1. A precision landing system for an unmanned aerial vehicle (UAV), comprising:
one or more anchors configured for placement in proximity to a landing zone;
a tag configured for securement to the UAV, wherein the tag is further configured to wirelessly communicate with at least three or more of the anchors when the UAV is in proximity to the landing zone;
a controller in communication with the tag, wherein the controller is configured to fly the UAV towards a centerline axis which represents a center of the landing zone and defined through a first airspace zone defined at a first altitude above the landing zone, wherein the controller is further configured to maintain the UAV within the first airspace zone until the UAV has descended to the first altitude,
wherein the controller is further configured to fly the UAV towards the centerline axis defined through a second airspace zone defined at a second altitude which is below the first altitude, wherein the controller is further configured to maintain the UAV within the second airspace zone until the UAV has descended to the second altitude, and
wherein the controller is further configured to fly the UAV towards the centerline axis defined through a third airspace zone defined at a third altitude which is below the second altitude, wherein the controller is further configured to maintain the UAV within the third airspace zone until the UAV has descended to the landing zone.
