1. Determines orbits for objects whose observations are submitted to the Minor Planet Center.
2. Function as part of a team in the processing of orbital elements and related information received by the Minor Planet Center. This includes checking data for both reliability and relevance, consulting with the contributors when appropriate.
3. Function as part of a team to use existing procedures for making more sophisticated identifications of newly reported objects with minor planets observed only very perfunctorily in the past, so that new objects can as a result be considered known and their orbits added to the main database.
4. Function as part of a team to assist with the design and development of substantial modifications to current techniques for the determination of orbits from observations.
5. Function as part of a team to assist with the discovery and correction of errors in the MPC's orbital and observational databases.
6. Function as part of a team to assist with the development of new orbital integration and propagation routines, as well as the introduction of modem mathematical and physics techniques to the differential correction problem.
7. Function as part of a team to assist with the application of new procedures for determining the orbits of minor planets.
8. Assist in the preparation of reports on activities by the Minor Planet Center and on
