that were used to generate the satellite catalog. The accuracy of an Astrodynamic Standard algorithm is primarily a function of its underlying physics model and the accuracy and compatibility of the data it uses.  It is easy to understand that the "better" the underlying physics model or the more accurate the data, the more accurate the algorithm's calculation.  However, it is not as intuitively obvious that the prediction model must also be compatible with those models generating the orbital data that it uses as input.  The bottom line is, if you are a user of the JSpOC satellite catalog (either TLEs or Vector Covariance Messages (VCMs)), you should use the same propagators that were used to generate the TLEs or VCMs in order to get the most accurate prediction.

DSoft Technology is well-versed in using and integrating Astrodynamic Standards, having worked with the standards and Air Force Space Command since 2003.  Since then we have performed configuration management, testing, integration, and distribution of the Astrodynamic Standards and understand the complexity of their integration and use.  We can assist authorized clients to integrate the standard DLLs into other applications using a C# wrapper.

The following describes each standard in more detail:
