Abstract
A system to acquire and track vehicles travelling in airspace, sea and land via a constellation of satellites. The system includes: (a) means for detecting a first signal from a vehicle; (b) a process for detecting anomaly from the first signal and determining whether it occurs inside or outside a first radar mode coverage area; (c) means for detecting a second signal from the vehicle under a first radar mode if the anomaly occurs inside its coverage area; (d) means for detecting a third signal from the vehicle under a second radar mode if the anomaly occurs outside the first radar mode coverage area; and (e) means for (i) refining the second or third signal from the vehicle under a third radar mode, such that the first, second, third and fourth detecting means are sequentially activated to detect the first, second and third signals by each satellite.
