I didn't know about the n-vector representation - cool! It seems that averaging positions in n-vector (i.e. finding the center between the two antennas) is just the normalized mean of the two vectors: http://www.navlab.net/nvector/#example_7 I would use that to calculate the position of a virtual antenna in the middle of the two. --- [Visit Topic](https://discourse.ros.org/t/tractobots-my-attempts-at-field-robots/1486/16) or reply to this email to respond.
