Abstract:
Operations in geosynchronous orbit are important for many aspects of commerce.
Avoiding conjunctions in an ever increasingly crowded geosynchronous environment is
therefore becoming more important especially in light of the Iridium 33 / Cosmos 2251
collision. SOCRATES-GEO has combined owner operator numerical ephemerides with
Two-Line Element (TLE) set information for over 2 years. Unfortunately, the TLE
information is of limited quality, and obtaining high quality ephemerides is often difficult.
Previously we explored how we could replace the TLE data for those objects for which we do
not get operator data (non-participating SOCRATES-GEO operational satellites or debris).
The International Scientific Observing Network (ISON) resource provides high-quality
optical observations on numerous GEO satellites. This paper introduces additional orbit
determination results of optical data and seeks to understand what observation mix is
necessary to meet certain accuracy requirements.
