Description

The SGP4 object provides access to the United States Space Force SGP4 propagation algorithm, included in FreeFlyer's installation package through the AstroStds library. The included DLL files are stored in the FreeFlyer installation directory under "Support Files\Engine\Third Party\64_Bit\AstroStdsSgp4Prop". This directory also includes a license file to enable users to access the open source SGP4 implementation. This library also supports the SGP4-XP algorithm, which is used with TLE data in ephemeris type 4 format and includes Solar Radiation Pressure modeling. See the Two-Line Element Set File page for more information.
