The Intercept plug-in allows the user to designate a moving target (TGT) on the map and calculate a route from their current location to the target given multiple parameters such as intercept bearing into target and route type to target. When a target is flagged for intercept, range rings are drawn around the target at its location that are configurable by the user. The plug-in uses the Drifter plug-in, if installed, to automate the TGT’s movement if necessary. Lightweight map widgets provide detailed information such as ETE, ETA to TGT, current speed, distances to target and allows setting a TOT to calculate speed and track whether the user is on time or behind.
