Assess vulnerability to safeguard your space assets.

Space Object Threat Assessment (SOTA) helps you determine the risk of a threat object targeting another object. It provides a measure of vulnerability (called the Vanguard Number) that characterizes how likely a specific action is and how soon it could happen. You can conduct this vulnerability analysis quickly and simultaneously for all operational assets to provide mission assurance for any space-based system. This analysis supports all orbit regimes: LEO to LEO, GEO to GEO, LEO to GEO, and everything in between.
