1. A method, comprising:
determining, by a processing system including a processor, and for a first anchor in a network of anchors, a relative location of a second anchor in the network with respect to the first anchor based on a range measurement and an angle measurement, wherein the range measurement and the angle measurement are obtained based on a wireless signal transmitted from the first anchor and received by the second anchor, or transmitted from the second anchor and received by the first anchor;
determining, by the processing system, relative locations of one or more additional anchors in the network with respect to the first anchor and the second anchor based on one or more additional range measurements and one or more additional angle measurements, wherein the one or more additional range measurements and the one or more additional angle measurements are obtained based on one or more additional wireless signals transmitted from one or more of the first anchor and the second anchor and received by the one or more additional anchors, or transmitted from the one or more additional anchors and received by one or more of the first anchor and the second anchor;
obtaining, by the processing system, manual measurements of particular coordinates for a set of anchors in the network, wherein the manual measurements of the particular coordinates are made during or after the determining the relative location of the second anchor or the determining the relative locations of the one or more additional anchors; and
causing, by the processing system, the manual measurements of the particular coordinates, information regarding the relative location of the second anchor with respect to the first anchor, and information regarding the relative locations of the one or more additional anchors with respect to the first anchor and the second anchor to be utilized for calculating coordinates of at least some of the anchors in the network.
