1. A method of tracking a moveable object, comprising: sensing at least one characteristic of the moveable object using a sensor of an acquisition system; sensing at least one characteristic of the moveable object using an auxiliary sensor; transmitting a data link update from the auxiliary sensor to the acquisition system; conditioning the data link update to provide a composite likelihood, wherein the conditioning includes: differencing the data link update and at least one predicted characteristic of the moveable object to produce at least one residual; and determining the composite likelihood based on the at least one residual; and adjusting a viewing direction of the sensor based at least in part on the composite likelihood resulting from the conditioning of the data link update.
