Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space (SOCRATES)

Space Flight Mechanics Conference
AAS 05-124

Kelso, T.S. and S. Alfano, "Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space (SOCRATES)," presented at the 2005 AAS/AIAA Space Flight Mechanics Conference, Copper Mountain, CO, 2005 January 23–27.

Abstract

As a service to the satellite operator community, the Center for Space Standards & Innovation (CSSI) offers SOCRATES—Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space. CSSI runs a list of all satellite payloads on orbit against a list of all objects on orbit using the catalog of all unclassified NORAD two-line element sets (TLEs) to look for satellite conjunctions for the coming week. The runs are made using, STK/CAT and the NORAD SGP4 propagator implemented in STK. This paper will discuss how SOCRATES works and how it can help satellite operators avoid undesired close approaches through advanced mission planning.

6th US-Russian Space Surveillance Workshop
Session 2.2

Kelso, T.S. and S. Alfano, "Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space (SOCRATES)," presented at the 6th US-Russian Space Surveillance Workshop, St. Petersburg, Russia, 2005 August 22–26.

Abstract

As a service to the satellite operator community, the Center for Space Standards & Innovation (CSSI) offers SOCRATES—Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space. CSSI runs a list of all satellite payloads on orbit against a list of all objects on orbit using the catalog of all unclassified NORAD two-line element sets (TLEs) to look for satellite conjunctions for the coming week. The runs are made using, Satellite Tool Kit’s Conjunction Analysis Tools (STK/CAT) and the NORAD SGP4 propagator implemented in STK. This paper will discuss how SOCRATES works and how it can help satellite operators avoid undesired close approaches through advanced mission planning.
