New ways to get GP data now available! Up until now, we've used the TLE format to ingest data into SGP4. With the growth of the catalog soon to exceed the current range of 5-digit catalog numbers, you may be wondering how we will handle that. If so, be sure to check out our prototype Current Data page and read the article titled "A New Way to Obtain GP Data (aka TLEs)." More to follow on Twitter @TSKelso.
