Locations of messages received by Argos satellites also received by Motes in orange versus not received by Motes in light blue for Motes 13X0002 on San Clemente Island and 14X0011 on San Nicolas Island in Southern California (2 top maps) and Motes 14X0003 and 14X0005 on Maui island in Hawaii (2 bottom maps). The yellow pins indicate the location of the Motes on the different islands, and the solid lines indicate the direction of their respective two antennas. Color of pixels indicates percentage of signals received by Argos satellites present within 0.1°-side squares that were also received by Motes with brightest color areas being areas where Motes detect 100% of these signals. Dashed lines show the maximum distance of signal detection. Note that the locations indicated here only show messages received by Argos satellites that were also simultaneously received by Motes. They do not include the additional messages that were only received by Motes as it is impossible to assign a location to them
