RE: BASIC SGP4 Algorithm wanted

Title: RE: [amsat-bb] BASIC SGP4 Algorithm wanted


James's Plan13 more closely matches SGP, ... it does not do the same as SGP4. Though I do admit that most people will not see much difference in the results (its only the purists that get wound up about the errors).

A substantial subset of SGP4 (the one usually used in amateur
radio applications) is available in BASIC (with an explanatory
article) at http://www.amsat.org/amsat/articles/g3ruh/111.txt
