It is designed for anyone who wants space-weather, propagation, solar, geomagnetic, satellite, and signal-environment context in a clean situational-awareness display.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs Guardian a forecasting tool?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGuardian provides at-a-glance awareness using public data and heuristic indicators.

Guardian centers on space weather, propagation conditions, solar and geomagnetic activity, satellite visibility, and the signal environment. Sentinel centers on Earth awareness, geophysical context, satellite visibility, grayline, and local weather\/alerts. Both can be useful on their own, and many users run them side by side.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this on multiple computers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYour license covers a single computer and single user.
