IAWN was established (2013) as a result of the UN-endorsed recommendations for an international response to a potential NEO impact threat, to create an international group of organizations involved in detecting, tracking, and characterizing NEOs. The IAWN is tasked with developing a strategy using well-defined communication plans and protocols to assist Governments in the analysis of asteroid impact consequences and in the planning of mitigation responses.
Currently, IAWN includes members from Europe, Asia, South and North America.

Understanding Orbital Uncertainties in the Context of Impact Predictions
(Aug 2021) II: Orbit Fitting-Least Squares Technique for Orbit Estimation
Second in a series of articles detailing the concept of orbital uncertainties as it relates to impact predictions. Celestial mechanics can be a complicated subject, but here we'll try to distill some of these difficulties and render the subject a bit more transparent.
