This international standard (NWIP) provides details and associated requirements for tools, techniques, and analyses required to identify launch windows and associated closure times for Safety Launch Collision Avoidance (LCOLA) and (in an informative annex) Mission Assurance LCOLA. The methods evaluate the estimated close approach distances and corresponding collision probabilities between the set of all launch system and deployed objects, and the set of all on-orbit objects.
