State of the Art

The publication of the IAA Cosmic Study on STM 2006 defined Space traffic management (STM) as: “the set of technical and regulatory provisions for promoting safe access into outer space, operations in outer space and return from outer space to Earth free from physical or radio-frequency interference.” This lead to the subsequent creation of the Space Debris Mitigation Guidelines of UNCOPUOS of 2008 and the ISO 24113:2011 Space Systems – Space Debris Mitigation standards. These standards are necessary but not sufficient to reduce the risk of collisions. A viable STM program faces a great barrier caused by the ever-increasing number and variety of orbiting objects ranging in size from a few microns to several meters and the planned future large constellations. In addition, most debris objects cannot be tracked and motion cannot be accurately measured or simulated. The current two line element (TLE) sets and associated processes used for disseminating data about space debris are not adequate for precision conjunction analysis or accurate long term prediction.  In order to ensure that the space environment is resilient to anomalies and catastrophic events and its exploitation is sustainable  a comprehensive STM system must be implemented, integrating improved space situational awareness (SSA), long term orbit prediction, debris removal, re-entry risk assessment and new tools to support space operators.

Objectives

WP8 covers all activities related to the future evolution of the space environment, the required change in operations, the problem of planning and executing collision avoidance manoeuvres and the deployment and dispose of future constellations.
